Randomly encrypted key generation algorithm against side channel attack in cloud computing

Cloud computing offers both services that provide resources over the Internet and economic benefits for using these resources. Economic benefit plays a vital role both for users and providers of cloud. The users pay as they use on the other hand resources of providers never remain idle. The cloud users hive away their valuable data in the cloud and perform their activity with the data. The security of these valuable data should be ensured. The side channel attack is one of the common attacks in cloud computing. Attackers use a malicious virtual machine to retrieve data from the cloud. In this paper, implements a randomly encrypted key generation algorithm against side channel attack in cloud computing. As anyone can use the cloud, it makes easy for the attackers to attack the desired users data. Also, a process has been developed that generates random keys to encrypt data of the cloud users at the time of storage and transmission. The attackers may find the encrypted data when they grab the users data that may no further value for them.
