Id-Based Aggregate Signature Scheme and Its Application in Authenticated Routing

An aggregate signature scheme can aggregate n signatures on n distinct messages from n distinct signers into a single signature. , . Thus n verification equations can be reduced to one So the aggregate signature adapts to Mobile Ad hoc Network (MANET). In this paper, we propose an efficient IDbased aggregate signature scheme with constant pairing computations. Compared with the existing IDbased aggregate signature schemes, this scheme greatly improves the efficiency of signature communication and verification. In addition, in this work, we apply our ID-based aggregate signature to authenticated routing protocol to present a secure routing scheme. Our scheme not only provides sound authentication and a secure routing protocol in ad hoc networks, but also meets the nature of MANET.
