Cloud computing is the apt technology for the decade. It allows user to store large amount of data in cloud storage and use as and when required, from any part of the world, via any terminal equipment. While cloud services offer flexibility, scalability and economies of scale, there have been commensurate concerns about security. On the similar terms, the authors have chosen to make use of a combination of authentication technique and key exchange algorithm blended with an encryption algorithm. In this paper, they have proposed to make use of 3DES algorithm which is a well-known symmetric cryptosystem.
