Cloud is a large group of interconnected computers, which is a major change in how users store information and run application. Cloud computing is a technology and large - scale computing resources to effectively integrate, and the resources are computed based on cryptographic secure hash functions. The biggest problem of one time signature scheme is the key management. An efficient key management is needed to make one-time signature scheme and the Merkle signature schemes feasible. This paper presents detailed study on one-time signature and Merkle signature schemes.
