Abstract

The invention discloses a lightweight digital signature method facing a wireless sensing network based on an elliptic curve cryptography mechanism. The method comprises the following steps: initializing a parameter, establishing a public and private key pair, generating a digital signature, and verifying the signature. By utilizing a deformation of a signature equation in a digital signature verification step for the elliptic curve cryptography mechanism, time-consuming modular inversion operation in original signature generation and verification is changed into additive operation, and a TinyECC 2.0 function library after multiple optimization is introduced at the same time, so operation for ECCs is simple and is easy to understand, the lightweight digital signature method has high safety performance, and generation and verification processes of the digital signature has the advantages of the small computation amount and the fast speed.

Description

technical field [0001] The invention relates to wireless sensor network information security technology, in particular to a light-weight digital signature method for wireless sensor networks. Background technique [0002] Wireless Sensor Network WSN (Wireless Sensor Network), because of its large-scale, self-organization, dynamics, integration and other characteristics, has been widely used in e-commerce, military, transportation, medical and other fields. With the expansion of the application range of wireless sensor network, the value of transmitted information is also increasing, and its security has been widely concerned. However, due to the characteristics of wireless sensor network channel exposure and broadcast transmission, the information needs an effective protection mechanism in the actual transmission process. One of the effective methods is to add a digital signature to the transmitted data, so that the user can verify the authenticity of the information. Effec...
