Efficient and Secure Dynamic Auditing Protocol for Integrity Verification In Cloud Storage

Priyanga.R, Maheswari.B, Karthik.S

In cloud computing, information homeowners host their information on cloud servers and users (data consumers) will access the information from cloud servers. As a result of the information outsourcing, however, this new paradigm of knowledge hosting service additionally introduces new security challenges, which requires associate freelance auditing service to ascertain the information integrity within the cloud. Some existing remote integrity checking strategies can solely serve for static archive information and, thus, can't be applied to the auditing service since the information within the cloud are often dynamically updated. Thus, economical and secure dynamic auditing protocol is desired to convert information homeowners that the information area unit properly holds on in the cloud. Economical and privacy-preserving auditing protocol was proposed to provide data integrity. Then, this scheme extends the auditing protocol to support the information dynamic operations, that is economical and incontrovertibly secure in the random oracle model. Also auditing protocol supports batch auditing for each multiple homeowners and multiple clouds, without exploitation any sure organizer. The analysis and simulation results show that projected auditing protocols area unit secure and efficient, particularly it scale back the computation value of the auditor.
