Abstract: Cloud computing offers utility -oriented IT services to users. Cloud computing provides us cheaper, faster, flexible, efficient environment. Cloud computing provides multitudinous benefits to both service provider and customer. A fresh look at the way secure communications is currently being done has been undertaken as a consequence of the large hacking's that have taken place recently.Due to large advancement many companies are migrating to cloud environment. However, the security of cloud computing has been a challenging one. DNA cryptography is used to encrypt message for secure communication on cloud computing environment. Protecting sensitive data is challenging task in cloud environment. For increased security, the recommended approach is to combine two or more methods – processes, DNA cryptography and Morse pattern. DNA cryptography with Morse pattern is difficult to fabricate, which makes the attacker much harder to steal the original data. Use of Morse code and Zigzag pattern makes the attacker much harder to steal original data. Furthermore, the proposed scheme is implemented and the accuracy of encryption and decryption of data is verified.
Keywords: Morse code, DNA sequences, Cloud Computing, Morse Pattern, Zigzag Pattern, Data Block Security, Encryption, Decryption, Key Rotation.
