The present invention is achieved with step by the following method:
Each element that the present invention realizes is given first and gives relevant definition, and definition includes following element: cipher key source, cipher key source are big
Small, added value, plain code cipher key source pointer, cipher key source addressing pointer carry out above-mentioned element for title, in which: key source size generation
In referred to as M, added value generation, claim m, and plain code cipher key source pointer generation claims N, and cipher key source addressing pointer generation claims n；
The cipher key source is a biggish non-ordered data set, includes all ascii characters in addition to null character in set.
The key source size (generation claims M) and added value (generation claims m), set sizes M is according to use demand and system energy
It depending on tolerances, reduces M and is at least minimal to 2Kb, take 16Mb or more bigger better in the unconfined situation of password digit.M is
When cipher key source not being recycled, key addressing pointer still has available key selection when reaching cipher key source bottom, that is, one is answered
Primary communication maximum number of byte chooses identical key in order to which both sides are synchronous, needs to send a plain code password source and wipes needle.
The plain code cipher key source pointer (generation claims N), N is when communicating every time to tell recipient in a position of cipher key source
It sets, cipher key source addressing pointer n is stored in this position.Communication initiator generates a random number, obtains by divisor remainder of M
N.Plain code pointer and cipher key source addressing pointer n length are three bytes.
The cipher key source addressing pointer (generation claims n), finds this position in cipher key source with plain code cipher key source pointer N, later
The values of three bytes obtain n by divisor remainder of M.Start bit of the key that this is communicated in this, as generation in cipher key source
It sets.
The present invention improves cipher key source and reduces M to 2Kb, hexadecimal 0800Hb, facilitates to program with increase extra-code
Method avoid be recycled cipher key source, take added value m size be 256b, hexadecimal 0100H, plain code cipher key source pointer N and
Cipher key source addressing pointer n shorten to 2 bytes.Concrete operations are that bank increases M=2Kb, a m=256b to user account data,
Total hexadecimal is the cipher key source attribute column of 0900Hb byte space, content be in all users it is unique, unordered, by
The character set of any ASCII composition, and by duplicate copy to user.
Utilize above-mentioned carry out data encryption, decrypting process:
Data encryption process is sent, uses time number of seconds to generate a random number as seed first, generates a plain code cipher key source
Pointer N, then cipher key source addressing pointer n is generated from cipher key source with this pointer, existed with the key that this pointer finds this encryption
Initial position in cipher key source, the text size encrypted as needed intercept this secondary key from cipher key source, will communication text with it is close
Key from first to last carries out exclusive or by every byte and produces communication ciphertext, and plain code cipher key source pointer N is then added the communication just generated
Ciphertext is sent to communication object as the text of this secondary transmission.
Data decrypting process is isolated plain code cipher key source pointer N, is generated in cipher key source with N after receiving communication ciphertext
Cipher key source addressing pointer n finds initial position of the key of this encryption in cipher key source with this pointer, decrypts as needed
Text size intercepts this secondary key from cipher key source, and communication text is from first to last carried out exclusive or by every byte with key and is produced
Urtext, it can be seen that this process is as ciphering process, the difference is that " ciphertext " that finally generates is exactly originally secondary connect
" original text " received.
It is three bytes as the preferred cipher key source addressing pointer N length.
Two bytes are foreshortened to from three bytes as the preferred plain code pointer N, cipher key source addressing pointer n also contracts from three bytes
It is as short as two bytes.
It needs to encrypt now with a character string as preferably described, this cipher key source M=2Kb, m=256b.
Described in preferably, the set sizes in secret key source are depending on use demand and system energy tolerances preferably 18
Position password, which is limited, produces 12K, and no limit for cryptographic digit takes at least 16Mb or more.
A method of safe and secret transaction is carried out using cipher key source encryption method is improved:
Prerequisite condition and rule before trading:
1. mobile phone user opens bank net trading account, account information includes at least account, address name, identification card number, hand
Machine number, cipher key source.Bank " card " is no longer sent out to user by bank, and also there is no fixed passwords.Verifying user identity just uses aforementioned
The random cipher proof method that cipher key source encryption is provided with decryption method, mobile phone user obtain special account cipher key source and are previously stored
Convenient on " companion " of client's carrying and keeping；
2. mobile phone user and gathering hotel owner register in third party's connecting platform in advance, at least wrapped in registration user information attribute column
Include address name, identification card number, cell-phone number, GPS, IP address, the bank of deposit, the information such as personal head portrait photo, as beneficiary
GPS and IP address are indispensable, and Cash collecting equipment should be equipped with the bluetooth devices of energy broadcast GPS, activity IP address or in intranet
Cash collecting equipment must when opening gathering process by the IP address currently obtained upload to third party's connecting platform filling IP belong to
In property column.
