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

Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the present invention.

[0018] like figure 1 Shown is a flow chart of a preferred embodiment of the communication channel dynamic encryption method of the present invention. The method is used in the communication field to realize the establishment of a reliable communication connection between the server and the client. The method specifically includes the following steps.

[0019] Step S01, establishing key stores on the server and the client respectively. Specifically, the server include...

Abstract

The invention relates to a communication channel dynamic encryption method. The method includes: respectively building key libraries at a service end and a client; by the client, randomly selecting a first encryption scheme to build a communication with the service end; by the service end, encrypting and verifying the authentication message transmitted by the client during communication building; by the service end, verifying and comparing the key library version number of the client to decide whether to update the key library of the client or not; by the service end, randomly distributing a second encryption scheme to encrypt the authentication, for logging in the service end, of the client; by the service end, randomly distributing a third encryption scheme to encrypt communication data. The communication channel dynamic encryption method has the advantages that each data interaction of the method is encrypted; before the service end distributes the third encryption scheme, only the encryption schemes are needed to be transmitted on channels instead of specific keys; after the service end distributes the third encryption scheme, the encryption schemes are bond to the conversion of both sides, and only the encrypted communication data needs to be transmitted.

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...
