A method of generating a practically unlimited number of quasigroups of a (theoretically) arbitrary order using the computer algebra system Maple 7 is presented. This problem is crucial to cryptography and its solution permits to implement practical quasigroup-based endomorphic cryptosystems. The order of a quasigroup usually equals the number of characters of the alphabet used for recording both the plaintext and the cipher text. Moreover, it can be used for varied information viz. text, image, etc. Many of the on going algorithms uses NLFSR to generate pseudo random sequence and thus the suggested method can be integrated in any of the existing pseudo random sequence to further enhance their complexity. The implementation of PRSG using quasi group processing is highly scalable and fairly unpredictable. It has passed all publicly available random sequence generator tests. That is exactly what this paper provides: fast and easy ways of generating quasigroups of order up to 256 and a little more.Keywords

This paper implements some of the widely used symmetric encryption techniques i.e. data encryption standard (DES), triple data encryption standard (3DES), advanced encryption standard (AES), BLOWFISH and RC4 in MATLAB software. After the implementation, these techniques are compared on some points. These points are avalanche effect due to one bit variation in plaintext keeping the key constant, avalanche effect due to one bit variation in key keeping the plaintext constant, memory required for implementation and simulation time required for different message lengths.Keywords
