The Elliptic Curve Digital Signature Algorithm (ECDSA) is the elliptic curve analogue of the Digital Signature Algorithm (DSA). It is used in wireless sensor networks in order to establish security and allow legitimate users to join in the network and disseminate messages into the networks. The ECDSA needs an addition point and two multi scalar for verifying users' signature in WSNs, that because decrease signature verification speed, in result it has also incurred a series of problems such as high energy consumption and long verification delay. In this paper the authors propose an efficient technique to accelerate signature verification in WSNs by exploiting cooperation among sensor nodes.
