The benefits of the ubiquitous caching in information centric networking (ICN) are profound; even though such features make ICN promising for content distribution, but it also introduces a challenge to content protection against the unauthorized access. The protection of a content against unauthorized access requires consumer authentication and involves the conventional end-to-end encryption. However, in ICN, such end-to-end encryption makes the content caching ineffective since encrypted contents stored in a cache are useless for any consumers except those who know the encryption key. For effective caching of encrypted contents in ICN, we propose a secure distribution of protected content (SDPC) scheme, which ensures that only authenticated consumers can access the content. SDPC is lightweight and allows consumers to verify the originality of the published content by using a symmetric key encryption. SDPC also provides protection against privacy leakage. The security of SDPC was proved with the Burrows–Abadi–Needham (BAN) logic and Scyther tool verification, and simulation results show that SDPC can reduce the content download delay.
 The current internet architecture is inefficient in fulfilling the demands of newly emerging internet applications. To address this issue, several over-the-top application-level solutions have been employed, making the overall architecture very complex. Information-centric-networking (ICN) architecture has emerged as a promising alternative solution. The ICN architecture decouples the content from the host at the network level and supports the temporary storage of content in an in-network cache. Fundamentally, the ICN can be considered a multisource, multicast content-delivery solution. Because of the benefits of network coding in multicasting scenarios and proven benefits in distributed storage networks, the network coding is apt for the ICN architecture. In this study, we propose a solvable linear network-coding scheme for the ICN architecture. We also propose a practical implementation of the network-coding scheme for the ICN, particularly for the content-centric network (CCN) architecture, which is termed the coded CCN. The performance results show that the network-coding scheme improves the performance of the CCN and significantly reduces the network traffic and average download delay. As a novel network architecture, Information-Centric Networking(ICN) has a good performance in security, mobility and scalability. Although in-network cache used in ICN can effectively solve the problem of network congestion. Meanwhile, it also brings a lot of challenges such as copyright protection. How to prevent unauthorized user access to the large-sized contents of the route has become the focus of the research. Some of the current solutions are based on the traditional encryption technology. But these solutions don't applay to ICN. Current approaches that rely on a common encryption key among authorized users cannot protect copyright well since if authorized user leaks the private key out, we cannot tell who has leaked the key out. In this paper, we use a novel scheme to solve the problem of copyright protection. In this scheme, we take the method of the network encoding. The first, we have splitted the large-sized content into N blocks. Then through linear network coding(LNC) encrypted the content, if the user can not obtain the decrypted matrix, the user will not be able to decrypt the content. Therefore, the scheme can achieve the protection of the content. Our analysis of this program shows that the scheme has a good performance in copyright protection.
