云计算中一种分布式缓存加密存取方法

An encrypted access for distributed cache in Cloud computing

分布式缓存是云计算系统中提高应用程序性能的重要手段,针对云计算环境中分布式缓存的隐私问题,提出一种基于中国剩余定理的轻量级分布式缓存数据加密存取方法。该方法能够保护缓存数据的机密性,防止云计算环境中的其他用户、平台提供商或者攻击者获取明文缓存数据,且能够较好地保证缓存系统的性能,最后通过实验证明了该方法的有效性。

Distributed caching is an important means of Cloud computing systems to improve application performance.In order to solve privacy issue for distributed cache in Cloud computing environment,a lightweight data encryption access methods based on Chinese remainder theorem is proposed.The method can effectively protect the confidentiality of data cache,and can prevent other users,the platform provider or attackers to obtain the plaintext data cache,with better performance.And the effectiveness of this method is proved by experiment.
