摘要：A cloud is a collection of storage servers maintained by the cloud service provider. It is providing on-demand self service, resource pooling, rapid elasticity and measured service. But data confidentiality is the main problem for the users when they are storing the information in cloud. But cloud minimizes the investment cost of the individual users. Security can be provided by building a secure storage system along with two identity-based secure distributed data storage schemes. This scheme can capture the following properties: (1) The file owner can decide the access permission independently without the help of the private key generator (2) For one query, a receiver can only access one file, instead of all files of the owner. The proposed method is a proxy reencryption scheme which is integrated with a decentralized erasure code so that a secure distributed storage system is developed.
