MISTY系列分组密码及其在3G移动通信安全中的应用

The MISTY Series Block Cipher and Its Application in the 3G Mobile Communication Security

介绍了MISTY1,MISTY2&KASUMI分组密码算法的原理、组成部分及流程;分析了算法的安全性和优缺点;阐述了以KASUMI算法为核心的3GPP安全机制中的数据加密,以及信令完整性保护标准化算法f8和f9。

In this paper, the principle, components and flow of the MISTY1, MISTY2 ＆ KASUMI block cipher algorithms are introduced, and the algorithms＇ security and relative merits are analyzed. Finally, The standardized f8 ＆ f9 algorithms based on the KASUMI in the 3G security mechanism are formulated.
