Paper Abstract

Nowadays, there are some works with free-space laser communication system, but security issues of this network are always neglected. We present an efficient online/offline routing based on identity-based signature for ad hoc networks with Free-Space-Optics (FSO). The protocol is especially suitable for ad hoc networks with FSO because the major computational overhead is shifted to the offline phase, whereas the online phase requires only a very low computational overhead to achieve a full scale of authentication. In addition, since the signature scheme uses an identity-based cryptosystem, it does not need to maintain a public key directory and to exchange any certificate. The effectiveness of our protocol is simulated using QualNet tools.
