Secure Multimedia Content Retrievals via Multi-path Transmission in Named Data Networking

Named Data Networking (NDN), as a typical implementation for Information-Centric Network (ICN), has been introduced to solve some inherent problems that arise with today's TCP/IP network model and it has also been proven to have good prospects in multimedia services. Meanwhile, in the sensitive occasions, the security requirements of multimedia data transmission are higher. Due to the hacking techniques and misuse of cryptography, signed-packets can no longer be considered a safeguard from attacks. Adversaries with eavesdropping capability along a routing path can compromise the data privacy or even disconnect the end-to-end communications. So, we will propose a new way of solving the eavesdropping problem in NDN, a novel routing protocol namely multi-path content retrieval protocol(MPCRP). In our approach, we establish a new kind of multi-path forwarding table(MPFT), to establish the node-disjoint multi-path. Under the condition that no adversary obtains all pieces of privacy data, our approach can securely deliver the user privacy data against eavesdropping. The ndnSIM results demonstrate that our MPCRP achieves its design goals.
