摘要

Cloud computing has revolutionized the way the data is stored, processed and made available. It has evolved in various forms of utility computing by sharing resources, infrastructures and data storage facilities and got wide acceptance because of its services and storage capacities. But security issues are a major concern in the cloud which is restricting its use among organizations which deals with sensitive data such as health care, Pharmaceuticals etc. and remain one of the greatest inhibitors for the adoption of Cloud computing if the security issues continue. For data protection, various techniques evolved through years for Ciphers, Cryptography, Steganography and recently DNA based encryption for security is the trend. DNA cryptography was a breakthrough in the field of security which uses bio-molecular concepts and gives us new hope of unbreakable algorithms but the concepts need to be exploited more especially in the cloud computing. This paper discusses cloud computing features, service models, security issues and proposes a DNA based encryption algorithm for securing data in cloud environment which will be cost effective and secure by using bio-computational techniques. The suggested algorithm uses indexing and DNA steganography techniques along with binary coding rules which make algorithm secure as it is an additional layer of biosecurity than conventional cryptographic techniques.
