A Note on a Secure Routing Method for ad-hoc Networks

ad-hoc 네트워크에서의 안전한 라우팅 기법에 관한 연구

Kim et al. recently proposed an identity-based aggregate signature scheme to construct a secure routing protocol in ad-hoc networks. In this note, we unfortunately show that the identity-based aggregate signature scheme is universally forgeable, that is, anyone can forge the signature of any messages of its choice. This subsequently means that their secure routing protocol is not secure.
