Step S1302: it combines the character of the taking-up according to the sequence of taking-up, as the encryption key.
By choosing character in the random string, carry out sequence combination has achieved the purpose that obtain encryption key.
In one embodiment, the random string is " aFk980dhb254YVjP1 ", makes a reservation for take out 5 characters, starting
Character is " 9 ", and the predetermined number being separated by determined is 2, i.e., takes out a character every two characters.5 then successively taken out
Character is " 9 ", " d ", " 2 ", " Y ", " P ", and the character string thus formed is " 9d2YP ".Then by character string " 9d2YP " as encryption
Key.
In one embodiment, in the random string, since at the bebinning character, every predetermined number word
Symbol takes a character, until taking out predetermined number of characters, comprising: if got when predetermined number character takes character
Character and the number of characters at last character interval of the random string be less than or equal to the predetermined number, will be described
All characters of random string successively add behind the last character, to obtained new random string weight
Newly since at the bebinning character, character is taken every predetermined number character, until taking out predetermined number of characters.Example
Such as, the random string is " aFk980dhb254YVjP1 ", makes a reservation for take out 7 characters, bebinning character is " 9 ", and what is determined is pre-
Surely the number being separated by is 3, i.e., takes out a character every three characters.The character successively taken out is " 9 ", " h ", " 4 ", " P ", is taken
When to character " P ", the number of characters with last character interval is 0.All characters of the random string are successively added
It is added in behind the last character, obtains new random string " aFk980dhb254YVjP1aFk980dhb254Y
VjP1".Since bebinning character, in this example, to take out a character every three characters since first character " 9 ".
The character successively taken out is " 9 ", " h ", " 4 ", " P ", " k ", " d ", " 5 ", and the character string thus formed is " 9h4Pkd5 ".Then will
Character string " 9h4Pkd5 " is used as encryption key.
In step S140, according to scheduled Encryption Algorithm, data packet to be sent is added using the encryption key
It is close.

It stores up and is sent to client.It is established in communication protocol used in connection in the two, has arranged specific characteristic information, specified abstract
The algorithm of algorithm, the concrete mode for determining key, encryption and decryption.After server receives the encrypted packet from client, to finger
Determine characteristic information and carry out abstract operation, obtained abstract operation result is consistent with the abstract operation result that client obtains.Service
The result for operation of making a summary is converted to 10 binary digits by device, using the number to pre- less than or equal to random character string length
Measured length carries out modular arithmetic, the starting for the character at the modular arithmetic result will be corresponded on random string being determined as decruption key
Character.
In step S240, since the bebinning character, decruption key is obtained in the random string.
In one embodiment, use DES as enciphering and deciphering algorithm in the communication protocol of server and client agreement, therefore
Encryption key is identical as decruption key.The random string is " aFk980dhb254YVjP1 ", makes a reservation for take out 5 characters, rise
Beginning character is " 9 ", and the predetermined number being separated by determined is 2, i.e., takes out a character every two characters.5 then successively taken out
A character is " 9 ", " d ", " 2 ", " Y ", " P ", and the character string thus formed is " 9d2YP ".Then by character string " 9d2YP " as solution
Key.
In another embodiment, use DES as enciphering and deciphering algorithm in the communication protocol of server and client agreement, because
This encryption key is identical as decruption key.The random string is " aFk980dhb254YVjP1 ", makes a reservation for take out 7 characters,
Bebinning character is " 9 ", and the predetermined number being separated by determined is 3.Thus the character successively taken out is " 9 ", " h ", " 4 ", " P ", is taken
When to character " P ", the number of characters with last character interval is 0.All characters of the random string are successively added
It is added to behind last character, obtains new random string " aFk980dhb254YVjP1aFk980dhb254YVj
P1".Since bebinning character, in this example, to take out a character every three characters since first character " 9 ".According to
The character of secondary taking-up is " 9 ", " h ", " 4 ", " P ", " k ", " d ", " 5 ", and the character string thus formed is " 9h4Pkd5 ".Then by word
Symbol string " 9h4Pkd5 " is used as decruption key.
In step S250, according to scheduled decipherment algorithm, encrypted packet is decrypted using the decipherment algorithm, it should
