Abstract

The invention discloses a wireless sensor network authentication method and a system, and electronic equipment, and aims to solve the problems that off-line password guessing attacks cannot be resisted and forward security cannot be ensured. The method comprises the following steps: carrying out initialization setting on a gateway node and a sensor node of the wireless sensor network by utilizingan elliptic curve modular multiplication, and determining basic identity information; accessing the wireless sensor network by the sensor node and a user terminal according to the basic identity information; determining a target sensor node according to the communication request of the user terminal; and adopting corresponding authentication negotiation modes for different target sensor nodes, andauthenticating and negotiating the user terminal and the target sensor nodes to determine a session key. The system and the electronic equipment are used for executing the wireless sensor network authentication method.

Description

technical field [0001] The invention relates to the technical field of communication security, in particular to a wireless sensor network authentication method, system and electronic equipment. Background technique [0002] Wireless sensor networks (wireless sensor networks) are the key components of the Internet of Things to sense the surrounding environment and collect data, and are widely used in smart homes, public safety, and medical health. The data sensed by sensor nodes are transmitted through public networks, and sensor nodes are often deployed in unattended or even hostile environments, which makes WSNs vulnerable to attacks. Therefore, providing a secure identity authentication and key agreement protocol to verify the user's identity and encrypt communication content is very important to ensure network security. Existing password-based multi-factor remote user authentication protocols generally have the problems of being unable to resist offline password guessing...
