To solve the privacy-preserving problem during the roaming authentication of wireless mobile networks, a novel roaming authentication scheme with anonymity was presented.An efficient certificateless aggregate signature scheme was first constructed, by introducing the online/offline signature and combining the aggregate signature.Com-pared with the related schemes, the proposed scheme has higher efficiency in computations Riding Gaiters of both signature and verifi-cation, and also improves the efficiency in communications.
Furthermore, based on the proposed signature scheme, a novel roaming authentication scheme with anonymity was presented, in which it simplified Hockey Accessories - Home Sharpening - Machines the traditional three-party au-thentication model.The theoretical analysis shows that this scheme is secure and effective, and thus it is especially suit-able for large-scale wireless mobile networks.
