Wireless network security transmission method, system and equipment

Abstract

The invention discloses a wireless network sending terminal secure transmission method, comprising the following steps: generating a receiving terminal public key according to the receiving terminal identifier; using the receiving terminal public key to encrypt a session key, using the session key to be transmitted The data in the information is encrypted and sent to the receiving terminal, so that the receiving terminal decodes to obtain the data. The invention discloses a wireless network receiving terminal safe transmission method, an authentication center, a receiver device and a sender device. In the embodiment of the present invention, a set of key system is established, so that the mobile terminals participating in this session can obtain the public key information of the other party without information interaction, but directly according to the identification information of each mobile terminal participating in this communication. Get its public key information.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a wireless network security transmission method, system and equipment. Background technique [0002] In 2005, the International Telecommunication Union (International Telecommunication Union) released the ITU-T (International Telecommunication Union Telecommunication Standardization Group) X.805 specification, which proposed access control, authentication, and non-repudiation (receivers determine whether to receive) for end-to-end network systems. The destination terminal of the message is this terminal, not other terminals), data confidentiality, communication security, data integrity, availability, and privacy. At present, it is difficult for wireless communication networks to fully meet the special security requirements of mobile data services. In particular, due to the particularity of some data services, sensitive information (such as keys, user sensitive info...

AI Technical Summary

Problems solved by technology

[0007] To sum up, in the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: in the prior art, improvement methods are proposed based on the security mechanism of the wireless network itself, although the end-to-end The encryption mechanism or authentication mechanism is more flexible, but its principle still depends on the security services provided by the network service provider, and does not fundamentally solve its security problems
