Robust Key Management scheme for certification in mobile ad-hoc networks

This paper proposes robust key management scheme (RKM ): a new certification management scheme for mobile ad-hoc networks. RKM, based on threshold cryptography, ensures better robustness compared to other schemes proposed in the literature. In particular, it guarantees the confidentiality of the private key of the certification authority, even if the number of compromised nodes exceeds the threshold of vulnerability. Thus, our model offers better protection against many attacks such as mobile adversary attack.