3. bank, which changes tradition, provides the login mode of account number cipher, logged in using identification card number plus name instead of account,
Account no longer discloses, and use when being served only for user's remittance abroad money and querying the balance imports someone identification card number when importing money
Add the agreement of name account.It binds identification card number and cell-phone number only in inside to bank account, does not embody binding externally.It allows
Identification card number and cell-phone number become bright number of safety.
Step 1 mobile phone obtains the GPS information of Cash collecting equipment by receiving the bluetooth devices of hotel owner, this GPS information is sent
To connecting platform, connecting platform helps mobile phone to be attached with Cash collecting equipment according to the network address that GPS value finds hotel owner, thus mobile phone
Information interchange can be carried out with Cash collecting equipment, and obtains hotel owner's identification card number, name from platform, and these silver-colored information of opening an account.
Cash collecting equipment obtains the head portrait of mobile phone user from connecting platform, shows as the start button bitmap for transmitting information with mobile phone user
On Cash collecting equipment, if there are several customers at this time, just there are several head portraits to show on Cash collecting equipment, each head portrait represents
The process being connect with a mobile phone, Cash collecting equipment at this time mobile phone with maintain the connection, but there is no information interchange, mobile phone exists
Wait standby bill of collecting money；
Step 2 mobile phone shopping user chooses commodity, after hotel owner's shopping bill is formed, passes through and observes trading object, selected element
It hits corresponding mobile phone user's head portrait and bill is sent to payment mobile phone, it is desirable that Mobile Phone Payments；
After step 3 mobile phone receives bill, payment information is sent to company of handset, itself bank of deposit of company of handset storage
Network address connect bank server, the identification card number+name of itself is sent to server by mobile phone plain code, while by hotel owner
Identification card number add name, bank is sent to after beneficiary bank of deposit and bill encryption, bill payment is pressed by request bank；
Step 4 bank server finds user key source according to identity card+name of mobile phone user, and generates a random character
String, encrypts this character string with cipher key source and is sent to mobile phone, the verifying password as this time mobile phone user's identity.
After step 5 mobile phone is connected to the verifying character string ciphertext of server, be sent to company of handset, company of handset to ciphertext into
Row decryption generates former character string, then original text it is motionless re-encrypted is carried out to this character string with cipher key source self, while encrypting account
Number, by the verifying character string encrypted and account ciphertext, the machine of fighting hand to hand is sent to bank server together.
Step 6 bank server checks whether re-encrypted, and judgment method is that plain code pointer is different, then decrypts confirmation and be
No is the character string just sent out, and confirmation is that the account after re-inspection decryption is errorless, and confirmation is verified just now, bank's clothes
The payment information that business device is sent by step 3 mobile phone user is remitted money to bank, payee by bill, sends money to mobile phone after completion
Information is converged；
Step 7 mobile phone obtains after taking the information that device payment is completed, and successful payment is informed to the Cash collecting equipment of hotel owner；
The bank account of step 8 Cash collecting equipment inquiry self, prompts hotel owner to pay goods after confirming account, and hotel owner's hand over of goods is handed over
It is readily accomplished.
Before veritifying each success communication as the preferably step 6 transaction or mobile phone and bank account and terminating password source according to
Cipher key source encrypting and decrypting rule, adjust automatically key source structure form new cipher key source and use for communication next time, concrete operations
Communicating pair is changed respective cipher key source as follows:, will be several since this chooses the starting point byte of key
Byte is divided to two sections of tail portions and head for moving on to cipher key source, and the foundation of mobile byte number is the word of the low three-bit value of starting point byte
Joint number moves on to the tail portion of cipher key source, then the head of cipher key source is moved to by low three byte numbers of that back to back byte.Through
This movement adjustment, produce three new tie points, i.e. the more several bytes in head, produces a new tie point with protocephalic region,
Secondly middle part chooses the previous byte of key starting point from this and produces one with the rear portion beginning for removing several bytes
New tie point, third are that protocercal tail portion and several bytes of new in-migration produce a new tie point.It furthermore is exactly cipher key source
The position of all bytes produces variation relative to original cipher key source, to become a new cipher key source.
