Efficient Signature Schemes Based on MABS (Multicast Authnetcation Based On Batch Signature)

In traditional multicast is an internet work service that provides efficient delivery of data from a source to multiple receivers. It reduces the bandwidth requirements of the network and the computational overhead of the host devices. Digital signature provides authenticity, integrity and non-repudiation to many kinds of applications in everywhere computing environment. Existing digital signature schemes are computationally expensive; the ideal approach of signing and verifying each packet independently raises a serious challenge to resource constrained devices. In order to reduce computation overhead, conventional schemes use efficient signature algorithms and are vulnerable to packet injection by malicious.
