摘　　要：现今人与人之间传输数据时越来越依赖于3G移动通信网络,特别是第三代移动通信网络(3G)。尽管3G网络实现了网络组件内数据的机密性、完整性,但它并不提供用户端到端的机密性和完整性,而端到端加密的关键是有效地管理每一个密钥。因此文章提出了一种新的端到端加密的密钥管理方案,该方案基于三方Diffie、Hellman密钥协议算法,充分利用了3G的特殊性,只增加一种新的软件,几乎没有改变3G的物理结构。文章还对方案进行了评估,证明了该协议能够提供消息的机密性,以及通信双方双向认证的正确性。Nowadays interpersonal transmission of data rely more and more on the 3G mobile communication network,especially the third generation mobile communication network（3G）.Although the 3G network realization within the network components of data confidentiality and integrity,but it does not provide the user＇s end-to-end confidentiality and integrity,and end-to-end encryption is key to how to effectively manage every key.Therefore this paper proposes a novel end-to-end encryption key management scheme,which based on tripartite diffie-hellman key agreement algorithm,fully utilize the particularity,besides 3G added a new software outside,hardly changed the physical structure of the 3G.This paper also evaluated for scheme,prove that this agreement can provide news of confidentiality,and the correctness of the two-way communicating parties authentication.
