Two-factor authentication key agreement protocol suitable for multi-gateway wireless sensor network

Abstract

The invention provides a double-factor authentication key agreement protocol suitable for a multi-gateway wireless sensor network. The protocol is divided into five stages: an initialization stage, aregistration stage, a login stage, an authentication stage and a key change stage. Fuzzy verification and honeywords methods are adopted in the user authentication part, so that the united password identity guessing attack based on the stolen intelligent card is effectively resisted. In the scheme, key negotiation is based on discrete elliptic curve encryption and can resist sensor capture attacks, so that the forward security of the protocol is ensured.

Description

technical field [0001] The invention belongs to the technical field of cryptographic protocols, and relates to a two-factor user identity authentication and session key negotiation protocol applicable to a multi-gateway wireless sensor network environment. Background technique [0002] Wireless sensor networks (Wireless Sensor Networks, WSN) monitor, perceive and collect information of various environments or monitoring objects in real time through various integrated micro-sensors collaboratively, and process the information through a random self-organizing wireless communication network to communicate in multiple ways. The jump relay method transmits the perceived information to the user terminal, so that the user can fully grasp the situation in the monitoring area and make a response. Due to the many types of sensors in wireless sensor networks, and the characteristics of economy and real-time, it has a wide range of applications. It can be used in military, medical, avi...

Problems solved by technology

[0004] At this stage, the authentication and key agreement protocol of wireless sensor network has been continuously proved to have different degrees of security loopholes.

And there are few authentication and key agreement protocols in the wireless sensor network designed based on the multi-gateway communication model.

Once the attacker exploits the loopholes in the authentication protocol to steal the data of the wireless sensor network nodes and intercept the user's private information, it will pose a huge threat to the wireless sensor network and users.
