Security enhancement in ad hoc network with ID-based cryptosystem
Jumin Song, Hecyoul Kim, Soo Jin Lee, Hyunsoo Yoon · 2005
As ad hoc network has advanced, the importance of security increases more and more. But it suffers from the restriction that ad hoc network does not have the established infrastructure. In this paper we propose a security-enhanced model with ID-based cryptosystem, which removes the necessity for any infrastructure and provides sound authentication and a more secure and concrete routing protocol with aggregate signature. ID-based aggregate signature scheme, which is also proposed in this paper, removes the necessity for certificate transmission and verification. And it reduces communication cost significantly because our aggregate scheme compresses many signatures into only one signature keeping the same security level as existing signature schemes
