摘要
针对IMS网络合法实体被劫持后可能以中间人攻击原理实施攻击行为的安全威胁,提出了一种基于动态验证码的身份验证机制,该机制能够有效地验证通信过程中的各实体,并设计了实体相应的存储表。最后给出了该机制防护效果的分析,通过搭建IMS网络仿真环境验证了其有效性。
In order to eliminate the threat of the attacking actions from legal entities which are hijacked and to use the intermediary principle in IMS, this paper proposes an identity authentication mechanism based on dynamic verification code, which can verify the entities effectively. Then it de- signs the tables of storage for each entity. Finally, it gives the analysis of this defending technology. Simulation results demonstrate the validity of this new mechanism.
