<![CDATA[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 ID-based aggregate signature scheme with constant pairing computations. Compared with the existing ID-based 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. DOI : http://dx.doi.org/10.11591/telkomnika.v12i1.3456]]>
