Data Ancryption Standard (DES) Overview The Data Encryption Standard (DES) is a symmetric-key block cipher developed at IBM in the 1970s. As a symmetric algorithm, it utilizes the same key for both encryption and decryption. Although largely superseded by the Advanced Encryption Standard (AES) due to its relatively short key length, DES remains ...

Introduction Lattice basis reduction is a fundamental problem in mathematics and computer science with wide applications in cryptanalysis, post-quantum cryptography, and integer programming. As quantum computing advances, traditional number-theoretic cryptographic systems face vulnerability risks, making lattice-based cryptography an important ...
