摘　　要：为了解决社交网络(SNS)易遭受中间友人攻击的缺点,提出了一个新协议,通过结合异或(XOR)编码,并引入杂凑函数、消息认证等密码学机制,使得提出的协议简单易行且为轻量级。通过安全性分析和计算量分析,证明该协议能够有效地抵抗中间友人攻击和重放攻击,同时较大程度降低计算量,节省存储空间。In order to resist friend-in-middle attack in Social Networks（SNS）, a new protocol is proposed to solve above issues. Combined with Exclusive OR（XOR） coding, cryptology schemes of hash function and message authentication, the protocol is easy to be carried out and light-weighted. Through security and computing overhead analysis, the protocol has been proved to be efficient in resisting friend-in-middle attack and replay attack, as well as largely reducing computation overhead, cutting down the storage space. As other protocols at present can not efficiently solve above issues, the new one is evidently advanced and applicable.