Before terminating as preferably described step 6 transaction or mobile phone and each success communication of bank account veritification, bank service
Device and company of handset synchronous adjustment key source structure form new cipher key source and use for communication next time.The specific method is as follows: from this
It is that starting point byte starts that key is chosen in secondary transaction, is divided into upper byte and lower byte by its front and back is arranged in, then chosen
The secret key of upper and lower part at least one byte of initial point byte secret key, be classified as tail portion that two sections move on to cipher key source respectively and
Head；
Wherein: the secret key byte movement rule that upper byte will move is the low three-bit value of starting point byte, (if it is more
A byte) it keeps existing and puts in order (can again random), it is aligned to after cipher key source the last byte；
The secret key byte movement rule that lower byte will move is that the neutral gear of existing position byte is downward after upper byte is mobile
Low three positions byte, (if it is multiple bytes) keep it is existing puts in order, these three bytes are successively shifted into arrangement
At the top of to this cipher key source before first character section.
Through this movement adjustment, three new tie points are produced, i.e. several more bytes of head, with former first character section
Produce a new tie point；After several bytes are removed in centre, next part is brought up, and forms a new tie point；Protocercal tail
Several bytes of portion and new in-migration form a new tie point.Moving relative position locating for each byte of original cipher key source
Changed after dynamic, it is a completely new cipher key source.
It is company of handset as preferred " companion "；The present invention is equipped with a company of handset to user, and company of handset is
One intelligent monolithic system, inside have microprocessor, running memory and flash memory and bluetooth communication, be made into key chain,
The implements not easy to lose such as bracelet, wrist-watch.Company of handset is carried out wireless communication using bluetooth and hand family mobile phone, and setting bluetooth is minimum
Power keeps communication distance most short, and mobile phone is with companion using particular encryption at uniquely coupled.The function of company of handset is one is storage
The bank address cipher key source and account of user, at the same can also store user other it is related link network address, cipher key source and account, and
The various certificate data such as various identity documents followed by carry out data when running banking or other occasions verifying identity
Encrypt and Decrypt, then started by mobile phone and bank or other equipment data exchange.Monitor the operation of cell phone application, entire agiotage
Process is by the data judging mobile phone operation process decrypted according to companion.
Also be accompanied with a bluetooth devices as the preferred Cash collecting equipment, the bluetooth devices when payee networks,
The device is written into the GPS measured value of Cash collecting equipment, if having its user's identical value, can adjust and then be written in right amount the device
Part, and it is registered in the attribute column of the connecting platform Cash collecting equipment.Cash collecting equipment is broadcasted in Cash collecting equipment work for payment mobile phone
GPS value.Broadcast adjustable be subject to of effective range does not interfere with each other with adjacent equipment.Introduce the benefit of this bluetooth equipment
Have at 3 points, one is wartime contingency GPS will not be interrupted by transaction is closed, that is, no longer according to lazy GPS；The second is solving floor and going out
Existing GPS overlap problem.The third is solving that the GPS accuracy that measures of mobile phone is not high and receiving unit density is big, there are also dead angles GPS etc. to ask
Topic.
When as the preferred progress step 5, Cash collecting equipment obtains the head portrait of mobile phone user from connecting platform, which is
Mobile phone user is when third-party platform is registered, user's head portrait photo that scene is taken pictures, and transmits opening for information as with mobile phone user
Dynamic button bitmap is shown on Cash collecting equipment, if there is several customers at this time, just has several head portraits to show on Cash collecting equipment.
Be 0.5-3 meter as the bluetooth devices of the preferred company of handset or Cash collecting equipment communication effective distance, mobile phone and
Companion is using particular encryption at uniquely coupled.
The characteristics of present invention comparison similar technique, is: one, improve " a kind of infinite length key internet communication encryption method ", it is special
It is not to one 16Mb or more of communicating pair and to carry out corresponding lower reconciliation structure above the application attribute of identical cipher key source
Adjustment.
The present invention adjusts cipher key source by dynamic, i.e., adjusts key source structure before each success communication terminates, form
New cipher key source is that communication next time uses, to shorten in cipher key source length, still is able to realize " unlimited " long cipher key source.Specifically
Operation communicating pair is changed respective cipher key source as follows:, will since this chooses the starting point byte of key
Several bytes are divided to two sections of tail portions and head for moving on to cipher key source, and the foundation of mobile byte number is the low three-bit value of starting point byte
Byte number move on to the tail portion of cipher key source, then the head of cipher key source is moved to by low three byte numbers of that back to back byte
Portion.It through this movement adjustment, produces three new tie points, i.e. the more several bytes in head, produces one with protocephalic region and newly connect
Contact, secondly middle part is chosen the previous byte of key starting point from this and is produced with the rear portion beginning for removing several bytes
One new tie point, third are that protocercal tail portion and several bytes of new in-migration produce a new tie point.It furthermore is exactly close
The position of all bytes in key source produces variation relative to original cipher key source, to become a new cipher key source.
