Achieving Data Integrity in Cloud Storage Using BLAKE Hash Function
Hitesh D. Patel,  Ms. Parin V. Patel,  Kiran Patel
In Cloud computing data security is biggest problem. Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage applications and services) .User can store their data remotely without maintaining local copy of data. So the integrity verification of the data is major problem in cloud storage. There is issue of security and privacy of data storage because cloud provider is not completely trusted. Integrity Verification can be managed by the use of TPA (Third Party Auditor) or without TPA. In this paper I apply integrity check without using TPA and use cryptographic hash function BLAKE to generate the signature of file or massage. It is more efficient then other hash functions like md5, SHA-1, SHA-2 and SHA-3. I use more efficient Cryptographic encryption algorithm RSA, AES and DES is more secured and faster. So this proposed model achieves storage correctness, Data Confidentiality, Authentication, Integrity and Efficient Data Access (Sharing of file) in cloud’s dynamic nature for maintaining low computation and communication cost.
