摘      要：Because of its closeness to users,fog computing responds faster than cloud ***,it has been deployed to various applications,such as healthcare ***,to ensure the secure communication of the fog-based healthcare system,Jia et *** an authenticated key agreement ***,in view of the high computation cost existing in Jia et al.’s scheme,Ma et *** an efficient one using elliptic curve *** this paper,we observe that both the two schemes may potentially risk ephemeral key compromise attacks and need ***,to overcome this potential risk,we propose a new authenticated scheme based on Jia et al.’s scheme using elliptic curve computational Diffie-Hellman hypothesis and hash ***,we provide provable security under the adopted adversarial model and ProVerif simulation,and also analyze the performance in terms of computation and communication costs by *** analysis results show that the improved scheme resists the common attacks,reduces computation overhead,and has a certain significance.
