Cloud computing is very latest technology which is widely used now-a-days. There are many security threats in this network. Encryption is the only effective way to maintain the privacy and which provides the security in cloud computing. AES encryption algorithm takes a lot of time for computations. So a novel technique has proposed based upon KAMAN filters. In this paper, KAMAN filtering scheme is used to provide security to the cloud so that attacker will unable to hack the information.
