A QUADRUPLEX DATA ENCRYPTION SCHEME TO SECURE CLOUD DATA

In cloud computing security of the sensitive data is a great concern. In this respect, several encryption schemes were proposed to provide high security from the threat of attacker. But due to the rapid growth of software technology the security algorithms become easily breakable. To increase the security, the recommended approach is to combine two or more cryptographic methods. In this paper, a four layer security scheme is proposed using RSA, DNA sequence and Morse pattern which prove to provide high security that is quite impossible to hack. Thus makes the scheme highly efficient for cloud environment.
