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: DES, 3DES, AES, blowfish, RC4, encryption, decryption, ciphertext, deciphertext, plaintext.
