Access Control Supported by Information Service Entity in Named Data Networking

Named Data Networking (NDN) has been viewed as a promising future Internet architecture. It requires a new access control scheme to prevent the injection of unauthorized data request. In this paper, an access control supported by information service entity (ACISE) is proposed for NDN networks. A trust entity, named the information service entity (ISE), is deployed in each domain for the registration of the consumer and the edge router. The identity-based cryptography (IBC) is used to generate a private key for the authorized consumer at the ISE and to calculate a signature encapsulated in the Interest packet at the consumer. Therefore, the edge router could support the access control by the signature verification of the Interest packets so that no Interest packet from unauthorized consumer could be forwarded or replied. Moreover, shared keys are negotiated between authorized consumers and their edge routers. The subsequent Interest packets would be verified by the message authentication code (MAC) instead of the signature. The simulation results have shown that the ACISE scheme would achieve a similar response delay to the original NDN scheme when the NDN is under no attacks. However, the ACISE scheme is immune to the cache pollution attacks so that it could maintain a much smaller response delay compared to the other schemes when the NDN network is under the attacks.
