Abstract
Cloud computing brings great challenges in the field of data security and security assurance. In this paper, we are analysing the different types of cloud security issues. The key and signature are generated using the elliptic curve cryptography algorithm and Ron Rivest, AdiShamir and Leonard Adlema algorithm to provide efficient security. Dynamic Merkle hash tree is constructed for providing dynamic data integrity. Public auditing is performed using Third party auditor (TPA). Checkpoint information is used for recovering the lost data blocks in the cloud storage. The main objective is to provide public auditing and data recovery to recover the lost data from the cloud storage and finally compare the key size, time taken for key generation and signature generation of ECC and RSA encryption algorithm.
