An XOR cipher in assembly language. In cryptography, the simple XOR cipher is a type of additive cipher, an encryption algorithm that operates in binary according to the following principle: A ...

Abstract: This article is concerned with the secure state estimation problem for a networked system with multirate measurements. The measurement data are transmitted to the estimator over a ...

Apple today published new corecrypto source code on GitHub, alongside a detailed technical post explaining the intricate work behind its post-quantum cryptography efforts across iPhone, Mac, and more.

Abstract: The Caesar Cipher is one of the earliest substitution ciphers used in classical cryptography. Although historically important, it provides extremely weak security due to its small key space ...
