Developing a multidimensional algorithm for encryption and decryption

Cryptography is the discipline which embodies principles, means, and methods for the transformation of data in order to hide its information content, prevent its undetected modification and/or prevent its unauthorized use. In cryptography, encryption is the process of transforming information (referred to as plaintext) using an algorithm (called cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. Symmetric algorithms are attractive due to 1000 times faster than asymmetric one and easy to implement. Symmetric algorithms or secret key algorithms keeps the key secret and shared by two authorized parties. Although in the existing system a multidimensional scheme was working but the existing scheme was not giving the security to small data In this paper we have increased number of rounds in order to perform encryption. This process makes encryption stronger and result in higher security of larger text too.
