Abstract

Aiming at the problems of long time delay and high computation cost of using complex bilinear mapping in the current LEO satellite network authentication scheme, this paper proposed an efficient certificateless authentication scheme based on the Gayathri's certificateless authentication scheme. This scheme unified the user's public key and real identity, so that needn't the third party to participate in the authentication process and reduced the authentication delay. It used a small number of point multiplication and point addition operations on the elliptic curve to construct the authentication message, which didn't involve the bilinear mapping and reduced the computation cost. Then this paper proved the authentication scheme's security based on the assumption of elliptic curve discrete mathematics under the random oracle model. Finally, through experimental simulation, comparing with the existing LEO satellite identity authentication schemes, the proposed scheme has lower authentication delay, computational overhead and communication overhead.
