Abstract

Cryptography plays an important role in secure communication systems. It becomes extremely used in many applications such as wireless technology, online billing, e-business, secure log in, emails, etc. The encryption algorithm is used in cryptography to generate and encrypt a key in a block cipher. However,  a key dependent  process is needed to make cryptanalysis attacks  are difficult to discover the key in a block cipher. In this paper, a key dependent S-Box approach is reviewed to improve the security of a cryptosystem.  The study found that, a key dependent S-Box in a block cipher is more secure and efficient compare than static S-Box. As a result, a new approach of key dependent S-Box is needed to build more secure block ciphers based on performance and strong cryptanalysis.
