Implementation and Investigation of AES, DES and Triple DES to Secure MPLS Network

Today's communication networks and services are migrating to a converged paradigm centered on IP (Internet Protocol). MPLS (Multi-Protocol Label Switching) has emerged as a key enabling technology for this migration. MPLS technology has proven its value for delivering new services while at the same time allowing migration from old to new networks. So, the security of this network is the main important challenging task. For this, various encryption standards are used. The two main characteristics that identify and differentiate one encryption algorithm from another are its ability to secure the protected data against attacks and its speed and efficiency in doing so. This paper provides a performance comparison by implementing three of the most common encryption algorithms: DES, 3DES, and AES on MPLS Technology. This comparison has been done on different hardware machines against Brute Force Attack. Then, it finally investigates the effectiveness of these algorithms against brute force attack on MPLS Network. Simulation has been conducted in MATLAB.
