Cloud Computing (CC) is used worldwide for accessing the Clients over the web in a pay for service only as cost estimating mode. Clients can store a lot of information in the cloud at a generally lower cost.  By putting away their information in the Cloud, the Clients can maintain a budget-oriented venture of costly framework arrangement, enormous hardware and day to day supporting cost. Due to this advantage of the cloud, it also faces numerous security testing configuration issues, which should be comprehended and settled. One of the most significant security perspectives that should be tended to guarantee was Security, Reliability and Integrity of the information put away in the cloud. Since clients don't have authority over the information, the current cryptography strategies were not guaranteeing this requirement due to technological advancement. Since clients use the public network Internet, we analyse the security provided by the recent protocols such as Homomorpic Distribution Verification Protocol (HDVP), RSA based Dynamic Public Audit Protocol (RSA-DPAP), Elliptic Curve Cryptography based Dynamic Public Audit Protocol (ECC-DPAP) and Public Verifiable Dynamic Secret Sharing Protocol(PVDSSP). In this paper, we examine the computation cost and storage cost of HDVP, RSA-DPAP, PVDSSP and ECC-DPAP security protocols for the storage of the client's data in the cloud. It is proved from the results that PVDSSP is more efficient than HDVP, RSA-DPAP, and ECC-DPAP protocols for the data stored in the cloud.
