Remote Data Integrity Checking Protocols from Homomorphic Hash Functions
Remote Data Integrity Checking Protocol (RDC) is an interactive protocol allowing a client to verify that a storage service provider (SSP) faithfully stores a file.Existing protocols are mainly built from homomorphic identification protocols.In this paper,we first present a RDC protocol (HH-RDC) from a homomorphic hash function.The key technique is treating the file as a set of integers other than elements in some large field in previous protocol.The proposed protocol support public verifiability,data dynamic and privacy against verifiers.We then present a variant (V-HH-RDC) of HH-RDC by fixing and simplifying some parameters.Compared with HH-RDC,V-HHRDC obtains a significant improvement in computation and communication at the sacrifice of losing feature of public verifiability.V-HH-RDC is very suitable for low-power devices,such as cell phones.After that,theoretical analysis and experimental results show that the proposed protocols have good performances.
