Abstract: This chapter focuses on block ciphers, which are the most commonly used algorithms to encrypt confidential data. In addition to ciphering, block ciphers can be used as stream ciphers and ...

Abstract: In order to solve the problem of worse recognition performance under the multi-classification scenarios of existing cryptosystem identification, this paper proposes a block cryptosystem ...

Zero-correlation linear cryptanalysis is an important method to analyze the security of block ciphers. But there are few works on zero-correlation linear attacks combined with the related-key setting.

Tweakability is achieved by XORing the key with the tweak and a permutation of the key during key initialization. This is generally undesirable, for performance and security reasons. For performance, ...

The American National Institute for Standards and Technology (NIST) is rather busy on the cryptographic front these days. Not only has it been busy in the area of Post-Quantum Cryptography (PQC), it ...
