Security and reliability are crucial requirements of modern information systems. Therefore, appropriate error detection mechanisms are necessary, in particular in systems processing confidential or private information, i.e. modern encryptors. This paper discusses error detection in software and hardware encryption. Cryptography basics, error detection algorithms and concurrent error detection methods...
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...
