Example Embodiment
[0104] Example 1
[0105] In this embodiment, the identity-based two-party key agreement protocol is implemented in the form of a website, and the security of the protocol is demonstrated on the website. The details are as follows:
[0106] (1) A new identity-based two-party key agreement protocol.
[0107] The algorithm mainly involved in this protocol is an identity-based key agreement scheme. The identity-based key agreement scheme is composed of three phases: system establishment, key extraction (user’s public and private keys), and key agreement. This system is based on Shim (Shim K. Efficient ID-based authenticated key agreement protocol). Based on Weilpairing.Electronics Letters,2003,39(8):653-654.), the improvement of the identity-based key agreement scheme, the schematic diagram of the identity-based key agreement system is as follows figure 1 , The specific steps of the whole process are as follows:
[0108] (1) System establishment: public system parameters: {G 1 ,G T ,p,...
