A Secure Identifier-to-Locator Mapping Mechanism in Smart Identifier Network

Abstract

In recent years, the rapid development of Programmable Data Plane(PDP) technology provides the possibility for the large-scale deployment of Smart Identifier Network(SINET). As a revolutionary network architecture, SINET supports terminal mobility and network extensibility natively by adopting the separation of identifier and locator. At the beginning of the SINET design, the security of the mapping information in the mapping publish/query protocol was not considered. At the same time, because of the PDP-based SINET using a separate control and forwarding architecture, the mapping information between the control plane and the data plane is more vulnerable to eavesdropping attacks and man-in-the-middle attacks.In this paper, we proposed a secure Identifier-to-Locator mapping mechanism in the PDP-based SINET. We designed a bCPA(bit-wise CPA) algorithm to protect the mapping information in the mapping publish/query protocol. We implemented the mechanism and evaluated its performance in the prototype system. The experimental results show that the method we designed guarantees the security of the mapping information without affecting the mapping publish/query performance and has less time increment compared to existing methods.
