Wireless Sensor Network ( WSN) nodes are severely limited by their power,communication bandwidth,and storage space,and the traditional signature algorithm is not suitable for WSN envi- ronments. In this paper,we present a ring signa- ture scheme designed for WSNs. In this scheme, all of the wireless sensor nodes are divided into several sub-groups and the sub-group nodes are used to generate the signature instead of the WSN cluster nodes. This scheme can effectively avoid the single node failure problem,and it also has a high availability. All nodes are free to sign their own message,and the nodes that generate signa- tures can simultaneously calculate their own part of the signature, meeting the distributed parallel computing requirements. Compared with the tradi- tional ring signature,this scheme reduces the en- ergy consumption,and therefore is very suitable for WSNs.
