Security and QoS in Packet-Switched Networks

IP is today's dominant networking protocol. Newer version of this protocol is expected to be used in the next generation wire and wireless networks. However, the lack of quality of Service (QoS) and data security are the two major shortcomings of the IPprotocol. Unauthorized data or resource access on IP networks has been facilitated by the lack of these services. Trlokom proposes to develop a system that integrates data security and QoS. Our system will use dedicated hardware to improve thecryptographic data processing to the wirespeed. Strong authentication of the data packets transmitted over the network will form a natural defense against the network based attacks, such as the DoS attacks. The APIs for RSVP and Differentiated Services(DS) will be used to provide QoS for the applications. The QoS and security support in our system will ensure proper functioning of the applications even when the network is under an attack. Our proposed system can also be used for building interactivevideo applications, virtual private networks (VPNs), and multi-level security systems at a low cost. At the end of Phase I, we will deliver an architecture to provide security and QoS to the applications in the IP networks.A security system with QoS andhardware crypto accelerator can be used for variousapplications, such as virtual private networks, multi-level security system, multi-media multicast etc. This system will provide end-to-end security and QoS thatis easy to use at a reduced cost.
