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 ...

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 ...

For decades, a quiet intuition shaped how engineers approached the Generalized Feistel Network — the multi-branch block cipher architecture behind Sony's CLEFIA, the international lightweight ...

Cryptography is one area of information security that is well known but often not well understood. The basics of the algorithms may stay the same, but as attacks and infections evolve, so too must the ...

Understand the crypto concepts behind the modern internet security infrastructure, from digital signatures and transport layer security to blockchains and Bitcoin. Cryptography grows ever more ...

There’s little doubt that some of the most important pillars of modern cryptography will tumble spectacularly once quantum computing, now in its infancy, matures sufficiently. Some experts say that ...
