摘要：Many storage servers are required for storage of data in Cloud storage system. Data confidentiality isimportant for the data stored in Cloud storage system. General encryption schemes available before provided securityfor the data to limited extent but failed to provide security in trustworthy manner and are costly. Central authority isrequired for constructing a secure distributed storage system and is challenging task in case of unavailability of centralauthority. Hence in this paper, we propose a formulation of secure distributed storage system by introducing a proxy reencryptionscheme which is integrated with decentralized erasure code. The aim of the proposed scheme is that itsupports encoding operations over encrypted messages. Thus provide security for the data at rest in cloud.
