在分析现有的数据处理策略的基础上,将经过改进的基于二进制Goppa编码的McEliece密码体制与数据份额的产生相结合,提出了一种基于纠错码密码体制的数据分离算法(KPDA)。与经典秘密共享算法相比,该算法具有同等或更高的效率;而与同类的数据分离技术相比,基于编码的密码体制可以提供更好的安全保障。
The data processing before storing is a key technology of network storage systems.The main content of data processing is to reach a secure level and maintain its high efficiencies.After analyze the existed data processing policies,a new algorithm KPDA based on error-correcting code cryptography is presented.It combines data sharing generation with McEliece cryptography briny Goppa codes.The algorithm takes both efficiencies and security into consideration.It can offer even or better efficiency than classical secret sharing schemes,and offer better security than normal data dispersal algorithms.
