Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] refer to figure 1 Shown is a schematic flowchart of an end-to-end security assurance method for interconnecting communication between a wireless sensor network and the Internet, including:

[0025] S101, deploying several wireless sensor subnets and setting parameters;

[0026] S102, the user provides an identity ID and verifies the validity of the identity;

[0027] S103, the user with a valid identity sends an access request and verifies the access right;

[0028] S104, the user with the access authority negotiates the key with the sensor node, and confirms the key with the node;

[0029] S105, message transmission is performed when the confirmation is valid. specific reference figure 2 Take user U accessing node i through a remote terminal device as an example.

Abstract

The invention provides an end-to-end safety control method for wireless sensor network and internet intercommunication. Part of the certification and access control work is transferred to the gateway of the wireless sensor network, an asymmetric key negotiation mode based on elliptic-curve signcryption technology is adopted to place unsigncryption operation with large computing amount in an Internent remote terminal, and the symmetric key decryption operation is placed in the sensor nodes. Compared with the improved ECC (Elliptic Curve Cryptography)-based SSL (Security Socket Layer) protocol and the improved TLS (Transport Layer Security) protocol based on elliptic-curve identity, the energy consumption of the sensor nodes is effectively reduced, access control and privacy protection are enhanced and Dos (Disk Operating System) attack can be resisted.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to an end-to-end security guarantee method for interconnecting communication between a wireless sensor network and the Internet. Background technique [0002] With the rapid development of wireless sensor network technology, it is urgent to use IP technology (especially IPv6 technology) to interconnect the sensor network with the Internet, and use remote terminals (including PCs, mobile phones, PDAs, etc.) to remotely access sensor nodes through the Internet. , control and management, and extend the connection and communication between people in the Internet to the connection and communication between people and things, and between things and things, so as to realize the ultimate goal of the Internet of Things. In this open environment, when it comes to the transmission and application of some sensitive information, establishing an end-to-end secure connection for the comm...
