摘要
研究了安全网关中算法的实现。首先介绍了安全网关的基本功能框架分析了选择基于硬件的解决方案的必VPNIDEADSPVPN, DSP要性;其次介绍了的特点与功能,并对加密与解密算法进行了分析与描述;最后提出了算法的实现方案。
The implementation approach for IDEA encryption algorithm based on DSP in the secure VPN gateway is studied in this paper. Firstly, the basic functional framework of SVPN gateway is introduced. The necessity for choosing the solution-based DSP hardware is discussed. Furthermore, the characteristic and function of the DSP chip are illustrated. IDEA algorithm is analyzed and described. Finally, the DSP implementation method for IDEA is put forward.
