摘要
针对异构无线网络中的域间垂直切换,提出一种基于可信第三方的切换认证和密钥协商协议,协议分别考虑了向上切换和向下切换两种切换场景.文中还改进了一种三方密钥分配协议,用于实现域间垂直切换认证过程中的临时密钥分配.分析比较表明,该方案在安全和性能上具有较好的折中性.
One of the main characteristics of heterogeneous wireless network convergence is inter-domain vertical handover (VHO). The authentication and key agreement is the key to successful inter-domain VHO. Focusing on the inter-domain VHO of heterogeneous wireless network, a trusted third-party (TTP) based handover authentication and key agreement protocol was proposed. Two handover scenarios were considered in the protocol, namely upward VHO and downward VHO. Also a three party key distribution protocol was improved and used to distribute the temporary key during inter-domain VHO. The analysis and comparisons show that the protocol is a good trade-off between the security and performance.
