Authentication scheme for roaming in aeronautical Ad hoc networks
航空自组网漫游接入认证方案

Authentication is a crucial security requirement when one aircraft communicating with other aircrafts belong to another domain. For the existing scheme can not satisfied with user anonymity and high efficiency at the same time, this paper proposed a identity-based authentication scheme for roaming in aeronautical Ad hoc networks. It constructed the aircraft authenticate with aircrafts in other domain with the private key by partial private key and the secret value. The verification result of the signature was a constant with respect to the signer's identifier, which realized secure authentication and user anonymity. And this scheme avoided the pairing operation. It is shows that the proposed scheme has superiority in both security and efficiency.
