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 ...

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 ...

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, ...

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 ...

The tee_do_cipher_update() function in core/tee/tee_cryp_utl.c contains incomplete validation logic for the SM4-CTR algorithm. This causes potential failures for SM4-CTR cipher operations when ...

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 ...
