shifted to the left by the factor of the current round, and then XORed together. The 16-bit output is then expanded to 32 bits using an expansion function. This algorithm is inspired by DES. The input ...

The Data Encryption Standard (DES ) is a symmetric-key algorithm for the encryption of electronic data. Although insecure, it was highly influential in the advancement of modern cryptography. The ...

Abstract: The Data Encryption Standard (DES) was a widespread symmetric key block cipher algorithm. It was the most popular used cryptographic scheme. DES's security was a highly contentious and ...

functions, namely signing & verifying, and the last is the 3DES algorithm as double security which guarantees 3 (three) times the encryption process and description. By implementing a digital ...
