Abstract

As the key technology of Pervasive computing, wireless sensor networks node is very limited in its energy, processing power, storage capacity and communications capability, so it’s usually to be considered unsuitable for the use of public key encryption technology. In our article, we propose mutual authentication and session key exchange protocols based on certificates for the wireless sensor networks, and an improved versions for the conventional certificate-based systems are proposed. Our protocol is more efficient than the others in that it requires fewer messages and only one session key. It gives use a new method to deal with such security problems. In designing the security protocol proposed here, the low computational power of the wireless sensors nodes and the low bandwidth of the wireless networks are considered.
