Wireless Sensor Network Encryption Algorithm

Wireless sensor networks of research trace the end of 20 century, but security quistion of research appear near a few years. Wireless sensor networks security project is being theory research. The data of wireless sensor networks transmitted in form of wireless, Information be likely to by lawless wiretapping\tamper and destroy at any moment in transmitted process, So It is very important of ensureing data security. Data encrpytion tachniques is a sort of important means of ensuring data security. Although many mature encrpyt algorithm already exist at present, but most encrpyt algrithm cannot apply in wireless sensor networks due to it is characteristic. So that, how to select and implement encrpyt algorithm become the key of safety communication in wireless sensor networks.The text research that encrypt algorithm apply in wireless sensor networks. Base on summarize wireless sensor networks, and contrapose its characteristic, Advance encrypt algorithm must follow principle in wireless sensor networks node data encrypt, Design encrypt algorithm simulae project, Select RC5/6 algorithm as node of encrypt algorithm and TOSSIM as simulae tool of encrypt algorithm, Achieve encrypt algorithm simulation experimentation and realize data encrypt/decrypt in wireless sensor networks. Finally, The text analyse simulation result,validate encrypt algorithm following principle is logical. indcate RC5/6 algorithm is appropriate algorithm, apply on data encrypt of wireless sensor networks.It can achieve requirement of safety communication.
