Effective Caching for the Secure Content Distribution in Information-Centric Networking
This addresses secure content distribution for ICN users, but it appears incremental as it builds on existing encryption and caching methods.
The paper tackles the problem of ineffective caching of encrypted content in Information-Centric Networking (ICN) by proposing the Secure Distribution of Protected Content (SDPC) scheme, which ensures only authenticated consumers can access content and was verified using BAN logic and Scyther tool.
The secure distribution of protected content requires consumer authentication and involves the conventional method of end-to-end encryption. However, in information-centric networking (ICN) the end-to-end encryption makes the content caching ineffective since encrypted content stored in a cache is useless for any consumer except those who know the encryption key. For effective caching of encrypted content in ICN, we propose a novel scheme, called the Secure Distribution of Protected Content (SDPC). SDPC ensures that only authenticated consumers can access the content. The SDPC is a lightweight authentication and key distribution protocol; it allows consumer nodes to verify the originality of the published article by using a symmetric key encryption. The security of the SDPC was proved with BAN logic and Scyther tool verification.
