Geo-decentralized federated learning (FL) can empower fully distributed model training for future large-scale 6G networks.Without the centralized parameter server, the peer-to-peer model synchronization in geo-decentralized FL would incur excessive communication overhead.Some existing studies optimized synchronization interval for communication eff

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
