Security authentication method based on chameleon hash function

Abstract

The invention discloses a safety certification method based on a chameleon hash function, which relates to the field of wireless communication safety certification of heterogeneous wireless networks and mainly comprises the following operation steps of: firstly, system initialization is performed on a key generation center to select the system public parameters and finish system establishment; the home domain network server HS completes registration; the foreign region network server FS completes registration; the mobile terminal MT completes registration; the home domain network server HS distributes switching authorization information to a legal and credible mobile terminal MT; and the mobile terminal MT and the foreign region network server FS complete authentication switching and session key negotiation. According to the method, the security real-time authentication of the mobile terminal and the foreign region network in the heterogeneous wireless network can be effectively realized, and the identity privacy of the mobile terminal and the resistance to temporary private key leakage and replay attacks are ensured. Moreover, in the authentication process, the mobile terminal consumes less resources.

Description

technical field [0001] The invention belongs to the field of wireless communication security authentication of heterogeneous wireless networks, and in particular relates to a security authentication method based on a chameleon hash function. Background technique [0002] Driven by business and user needs, the fifth-generation mobile communication technology, with its higher transmission rate and lower transmission delay, supports users' high-level demand for information and provides users with a better network experience. The multi-level and coexistence of multiple access modes of the 5G network give it significant advantages in terms of network deployment flexibility and system capacity. The horizontal handover of homogeneous wireless technology is difficult to meet the handover requirements of mobile terminals in 5G networks, and further consideration needs to be given to switching the network connection of mobile terminals from one wireless technology to another, so that ...
