Novel cryptography using Horse Step Algorithm for more flexible key

Cryptography is the art and science of securing message so unintended audiences cannot read, understand, or alter the message. Some of cryptography that has been proposed such as DES, 3DES, and AES use mathematical operation to scramble block or part of block message to encrypt. The important thing to secure message in cryptography is a key. They use variable fixed-length of key to keep the security of message. We propose novel method of cryptography, “Horse Step Algorithm”. Such algorithm exploits 2 dimensional matrix for scrambling message bit by bit. We propose two kind of keys to make it more secure. The key that we are proposing are flexible and very easy to make which can be in the form of numbers, texts, or sentences. It is very easy to make a key. By implementing this algorithm, we get flexibility of the key and excellent security. In Analysis we compare it with RSA, DES, 3DES and AES algorithm.
