A security enhanced network architecture for future networks

Security is one of the most urgent problems in today\´s Internet. For the lack of a clear definition of identifier of entity we seek to manage in the Internet, existing security mechanisms are not well integrated into the Internet architecture. These security mechanisms are designed as separate extensions and their effectiveness are limited. In this paper, we present a new network architecture, Security Enhanced Network Architecture (SENA), to provide a "built-in" security. In SENA, there are four identifiers, including service identifier, connection identifier, endpoint identifier and routing identifier. With a reinforced control plane, the architecture allows network administrators directly manage the mappings between different identifiers and provides security as an integrated solution.
