THE METHOD FOR GENERATING THE DYNAMIC CRYPTOGRAM IN NETWORK TRANSMISSION AND THE METHOD FOR TRANSMITTING NETWORK DATA

摘要

The invention involves the encryption method of the network transmission, discloses a method for generating dynamic cryptogram in network transmission while establishing the connection, improves the security of the thereby enhances the security of the data transmission. The method for generating dynamic cryptogram in network transmission while establishing the connection includes: (A) The client and the server in the network generate first secret key according to the dynamic user information known by the two parties and the first algorithm; (B) The client encrypts the user logging on information and sends it to server using the first secret key and the second encrypt algorithm; (C) The server encrypts the second secret key and sends it to the client using the first secret key and the third encrypt algorithm; (D) The client and the server encrypt data and transfer it each other using the second secret key and the forth encrypt algorithm. According to the above method, the invention also provides the method for transmitting the network data.
