A New Approach towards Encryption Schemes: Byte - Rotation Encryption Algorithm

Information security is a challenging issue in today's technological world. There is a demand for a stronger encryption which is very hard to crack. Earlier many researchers have proposed various encryption algorithms such as AES, DES, Triple DES, RSA, Blowfish etc. Some of them are most popular in achieving data security at a great extent like AES and Blowfish. But, as security level is increased, the time and complexity of algorithm is also increased. This is the major cause of decreasing the speed and efficiency of the encryption system. In this paper we have proposed a new encryption algorithm Byte - Rotation Encryption Algorithm (BREA) with Parallel Encryption Model which enhances the security as well as speed of the encryption scheme. The BREA is applied on different blocks of plaintext and executes in parallel manner through multithreading concept of single processor system. This paper is an attempt to invent a new encryption model which is secure and very fast.
