Point - to - Point Virtual Private Network Based on IP Filtering and Rijndael Encryption Algorithm

The Rijndael algorithm was chosen to take advantage of its features and add recent technology to increase the confidentiality and security for the transfer of sensitive data on some important institutions. Rijndael algorithm (Advance Encryption Standard) is the Encryption of Symmetric Key, each one of the keys has size of 128 bit. Each round consists of several processing steps; one of them is depend on the encryption key. Therefore NEDRO program has been designed depending on Rijndael algorithm and updated by adding the key (Initialization Vector), in addition to taking into consideration the possibilities that could face the process of transmission of data between   two sides. Finally NEDRO program has implemented and tested practically between two points (User making encryption and Host making decryption or Host making encryption and User making decryption at the same time ) Keywords : Cryptography , Rijndael (AES) ,Data Security , Encryption , Decryptio
