Certificateless Public Key Cryptography (CL-PKC) overcomes not only the key escrow problem in public key cryptography but also the cost of the certificate publishing and management in the Certificateless Public Key Cryptography (CL-PKC). No certificate public key cryptosystem just meet the requirements of this, but it relies on a special authentication server, which has high operating costs and lack of flexibility and it cannot meet the requirements of wireless sensor networks directly. Considering these problems, a multi-node of synergy certificateless authentication approach is proposed for WSN. The certificate of the nodes would be done by the certification set. And the set was consited of trusted neighbor nodes. Analysis indicates that this certification meets the security requirements of general wireless sensor networks and has advantages of low-cost and high efficiency.
