Block ciphers are invertible symmetric key cryptographic algorithms. Here, symmetric means that the same cryptographic key is used to both encrypt and decrypt messages. The key is used to transform ...

Cipher block chaining (CBC) is a mode of operation for a block cipher-- one in which a sequence of bits are encrypted as a single unit, or block, with a cipher key applied to the entire block. Cipher ...

Block ciphers, a branch of modern cryptography, are playing a more prominent role in protecting information security as 5G technology develops. Although encryption algorithms of the traditional ...

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.

Federated learning has long been pitched as the privacy-friendly way to train artificial intelligence: instead of shipping sensitive data to a central server, the model travels to the data, and only ...
