Enhancement of Video Encryption Algorithm Performance Using Finite Field Z2^3-Based Chaotic Cipher

This paper discusses the use of finite field Z2^3 as the basis of bit stream encryption process with chaotic cipher. Construction of finite field Z2^3 is based on finite field Z2, algebraic concept employed in cryptography. Finite field Z2^3 has eight elements whereas Z2 has two elements. Therefore more combination of bit stream composition pattern can be achieved and robustness against known-plaintext attack is expected.
