End-to-end safety control method for wireless sensor network and internet intercommunication

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...

AI Technical Summary

Problems solved by technology

Although these two improvement schemes both reduce the energy consumption of the sensor nodes, the load on the sensor node end is still equivalent to the load on the Internet remote terminal, while the capability of the sensor node end is much weaker than that on the Internet remote terminal.

In addition, the improved scheme cannot provide privacy protection for Internet remote terminals, nor does it implement access control and resist DoS attacks
