| Abstract: The paper attempts to provide most of the well-known security services through a design and implementation of a client/server-based network security system. The system is based on recommendation of the Advanced Encryption Standard (AES) together with some secure techniques. These techniques include message digest (MD5), data compression, data scrambling, traffic padding, novel PN sequence generator that is based on AES and the RSA for secure key distribution. The generator is based on the standard ANSI X9.17 with triple AES instead of triple DES. Recommended statistical tests are carried out to check the randomness of the new generator. The results of these tests show that the new generator passes all the required tests successfully. The latter results being even better than those achieved by the standard generator ANSI X9.17 using AES or triple DES. Finally, the security system was implemented and tested between two PCs in a local area network. The results clearly demonstrate the successful operation of the security system through the secure transmission of data. The security of the proposed system is shown to be efficient since all the combined techniques are well-established and recommended. Furthermore, with the multi-keys required to perform the operation, the tasks of cryptanalyst with available computing power will be difficult. | ||
