Pseudonym Authentication on Network Layer in Information-Centric Networks*

摘要

The current data-centric security architecture for the Information Centric Network (ICN) does not provide efficient user authentication mechanisms, thus causing undesirable issues such as interest flooding a ttacks (IFA). I no rder to address them, this paper proposes a pseudonym authentication scheme on network layer based on the system of identity-based cryptography (IBC). In the proposed approach, each consumer needs to be authenticated before sending Interest packets into the network. After successful authentication, the consumer will be assigned a temporary nickname to be used in later data request. During the procedure, IBC is adopted to protect real names of consumers and verify the interest origin. As a result, this approach can complete user authentication and protect his real identity simultaneously. The proposed approach is case studied in IFA depression and expected results are achieved.
