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 ...

Abstract: Cipher algorithm identification is a crucial prerequisite for cryptanalysis, aiming to infer the encryption algorithm solely from ciphertext. Existing methods often rely on single ...

This repository implements basic implementations of AES128 and AES256 in C, Python. The core algorithm proceeds by performing S-box, shift, mix, and add_round methods. sub_bytes(state, sbox); ...

Cryptology is one of the most important techniques in the field of information security, which provides an abundance of services including privacy, data integrity, authentication, access control, ...

Sony announced late last week that they have invented a new encryption mechanism known as "CLEFIA," a block cipher algorithm designed to help content producers deliver "advanced copy protection" with ...

A formula used to turn ordinary data, or "plaintext," into a secret coded message known as "ciphertext." The ciphertext can reside in storage or travel over unsecure networks without its contents ...

We are developing custom cryptographic modules for potential clients located in South Korea. These include block cipher algorithms such as SEED, ARIA, HIGHT, and LEA. For ECB mode, both the SEED and ...
