Embodiment
For the feature of the batch session of the client such as instant messaging, note and multi-conference on the equipment such as mobile terminal, the present invention proposes to carry out bulk encryption chat and many people encrypt the method for chat, chat content can represent with the form of ciphertext, only has correct key and could automatically decipher and batch deciphering display plaintext.
Hereinafter will be described in detail to embodiments of the invention by reference to the accompanying drawings.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.
Below in conjunction with accompanying drawing, embodiments of the invention one are described.
During bulk encryption session, the both sides of communication are before the session carrying out batch or in conversation procedure, open automatic decryption mode in advance and configure the automatic decruption key of oneself client, like this in batch conversation procedure, after the both sides communicated receive and dispatch enciphered message, system by the ciphertext in automatic decrypted session record and show in conversation recording deciphering after plaintext (just in interface display, be automatically shown as the plaintext after deciphering, still store with ciphertext in the conversation recording of backstage), conversation recording still can ciphertext after conversation end or when next time consults, key must be re-entered could again decipher.Reach like this and both achieved bulk encryption session, be convenient to again the plaintext conversation recording checking ciphertext in communicating pair communication process intuitively.
Many people encryption session is the popularization of above-mentioned bulk encryption session method, and the object of session can be many people group session more than two people and two people.During many people encryption session, different people can configure the key of varying number---and the universal key that everyone has can be configured, also groups of people the private key only having this part talent to have can be configured.Universal key is used for all encryption sessions; Private key is used in group session process, and just can be encrypted deciphering between the groups of people only grasping this key and exchange, other group session member only can see ciphertext.In conversation procedure, all participation people of session or the people of partial session open automatic decryption mode in advance and configure the automatic decruption key of oneself client, like this in conversation procedure, after having encrypted cipher text session to occur, the people with association key can decrypting ciphertext automatically, does not have key or the incorrect side of key can only see other people ciphertext conversation recording.
The key link of bulk encryption session is:
(1) both sides communicated appoint the key of session in advance, before session or in conversation procedure, configure the encryption key of information encryption in systems in which.
(2) side communicated inputs expressly in the information input frame of communication software, when being necessary encryption, there is the control of encryption function or other interface is encrypted the information in input frame by clicking, be encrypted as the plaintext in the ciphertext replacement input frame of specific format, send ciphertext afterwards, ciphertext sends to the other side by the existing communication function of software.
Input expressly has encryption function hover button with click and sees Fig. 1 ~ Fig. 2 to the schematic diagram be expressly encrypted.
(3) the transmitting-receiving record interface of communicating pair is ejected and is automatically deciphered hover button after monitoring the ciphertext of specific format, the one side or both sides of communication ejects the key dialog box of deciphering automatically after clicking self-suspending button, opens the automatic decryption mode of oneself client after input key.
After ciphertext being detected in conversation recording, Fig. 3 is shown in by the schematic diagram of display automatic deciphering hover button, and Fig. 4 is shown in by the schematic diagram that click automatic deciphering button inputs key.
After automatic decryption mode is opened, be expressly (just in interface display, be automatically shown as the plaintext after deciphering, still store with ciphertext in the conversation recording of backstage) automatically by the decrypt ciphertext in current sessions record.When continuing batch session, often during a newly-increased conversation recording, if conversation recording is also specific ciphertext form, and when the key of current automatic decryption mode mates with ciphertext, then automatic is expressly display by newly-increased decrypt ciphertext, otherwise does not deal with newly-increased session content.Whether automatic decryption mode is only effective to communication one side opening this pattern, open do not affect the opposing party, if the opposing party does not open automatic decryption mode, chat record is still ciphertext display.
After opening automatic decryption mode, Fig. 5 is shown in by the schematic diagram of automatic decrypting ciphertext, and after continuing bulk encryption session, Fig. 6 is shown in by the schematic diagram of the ciphertext that deciphering is new automatically.
In conversation procedure, when opening automatic decryption mode, again clicking and automatically deciphering button, will close automatic decipher function, now recovery is shown as ciphertext by all decrypted plaintexts.
(4) work as conversation end, again open former conversation recording, or return to again interface, foreground after session interface is placed in backstage, automatic decryption mode gives tacit consent to closedown all automatically.Again open automatic decryption mode to need to re-enter decruption key.
Fig. 7 is shown in by automatic decryption mode shows ciphertext schematic diagram after being closed by step (4) situation.
Fig. 8 is shown in by the entire flow schematic diagram of bulk encryption session of the present invention.
