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.

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 ...

A block diagram of the AES engine is shown in figure 2. Fig. 2: The Xtensa processor extended with AES cipher functionality. Figure 2 shows an Xtensa processor block diagram, configured and extended ...

Unlike traditional Cipher Block Chaining (CBC) modes, the Fast Cipher Block Chaining (FCBC) method, which is derived from CBC, reduces the encryption time per block by 15% to 25%.
