In this paper, the authors have developed a new symmetric key algorithm for encryption and decryption of data which uses a cyclic operation. With the growth of internet and network, the need for secure data transmission become more and more essential and important, as security is a major concern in the internet world. Data likely to be kept hide from all people except from the authorized user cannot be sent in plain text. So the plain text should be codified by the process of encryption. Each type of data has its own features; therefore different techniques should be used to protect confidential data from unauthorized access.
