Abstract

Rijndael algorithm was selected as the advanced encryption standard in 2001 after five year long security evaluation; it is well proven in terms of its strength and efficiency. The substitution box is the back bone of the cipher and its strength lies in the simplicity of its algebraic construction. The present paper is a study of the construction of Rijndael Substitution box and the effect of varying the design components on its cryptographic properties.
