Remote Data Integrity Checking of Identity-based Proxy in Public Cloud Environment
摘要
Abstract
Cloud computing as an alternative to conventional computing has a rapid development because it can provide a flexible,dynam-ic and resilient infrastructure for both academy and business. In public cloud environment,the clients move their data to Public Cloud Server ( PCS) . Since remote data are uncontrollable,checking its integrity is of crucial importance. It enables the clients to check whether their outsourced data have been kept intact without downloading the original data. In some cases,the clients are failed to check the integri-ty of remote data so that they have to delegate their proxy for checking of remote data integrity. Based on the bilinear pairing technique and the hardness of computational Diffie-Hellman problem,a protocol of remote data integrity checking of identity-based proxy is de-signed where identity-based cryptography system is used to reduce authentication of public key certificates and lower the storage and communication costs of user and public cloud server. Through analysis of security and performance,the protocol proposed is provably se-cure and efficient.关键词
