Lightweight anonymous authentication method suitable for resource-limited equipment

Abstract

The invention provides a lightweight anonymous authentication method suitable for resource limited equipment, the method is realized by adopting an information system model, and the information systemmodel comprises three entities of a network management center, the limited equipment and an information center, and specifically comprises the following steps: setting system parameters, registering,signing, verifying and confirming a secret key. The invention can be suitable for equipment with limited computing resources. The invention discloses an anonymous authentication method. Only one elliptic curve point multiplication operation needs to be executed at the authentication end, and compared with a previous elliptic curve-based anonymous authentication method, the method has the advantages that the overhead of computing resources and communication resources is further reduced while the security is ensured, so that the method is more suitable for resource-limited equipment, and the requirement of the equipment on the computing capacity is reduced.

Description

technical field [0001] The invention belongs to the field of information security, and in particular relates to a lightweight anonymous authentication method suitable for resource-limited devices. Background technique [0002] Identity authentication is an important barrier to protect computer systems and data security, but the rapid development of information technology has exposed some disadvantages of traditional identity authentication methods, and users are prone to reveal too much identity information or attribute information during authentication. Therefore, simultaneously protecting user authentication and privacy has become a key issue in the field of information security. The anonymous authentication technology can keep the user anonymous while the user is authenticated, thereby ensuring the privacy of the authenticated user. Therefore, this technology can realize both anonymous authentication and privacy protection. However, the traditional anonymous authenticati...
