Embodiment Construction

[0014] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. The subsequent description of the specification is a preferred implementation mode for implementing the application, but the description is for the purpose of illustrating the general principle of the application, and is not intended...

Abstract

The invention discloses a device and method for encryption protection of link communication and a safety message processing system. The device comprises a request sending module, a first processing module and a second processing module, wherein the request sending module is used by a device A for requesting to negotiate with a device B about a link encryption key; the first processing module is used for calculating and acquiring a link session key and then encrypting, signing and returning to the device A after the device B receives the request; the second processing module is used for calculating in the same manner and acquiring the link session key after the device A receives and verifies the signature; and then, the device A and the device B can negotiate about the encrypted session key for communication in such a manner. The device has the advantages of high safety level, quick negotiation process and suitability for various devices in low processing capacity and high-end devices in high processing capacity. The link communication is encrypted and the encrypted key is temporarily negotiated when the link is established at each time, so that all the data in the communication process can be protected and the adaptability is strong.

Description

technical field [0001] The invention relates to a device and method for link communication encryption protection, and a security message processing system. Background technique [0002] At present, many small handheld devices communicate in clear text, which poses a great security problem. With the rapid development of computer communication technology, more and more important information will be transmitted through the network. Therefore, how to ensure communication data in The security of transmission in the network has become one of the network security issues that people focus on, and the information security technology using encryption as a means has become the core research point of network security. Existing encryption methods include: DES encryption algorithm: DES algorithm is a block encryption algorithm. This algorithm divides the data to be encrypted into groups of 64 bits, and the key used is also 64 bits, but because every 8 bits are used as a parity bit, there...