Many people encryption session is the popularization of above-mentioned bulk encryption session, is applicable to the group session situation of more than two people and two people.The key link of many people encryption session is:
(1) each side's part communicated or all members appoint the key of session in advance, before session or in conversation procedure, configure the encryption key of information encryption in systems in which.Owing to being many people group session, different people can configure the key of varying number.Such as, the universal key that everyone has can be configured, also groups of people can configure the private key only having this part talent to have.In the layoutprocedure of key, need, to the corresponding self-defined title code name of each cipher key configuration, to select when being convenient to subsequent decryption.
(2) in multi-conference process, one side of communication inputs expressly in the information input frame of communication software, when being necessary encryption, select to there is the control of encryption function or other interface is encrypted the information in input frame by clicking, be encrypted as the plaintext in the ciphertext replacement input frame of specific format, send ciphertext afterwards, ciphertext sends to the other side by the existing communication function of software.In click ciphering process, if transmit leg configured in advance multiple encryption key (as being configured with universal key and private key simultaneously), then the applicable scope needing transmit leg to send content according to this selects corresponding universal key or private key.For the fail safe of key, key selects the title code name only arranged with step (1) of the public or private key in interface to show, certainly, selects interface also can add or revise new key at this key.
(3) the transmitting-receiving record interface of communication parties is ejected and is automatically deciphered hover button after monitoring the ciphertext of specific format, the each side of communication ejects the key automatically deciphered and adds interface after clicking self-suspending button, opens the automatic decryption mode of oneself client after input key.If user has multiple key, then can add interface at key and add multiple automatic decruption key.
(4) after decryption mode is opened automatically, by each decruption key that traversal step (3) configures, attempt with each key come automatically by the decrypt ciphertext in current sessions record for expressly (being just automatically shown as the plaintext after deciphering in interface display, still with ciphertext storage in the conversation recording of backstage).If there is key energy successful decryption ciphertext in ergodic process, then no longer travel through other key; If all keys all can not successful decryption, then session content is kept not deal with.When continuing batch session, often during a newly-increased conversation recording, then automatically automatically travel through key according to mode above and carry out decryption processing, reach the effect of deciphering automatically.Whether automatic decryption mode is only effective to communication one side opening this pattern, open do not affect other communication parties, if other communication parties do not open automatic decryption mode, chat record is still ciphertext display.
(5) in conversation procedure, when opening automatic decryption mode, again clicking and automatically deciphering button, will close automatic decipher function, now recovery is shown as ciphertext by all decrypted plaintexts.
(6) work as conversation end, secondaryly open former conversation recording, or return to again interface, foreground after session interface is placed in backstage, automatic decryption mode gives tacit consent to closedown all automatically.Again open automatic decryption mode to need to re-enter decruption key.
Fig. 9 is shown in by the entire flow schematic diagram of the present invention many people encryption session.
For above-mentioned bulk encryption session and many people encryption session, can modify in interactive mode, encryption and decryption mode, cipher key configuration etc., include but not limited to other alternate embodiments:
In above-mentioned decryption method, automatic decryption mode open be detect there is ciphertext in conversation recording after self-suspending show, and after clicking automatic deciphering button, input that clear crytpographic key opens again again.Password configuration during the opening and encrypt of automatic deciphering is separately and independently, and for the purpose of simplification, these two modules can combine: 1) configure encryption and decryption key in cipher key configuration module simultaneously, and automatic decruption key directly calls encryption key to decipher;
2) automatically decryption mode can when configuring cipher key with regard to manual unlocking, and just self-suspending and just opening after needing input decruption key after not needing to detect ciphertext; 3) decryption mode can global configuration be opened automatically, as long as namely have input after correct security permission controls and open automatic decryption mode with regard to the overall situation, only have the automatic decryption mode of manual-lock just to close this function, thus save the operation of frequently opening automatic decryption mode.
In above-mentioned decryption method based on the identical symmetrical encryption and decryption mode of encryption and decryption key, the asymmetric encryption and decryption mode of public key encryption, private key deciphering can be replaced with.Such as, in many people many people encryption session methods, the PKI of the groups of people in sender-selected group session is encrypted, and communication parties only has the private key ability decrypting ciphertext of the groups of people of selected PKI after receiving ciphertext.
Such as:
1, in above-mentioned decryption method, implementation can only realize for communication software itself or realize the present invention by cell phone platform framework.For unrealized mobile phone terminal of the present invention, also can receive the ciphertext realizing terminal of the present invention and send, but the function of deciphering automatically can not be possessed.This can substitute by providing independent decrypt ciphertext client application.
2, in above-mentioned decryption method, automatically decipher except all ciphertexts except opening automatic decryption mode, user also can decipher the encryption session of each band ciphertext one by one when not opening and maybe can not opening automatic decryption mode.
