A method of secure data transmission in WSN based on certificateless signature technology

In recent years, certificatesless signature was considered to be a critically acclaimed way of key distribution. It was proved to have certain advantages and has been applied to different areas. Based on certificateless signature, this research proposes a security routing pattern in WSN network where a node-role is only used to authorize other nodes. In this pattern, the anchor nodes act as the third party during the transmission and maintenance of network data in the whole system. Not only can they ensure the security of network operation, but also protect the node safety information from other parties. This scheme can guarantee the safety of node during the transmission, and use the features of WSN system to save energy consumption as far as possible.
