Step S02, the application server are produced according to the RSA public key acquisitions request for receiving in the way of one-time pad
The different RSA key pair of life, and RSA public keys therein are handed down to the RSA public key acquisitions module；
It is described after step S03, the RSA public key acquisitions module receive the RSA public keys that the application server is issued
AES key generation module is randomly generated AES key in the way of one-time pad；
The RSA public keys that step S04, the digital envelope generation module are obtained using the RSA public key acquisitions module, to institute
The random AES key for stating the generation of AES key generation module is encrypted, and then generates digital envelope；
The random AES key that step S05, the accidental enciphering module are generated according to the AES key generation module is to report
Literary data are encrypted, and generation needs the ciphertext of transmission；
Step S06, the data summarization generation module generate data summarization according to ciphertext content, and the data summarization has inspection
Test the function whether being tampered in ciphertext transmitting procedure；
Step S07, the data transmission blocks send jointly to the digital envelope of generation, ciphertext and data summarization
The HTML5 modules, and then give the application server by the HTML5 module transfers；
Step S08, the application server decrypt digital envelope according to the private key of RSA key pair, obtain the client
The random key that AES key generation module described in end is produced, original message number is decrypted into using random AES key by ciphertext
According to while ciphertext is generated into data summarization, the data summarization sent with the HTML5 modules is compared, if two data
Summary is identical, illustrates that ciphertext is not tampered with during transmission, to realize the integrity protection of communication data, otherwise
Ciphertext is tampered, and this data communication is invalid.
The beneficial effects of the invention are as follows：Using multiple encryption algorithms, the encryption side of one-time pad is used in ciphering process
Formula, and using public key carry out it is secondary encryption form digital envelope, further enhancing the security of ciphertext, the contrast of data summarization
Process can verify whether ciphertext is tampered in transmitting procedure, and financial letter is enhanced in all directions from generation and transmitting procedure
Cease the security of transmission.
