Problems solved by technology

Since neither the server nor the client can judge whether the data packet is sent from the real and legal party, ordinary encryption technology cannot fundamentally solve the data communication security problem of network products, which greatly affects the health of the network environment develop

Abstract

A method for realizing dynamic encryption of a communication channel between a server and a client, the method comprising: establishing a key storehouse at the server and the client respectively; The communication connection; the server decrypts and verifies the authentication information sent by the client when establishing communication; the server verifies and compares the client’s key store version number to determine whether to update the client’s key store; the server randomly assigns the second encryption The scheme encrypts the authentication information for the client to log in to the server; and the server randomly assigns a third encryption scheme to encrypt the communication data. Each data interaction of the communication channel dynamic encryption method of the present invention is encrypted. Before the server distributes the third encryption scheme, it only needs to transmit the encryption scheme instead of the specific key on the channel; communication data.

Description

technical field [0001] The invention relates to communication channel-based encryption technology, in particular to a communication channel dynamic encryption method. Background technique [0002] The current network products are mainly based on the client / server model, the server is managed by the operator, and the client is installed on the user's computer. The communication between the client and the server is completely dependent on the communication of data packets. Many network products encrypt the data packets communicated between the client and the server. Although this can prevent data packets from being stolen, but because the encryption algorithm in the client is fixed and hard-coded, as long as the cracker analyzes the fixed encryption algorithm in the client, he can pretend to be the client or the server to send data packets to The other party cheats; the node between the client and the server can also intercept the communication data packet, decrypt and resto...
