A new symmetric block cipher based on key-dependent S-boxes
Marcin Niemiec, Łukasz Machowski · 2012
In this paper a new symmetric cryptographic algorithm which uses new S-boxes during the encryption process is proposed. The cipher ensures high-level of confidentiality due to key-dependent S-boxes. Additionally, a new method of generating S-boxes, one of the basic and commonly used cryptographic function is presented. The method is based on the Rijndael S-box that is currently used in the AES algorithm. Nevertheless, the method is more general and it can be based on any S-box.
