Description

technical field

[0001] The invention relates to a two-party authentication key negotiation method and system based on an implicit public key certificate, which can be applied to secure communication in a large-scale distributed network environment (such as the Internet), and belongs to the technical field of network communication. Background technique

[0002] With the increasing popularity of network information technology applications, network information security has increasingly become a subject of much concern. On the one hand, network information technology has made worldwide information exchange more convenient and faster, and at the same time brought more opportunities for business and scientific research to people. On the other hand, once the important information transmitted on the network (such as state secrets, commercial secrets or personal privacy, etc.) is intercepted or tampered with, the country, enterprise or individual will suffer huge losses. In addition...