The present invention provides account encryption method, first according to the low three-bit value ring shift left of corresponding secret key byte before encrypting, then
Exclusive or encryption is carried out again, decryption method is: extensive further according to the low three-bit value ring shift right of corresponding secret key byte after progress exclusive or decryption
It is again original account.This method has been known by people by solution major part account, does not handle directly encryption and exposes key instead, needs
It is re-encrypted after account data is handled.
The present invention utilizes improved cipher key source encryption and decryption, innovates a kind of random cipher Authentication Method, random cipher body
Part proof method is exactly the password that both sides do not arrange in advance, and when verify identity, authentication one random string of generation is with close
The side of being verified is issued after choosing key encryption in key source, and the side of being verified chooses key with cipher key source self after receiving and decrypts, then uses
The cipher key source of the side of being verified self again encrypts random cipher, then returns authentication, after authentication receives, first judges whether
Re-encrypted, then judge whether be whether being proved to be successful from issued character string to determine, the identifying code of this method its
Essence is lifetime extremely short disposal password, sends an encrypted characters string from authentication to the side of being verified -- it is i.e. disposable close
Code, to the side's of being verified decryption, re-encrypt and send authentication back to, life cycle be exactly two network transfer times and one decryption and
One re-encrypts the time of process.And this target -- remittance bill is proved to be successful in authentication and completes mesh at once at this time
Mark -- remittance, centre do not have any gap bored.No matter process of exchange uses that interception pin mode in the prior art all
Can not obtain final password within so short time, due to the particularity of this encryption method, each encrypted text with it is close
The respective function relationship of text is all different, and is not to be obtained a result with a kind of algorithmic language to carry out operation, only corresponding according to lazy key
Position in the ASCII of byte.It is possible that certain can be just extrapolated in the case where key is only recycled, and this method is never heavy
Again use key, and using company of handset remember hundred million cipher key sources, for identifying code mistake be zero tolerance refusal guess password, as long as therefore
Companion, which does not lose password, to break.Even if sending out random code with plain code, it is desirable that encryption is sent back to, is also without identical synchronisation key source
It can not obtain the ciphertext of verifying password for allowing server to approve.If intercepting the ciphertext of user encryption at this time, and shield worn-out user,
Ciphertext is sent by eavesdropper camouflage user orientation server, server can only be completed by that bill remittance transferred in advance by encryption
Money, to complete this transaction, password is also from this failure, it is impossible to generate " interests " to appropriator, that is to say, that hijacker without
Method is inserted into their bill, useless having kidnapped the disposable verifying password of user.To realize break off that malice is forced to be robbed
The case where holding.
The present invention can also be generated a random string, will be used in user login services device with the authentication server true and false
Family identification card number address name plain code and this random string of encryption issue server, and server presses user's body card number plus surname
Name finds the cipher key source of the user, then this encryption random string decryption is returned after re-encrypted to user.User sentences
Whether disconnected be re-encrypted, and verify whether be it is primary go out random string, determine true and false server, this method is exactly
User gives server one disposal password, and the effect of bi-directional verification may be implemented.
Two, continue to improve " method that mobile phone is connect automatically with internet computer "；The present invention is to solve GPS location precision
Insufficient problem provides a bluetooth devices to beneficiary, and the bluetooth devices are when Cash collecting equipment networks, by Cash collecting equipment
GPS measured value, if having its user's identical value, can adjust and then be written in right amount the device, and be registered in connecting platform should
The attribute column of Cash collecting equipment.The GPS value of Cash collecting equipment is broadcasted for payment mobile phone in Cash collecting equipment work.Broadcasting effective range can
It is subject to and adjusts not interfered with each other with adjacent equipment.Before mobile phone comes Cash collecting equipment, bluetooth GPS broadcast is then arrived in mobile phone inspection, no
Itself measurement GPS again, is directly accurately positioned by connecting platform with the GPS of broadcast and connects Cash collecting equipment.It solves simultaneously by GPS
Closing affects, and uses Beidou signal in the future.
