An Identity-Based Security Mutual Authentication Method Combining the Advantages of Broadcasting

Abstract

The invention discloses an identity-based safety mutual-authentication method combined with broadcast advantage. The technical scheme is to construct an identity-based safety mutual-authentication system composed of multiple to-be-authenticated user nodes UN, an authentication server AS, a safety core node CN, and a private key generation center PKG. An identity-based cryptography parameter initialization module and a private key generation module are arranged on the PKG; an authentication server signature generation module, a user signature verification module and an AS message transceiving module are arranged on the AS; a data broadcast module and a data forward module are arranged on the CN; a user signature generation module, an authentication server signature verification module and aUN message transceiving module are installed on the UN. The PKG in the system generates system parameters, a system main key, and private keys of the AS and the UN, the AS and the UN perform the safety mutual-authentication under the participating of the CN by utilizing the system parameters and the private keys, the problem that the time cost and the storage overhead are large when the internetequipment performs the safety authentication, and the effectiveness of the internet node safety authentication is effectively improved.

Description

technical field [0001] The invention relates to the field of Internet security communication, in particular to an identity-based security mutual authentication method combined with broadcasting advantages. Background technique [0002] With the rapid development of Internet technology, large-scale Internet systems are deployed in many aspects such as urban construction, industrial control, and smart life, which greatly improves work efficiency and reduces labor costs. However, at the same time, the characteristics of the Internet system, such as numerous nodes and wide coverage, make Internet security problems very prominent. At present, there are a large number of terminal nodes in the Internet that are mainly connected to access nodes through wireless networks for information transmission. The openness of wireless networks makes them vulnerable to security threats such as identity forgery, privacy violations, and denial of service attacks. Security authentication is the c...
