Embodiment Construction

[0062] The present invention will be further described below in conjunction with the accompanying drawings.

[0063] 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 remaining gateway nodes are called external gateway nodes. After the sensor and gateway nodes are placed, they are static. In WSNs, the cost of sending and receiving messages increases with distance. Sensor nodes are characterized by low memory, low battery power, low bandwidth, and limited computing power. Gateway nodes have strong computing power. So we should reduce the computation of sensor nodes. Sensor nodes are used for data monitoring and ...

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...
