Implementation of New Cryptographic Encryption Approach for Trust As A Service (TAAS) in Cloud Environment

The cloud security and trust management is a important issue in cloud environment. Cloud computing is the result of an evolution of the widespread adoption of virtualization, serviceoriented design, involuntary and utility computing. Today, cloud computing is the fastest growing technological buzzword and captures the service-oriented market in the world, so cloud computing service providers and cloud computing consumers need to maintain a trust between them. In cloud security, if discuss security procedures of conventional IT information systems, designing security into cloud software during the software development lifecycle can greatly reduce the cloud attack surface. With cloud computing providing SAAS, secure software is a significant issue. From the cloud customer point of view, using SAAS in the cloud decreases the demand for secure software development by the customer. The requirement for secure software development is transferred to the cloud provider. In this paper, propose a new algorithm for cloud environment security and trust management using a cryptosystems methodology, which is based on the concept of a poly-alphabet cipher, an improvement over the mono alphabet. The encryption and decryption applied on plain text to cipher text and cipher text to plain text conversions. In this work, also present Power consumption, Throughput for Encryption and Decryption, and Security analysis of the algorithm.
