Efficient and Secure Authentication Scheme Based on Certificateless Aggregate Signature in Space Networks
Abstract— According to the requirements of the space networks for computing cost, communication cost
and security, a new efficient certificateless aggregate signature algorithm is proposed. The signature length is
only 2 group elements, the verification stage requires only 3 pairing operations, and the algorithm is proved
secure based on the computational Diffie-Hellman problem under the random oracle model. Compared with
the other similar algorithm, this algorithm achieves higher security with higher efficiency and lower cost of
communication. Then according to the signature algorithm proposed in this paper, an authentication scheme
with the function of mutual authentication, aggregate authentication and group key agreement is presented.
The analysis results show that the scheme is secure and efficient, especially suitable for the large-scale space
