Existing digital signature algorithm is computationally expensive the ideal approach of signing and verifying each packet independently raises serious challenge to resource constraint devices. In order to reduce computation overhead the authors are using batch verifier and these algorithm are resilient to packet loss means if one of packet is lost still it will authenticate batch. In this paper, they also identifying bad signature. If batch contain bad signature then the batch is discarded for this they are define divide and conquer verifier.
