摘要：Cloud Computing is evolving as future generation architecture for computing. Usually cloud computingis defined as a grouping of computing recourses accessible via internet services. Traditionally the client/user store datain data centres with firewall and other security techniques used to protect data against intrudes to access the data. Theclient/user has less control over the stored data on the cloud, since the data is stored anywhere across the globe. It is theresponsibility of cloud service providers to protect the client/user data from unauthorized access & disclosure and befaithful for the development of cloud computing. A third party auditor (TPA) can be used to provide security servicesover the cloud and ensures client/user that his/her data is secure from unwanted and suspicious activity. The TPAwould not store any kind of data at its end, and it is only confined to providing security service between cloud serviceprovider and the user. During migration of data from one cloud to other cloud, the application framework will providedata integrity verification by using hashing algorithm like SHA-1 and provide encryption/decryption using symmetricalgorithm like AES. We have proposed a secure mechanism to secure data migration between clouds using third partyauditor (TPA).The proposed approach adapts the secure socket layer (SSL) protocol to increase the level of trust andsecurity for both user and cloud service provider. Network simulation tool (NS-2) is used to analyze the fairness of thechannel during data migration between clouds in terms of block encryption/decryption time duration. Our proposedmechanism improves the time constraint parameter for migrating data from one cloud to other.
