Ensuring Content Integrity and Confidentiality in Information-Centric Secure Networks
Htet Htet Hlaing, Hitoshi Asaeda · 2023
Information-centric networking (ICN) brings in-network caching as a significant characteristic along with its novel network architecture. In-network caching serves as an efficient content distribution strategy in which intermediate routers store and redistribute data to reduce network latency, congestion, and retrieval time. Meanwhile, it decouples contents from the publisher, and content integrity and confidentiality turn out to be problematic. In this study, we propose a mechanism named “in-network secure content management” (ISCM) to facilitate content integrity and authenticity in ICN by exploiting identity-based cryptography (IBC) for content signature verification. In addition, it guarantees content confidentiality by applying a hybrid encryption-based access control mechanism to prevent unauthorized content access and tampering attacks. Evaluation results reveal that ISCM offers secure content retrieval in ICN with a scalable key distribution without significant computational overhead and communication delay.
