Symmetric and Asymmetric cryptography algorithm for improving data security

Abstract

Abstract:Information security is the process of protecting information. It protects its availability ,privacy and integrity. Access to stored information on computer databases has increased greatly. More companies stores business and individual information on computer than ever before. Mush of the information stored is highly confidential and not for public viewing. In this paper I have developed a new cryptography algorithm which is based on block cipher concept. In this algorithm I have used logical operation like XOR and shifting operation. Experimental results show that proposed algorithm is very efficient and secured.
