Abstract
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.
