去中心化的安全分布式存储系统
Decentralized Secure Distributed Storage System
摘要
Abstract
This paper proposes the decentralized secure distributed storage system. The privacy of data is fulfilled by the combination of public key system and symmetric key system. Symmetric key for data from different sources are different, hence encryptions can be implemented in a distributed way. The employment of decentralized erasure code, together with the distributed encryptions, makes possible the decentralization of the system. RS codes are used to store the encryption of symmetric keys, and the list decoding of RS codes ensures the robust. Analysis result shows that the computing efficiency of this system is higher.关键词