3, in encryption process, the input mode of the key of encryption and decryption is except the text such as digital, alphabetical, other key modes can also be included but not limited to: a) pattern key mode, namely in Encrypt and Decrypt process, key is the pattern of agreement in advance, be encrypted by the corresponding relation of pattern and specific key, and when deciphering, first input pattern, deciphered by the corresponding relation of pattern and specific key.B) gesture key mode, namely in Encrypt and Decrypt process, key is the gesture of agreement in advance, is encrypted, and first inputs gesture when deciphering, deciphered by the corresponding relation of gesture and specific key by the corresponding relation of gesture and specific key; B) mode such as other bio-identification such as face, palmmprint, vocal print, fingerprint, encryption process be all first set up associated biomolecule feature and specific key corresponding relation to carry out encryption and decryption process.
Below in conjunction with accompanying drawing, embodiments of the invention two are described.
Embodiments provide a kind of decryption method, use the method, in the session of the communications applications of mobile terminal, can be encrypted display and deciphering display to information, improve fail safe, idiographic flow as shown in Figure 10, comprising:
Step 1001, determine whether to open the automatic decryption mode of current sessions;
In the embodiment of the present invention, the information that described information comprises issued information and receives from Correspondent Node.
In this step, mobile terminal can be set and point out when ciphertext being detected user to open automatic decryption mode, also can receive user at any time and indicate unlatching, specific as follows:
1, mobile terminal points out user to open automatic decryption mode when ciphertext being detected;
First, after entering session interface, detect the information comprising ciphertext in the conversation recording of current sessions; When the information comprising ciphertext being detected, whether display opens the information of automatic decryption mode; When the unlatching decryption mode instruction that user inputs being detected, open automatic decryption mode.
2, receive user at any time and indicate unlatching;
Namely, when the unlatching decryption mode instruction that user inputs being detected, automatic decryption mode is opened.
It should be noted that, the automatic decryption mode of choice for use is one of them of multiple implementation to unlatching or closedown decipher function, and other implementations that can realize unlatching or closing function are on mobile terminals all among scope.
The ciphertext comprised in step 1002, information to the conversation recording of described current sessions is decrypted, and obtains the corresponding plaintext of described ciphertext;
This step specifically has two kinds of implementations, and one is that real-time prompting user inputs decruption key, uses this decruption key to be decrypted; Two is use preset one or more decryption key decryption.Specific as follows:
1, real-time prompting user inputs decruption key, uses this decruption key to be decrypted;
First, the decruption key of user's input is detected; Then use described decruption key to be decrypted the ciphertext in described information, obtain the corresponding plaintext of described ciphertext.
2, preset one or more decryption key decryption are used;
First, preset multiple decruption keys are traveled through one by one to the information comprising ciphertext in described current sessions record, then the ciphertext matching corresponding decruption key after traversal is decrypted, obtains the plaintext that this ciphertext is corresponding.To the ciphertext without corresponding decruption key after traversal, be not decrypted operation.
Accordingly, need, at mobile terminal local maintenance decruption key configuration information, in this decruption key configuration information, to comprise multiple decruption key.In described decruption key configuration information, add new decruption key, or delete the decruption key comprised in described decruption key configuration information, or revise the decruption key comprised in described decruption key configuration information, to upgrade this decryption key information.
Step 1003, described ciphertext is replaced to show with described plaintext;
In this step, after deciphering completes, namely can ciphertext be expressly replaced to show; For in an information, comprise ciphertext and expressly two kinds of contents of encryption, ciphertext is replaced with corresponding expressly display, original plaintext is constant.
Meanwhile, in system background, still store described ciphertext.
Under described automatic decryption mode opening, follow-up continuation receives new information or sends new information.To newly receive or the information including ciphertext that newly sends out be decrypted, obtain the plaintext that in described information, ciphertext is corresponding, replace the display of described ciphertext with described plaintext.
After automatic decryption mode is opened, this automatic decryption mode can be closed, mainly through the following two kinds mode:
1, after the session is completed, the automatic decryption mode of described session is closed;
That is, after user exits current sessions, namely close the automatic decryption mode of this session, when user enters same session again, still need the operation of again opening automatic decryption mode.
2, the indication information of closing automatic decryption mode detected, according to this indication information, close automatic decryption mode;
Under this kind of mode, user can close automatic decryption mode at any time as required.
When being in session and decryption mode becomes closedown from unlatching automatically, to decrypted and be shown as the ciphertext of corresponding plaintext, recover display ciphertext.
In addition, under described automatic decryption mode closed condition, when detecting that user specifies the instruction be decrypted one or more information comprising ciphertext, the ciphertext in this one or more information is decrypted, obtains the corresponding plaintext of described ciphertext.Add the flexibility of system.
