安全网络并行计算环境SNPCE

Secure Network Parallel Computation Environment(SNPCE)

由于网络并行计算环境建立在飞速发展的互联网上,容易受到各种黑客攻击,而目前各种流行的并行计算环境都没有提供完整的安全保护机制,因此,建立一个安全的网络并行计算环境,将并行程序设计人员从复杂的安全防范措施中解脱出来成为一个非常重要的研究方向。该文针对网络并行计算环境可能遭受的各种攻击,设计并实现了一种综合利用认证、加密、签名、消息摘要等多种安全防范手段的安全网络并行计算环境SNPCE系统。该系统能对其用户提供透明的安全防范措施,极大地减轻了并行程序设计人员的负担,同时也大大增加了系统对抗各种攻击的健壮性。

With the speedy development of Internet,the parallel computation environments based on it are prone to be attacked.At the same time ,none of the existing NPCEs provides complete security mechanism.Thus,constructing a secure network parallel computation environment becomes very important because it can release the parallel programmers from a lot of complex designs and implementations to resist various attacks.This paper analyzes various network attacks and designs a secure environment SNPCE to resist those attacks.In this environment ,authors utilize various secure methods,including encryption,signature,verify,authentication,timestamp ,etc.So,it can provide security transparency,enhance the system robustness and lighten the burden of parallel programmer.
