基于MPICH并行计算系统安全通信策略研究

摘要

In order to improve the security of remote access based on SSH ( Secure Shell) , and to give consideration to the efficiency of access. Based on the principle of RSA/DSA ( Rivest Shamir Adlemen /Digital Signature Algorithm) password-free certification, three kinds of executive plan about telecommunication security of the parallel computing system based on MPICH ( Message-Passing Interface Chameleon) are put forward, which aim at the telecommunication security of the parallel computing system based on MPICH. This research can offer the plans of security and efficiency for the construction of the parallel computing system and the remote access based on SSH.%为提高基于SSH (Secure Shell)远程访问的安全性,兼顾访问的高效性,针对基于MPICH( MessagePassing Interface Chameleon)并行计算系统通信环境的安全性问题,在RSA/DSA (Rivest Shamir Adlemen/Digital Signature Algorithm)的密码认证的基本原理基础上,提出了3种基于MPICH并行计算系统安全通信的实现方案,并对其进行分析比较.为并行计算系统的构建及基于SSH的远程访问提供了安全、高效的通信方案.
