Anti-traceability-attack wireless sensor network lightweight access authentication method and system

Abstract

The invention belongs to the technical field of communication network security, and discloses an anti-traceability-attack wireless sensor network lightweight access authentication method and system, and the method comprises the steps: a user interacts with a gateway node to complete registration; the sensor device interacts with the gateway node to complete registration; after the user and the sensor equipment are registered, authentication and key negotiation are carried out with the help of the gateway node; and after the user node completes authentication by using the old password, the user node autonomously selects an updated password. The method can be better applied to resource-limited Internet of Things access equipment, has relatively low calculation overhead, resists common attacks, has good user anonymity and non-traceability, ensures that mutual authentication of a user and sensor equipment and session key negotiation can be effectively realized in an access authentication process, and improves the user experience. The method can have lower calculation overhead, and is more suitable for being applied to the scene of Internet-of-Things resource limited equipment.

Description

technical field [0001] The invention belongs to the technical field of communication network security, and in particular relates to a lightweight access authentication method and system for a wireless sensor network resistant to retroactive attacks. Background technique [0002] At present, the concept of the Internet of Things (IoT) first appeared in 1999, which refers to the real-time collection of information required for applications through information collection devices and technologies, and the interconnection of things and things, things and people through network connections. . The Internet of Things is based on the traditional Internet, but it is different from the Internet in that its access devices have expanded from PCs, mobile phones and other devices that need to interact with people to all ordinary physical objects that can be independently addressed, thereby realizing the Internet of Everything. With the proposal of Industry 4.0 and the rapid development of...

Problems solved by technology

Specifically: in the above scenario, if an attacker monitors, intercepts, and tampers with the communication information of the open link, thereby stealing the identity information or other authentication information of the entity to be authenticated, this will pose a threat to the security of the entity to be authenticated. and divulge the content of the communication

Second, if a lightweight authentication scheme cannot be implemented, resource-constrained wireless sensor devices cannot perform complex calculations, resulting in the inability to implement the authentication scheme
