NDN-MPS: supporting multiparty authentication over named data networking

Modern digitally controlled systems require multiparty authentication to meet the security requirements. This paper describes the design and development of NDN-MPS, an automated solution to support multiparty signing and verification for NDN-enabled applications. NDN-MPS proposes three basic changes to the existing NDN security solutions. First, it introduces a new type of trust schema that supports the semantics for multiparty singing and verification. Second, it extends the NDN signing process design to accommodate multisignature schemes such as BLS signature and to ensure the data consistency across signers. Third, NDN-MPS provides options for different application scenarios to coordinate the joint signing process of multiple signers. We evaluate NDN-MPS by assessing its security properties and measuring its performance. Our results show that NDN-MPS provides resistance against different types of attacks and is practical to be deployed.
