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.

Embodiment Construction

[0063] The present invention will be further described below in conjunction with the accompanying drawings.

[0064] FIG. 1 is a communication model diagram of a multi-gateway wireless sensor network in the present invention. The multi-gateway communication model includes three types of entities, sensor nodes, gateway nodes and users. Gateway nodes are divided into home gateway nodes and external gateway nodes. For users and sensor nodes, the gateway nodes that are relatively close to them are called home gateway nodes, and the rest of the gateway nodes are called external gateway nodes. After the sensors and gateway nodes are placed, they are stationary. In wsn, the cost of sending and receiving messages increases with distance. Sensor nodes have the characteristics of low memory, low battery power, low bandwidth, and limited computing power. The gateway node has strong computing power. So we should reduce the computational load of sensor nodes. Sensor nodes are used fo...

Abstract

The invention proposes a two-factor authentication key negotiation protocol suitable for multi-gateway wireless sensor networks. The present invention is divided into five stages: initialization stage, registration stage, login stage, authentication stage and key change stage. In the part of user authentication, fuzzy verification and honeywords are used to effectively resist the combined password identity guessing attack based on stolen smart cards. In this scheme, key agreement is based on discrete elliptic curve encryption, which can resist sensor capture attacks and ensure the forward security of the protocol.

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 suitable for a multi-gateway wireless sensor network environment. Background technique [0002] Wireless Sensor Networks (WSN) cooperatively monitors, perceives and collects information of various environments or monitoring objects in real time through various integrated micro-sensors, and processes the information through random self-organizing wireless communication networks. The skip relay mode transmits the sensed information to the user terminal, so that the user can fully grasp the situation of the monitoring area and make a response. Due to the many types of wireless sensor network sensors, and their economical and real-time characteristics, they have a wide range of applications. It can be used in military, medical, aviation, home, environment and other fields. The security issu...
