—Security being the major concern during data transfers, we have various challenges to face. The requirements of the security model vary depending on the type of data to be encrypted. Considering small size of data the requirements change from the existing security encryption techniques. One of the major issues to be considered is the computational speed of the encryption model. Though there are many challenging encryption algorithms, which provide high level of security, they increase the level of execution time for encryption. Cost effectiveness of the encryption algorithm is also another main concern for determining the efficiency of the algorithm. The computational time of the algorithms have a major impact on the determining the cost effectiveness. In this paper, we propose an enhanced cost effective symmetric key algorithm for small amount of data.
