Lightweight certificateless signature and key agreement scheme for WSNs
Hao Wang · Journal of Jilin University · 2014
In this paper,a lightweight certificateless signature scheme is proposed for Wireless Sensor Networks(WSNs)under the condition of limited recourses.The signature scheme is more efficient by using online/offline approach and has no bilinear pairing operation during signing and verifying process compared with the Xirrus Management System(XMS)and Paterson scheme.Based on this signature scheme,a key agreement scheme is also proposed,which can be used by every two nodes in WSN to establish a session key safely.Finally,this signature scheme is proved to be securing that can defense the two attacks proposed in Al-Riyami and Paterson security model,and the security proof can be reduce to discrete logarithm problem.
