Authentication and Key Agreement Based on Anonymous Identity for Peer-to-Peer Cloud

Cross-cloud data migration is one of the prevailing challenges faced by mobile users, which an essential process when users change their phones to a different provider. However, due insufficient local storage and computational capabilities smart phones, it often very difficult for backup all from original cloud servers in order further upload downloaded new To solve this problem, we propose efficient model between providers construct mutual authentication key agreement scheme based on elliptic curve certificate-free cryptography peer-to-peer cloud. The proposed helps develop trust lays foundation realization cross-cloud migration. Mathematical verification security correctness our evaluated against notable existing schemes migration, demonstrate that exhibits better performance than other state-of-the-art terms achieved reduction both communication cost.
