Research on Secure Transmission Scheme in Wireless Sensor Network

Abstract

Abstract-In order to achieve secure communication in WSN, a lightweight encrypting transmission scheme based on symmetric cryptographic algorithm is proposed. In the scheme, a combined secret key generation algorithm is used to generate one-time secret key, hardware encrypt device is used to distribute symmetric secret keys and establish secure transmission protocol. The experiment results show that the scheme is with high execute speed and low energy consumption, and clearly superior to popular protocols.
