Due to wireless nature of sensor network, secure data transmission is a major issue for wireless sensor network. Clustering is a technique which increases network lifetime and reduces power consumption of sensor nodes in WSN. In this paper, the authors study an authenticate way to data transmission for cluster based WSN. They propose two protocols for authentication of data; those are secure and efficient data transmission protocols SET-IBS and SET-IBOOS, by using Identity-Based digital Signature (IBS) scheme and Identity-Based Online and Offline Digital Signature (IBOOS) scheme.
