Topic: Enhancing NDN Security: Name Signature Lookup System

Abstract：

Named Data Networking (NDN) is content-centric networking, where the publisher of the packet signs and encapsulates the data packet with name-content-signature encryption to verify its authenticity and integrity of itself. This scheme can solve many of the security issues inherently compared to IP networking. NDN also supports mobility since it hides the point-to-point connection details. However, an extreme attack takes place when an NDN consumer newly connects to a network. A Man-in-the-middle (MITM) malicious node can block the consumer and keep intercepting the interest packets sent out so as to fake the corresponding data packets signed with its own private key. Without knowledge and trust in the network, the NDN consumer can by no means perceive the attack and is thus exposed to severe security and privacy hazard. In this scenario, we proposed the Name Signature Lookup System (NSLS) and corresponding Name Signature Lookup Protocol (NSLP) be introduced to verify packets with their registered genuine publisher even in an untrusted network with the help of embedded keys inside the Network Interface Controller (NIC), by which attacks like MITM is eliminated. A theoretical analysis of comparing NSLS with the existing security model is provided. Digest algorithm SHA-256 and signature algorithm RSA are used in the NSLP model without specific preference.
