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: To address issues in security & the threat posed to the DES algorithm by brute force cracking, as well as the low efficiency of the 3DES algorithm, I propose extending the length of the DES ...

Based on the analysis of the principle of DES encryption algorithm, the relativity between the generation ... the methodology of preferential resources is adopted. For the round-function, the pipeline ...
