AbstractThe Symmetric Block cipher is a considerable encryption algorithm because of its straightforwardness, rapidity and strength and this cryptographic algorithm is employed in carrying out the encryption and decryption for most current security applications. The confusion properties are attained using the substitution-Box (S-Box). Substitution and permutation functions are normally used in block ciphers to make them much firmer and more effectual ciphers. The Security of S-Box is checked using S-Box test criteria and the randomness test. The objective of this paper is to give the researchers a specific knowledge (standards) for testing the ciphers’ S-Boxes. This paper includes survey or guide for the S-box test criteria.
