| Abstract | ||
| Data Encryption Standard (DES) is based on a round of starters, from the results of the use of multi-stage permutation and replacement to the more complex algorithm which adopts the symmetric key. Diffie- Hellman is based key generation algorithm puts a shared secret key between two parties A and B, which depends on the prime number. This research suggest a technique it is objective is the blending between the two encryption methods DES and Diffie Hellman to make DES more safe and secure. That by propose two options first one include injection the encryption DES after the seventh round with Diffie-Hellman just as key distribution algorithm then the results of the last back to the eighth round to complete the encryption process of DES. The second include injection the encryption DES after the eighth round with Diffie-Hellman just as key distribution algorithm to generate key the results of the eighth round will be encrypted using stream cipher then back to the ninth round to complete the encryption process of DES. | ||
