In order to share the resource and information in a military aircraft, all avionics systems are interconnected using avionics data bus. COMmunications SECurity (COMSEC) is an important issue in an aircraft network. Any intrusion or information leakage will lead to a risk to the military tasks. The key security problem is how to construct a secure link between two AAPs (Avionics Application Processes)...
Certificateless cryptography, first introduced by Al-Riyami and Paterson in 2003, can solve the key escrow problem which is inherent in identity-based (ID-based) cryptography and eliminate the use of certificates as in the conventional Public Key Infrastructure (PKI). Recently, Xu et al. proposed a certificateless signature scheme and Yang et al. presented a mediated certificateless signature scheme...
A new formal model of security for proxy signature schemes is presented and a provably secure short proxy signature scheme is proposed from bilinear maps. The proposed proxy signature scheme is based on two short secure signature schemes. Finally, a security proof of the proposed proxy signature scheme is showed by reducing directly the security of the proxy scheme to the security of the two basic...
