Abstract:
Data integrity and privacy become major problems that the customers concern when the data is stored in the cloud storage.The paper proposes a novel oblivious RAM construction that achieves O(1)time complexity of access cloud storage,while consuming O(cN)(0<c<1)client-side storage and O(N)server-side storage.The paper proposes a technique in which the client data is stored in two servers that each server has a client data copy in order to ensure data integrity.Oblivious RAM allows a client to hide its data access patterns from an untrusted server.The adversary can not obtain useful information from the client access pattern,and the data privacy is guaranteed.
