A comprehensive performance benchmarking suite for symmetric block ciphers using the OpenSSL EVP API. Built as part of the CT4104 Computer & Network Security course. This project measures and compares ...

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, ...

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 ...

In the previous blog post, “Embedded Security Using Cryptography”, we looked at how cryptography can be used for securing assets in embedded systems and ensure confidentiality, integrity and ...
