Internet architecture has transformed into a more complex form than it was about a decade back. Today the internet comprises multimedia information where services and web applications have started to shift their focus on content. In our perspective of communication systems, content-centric networking (CCN) proposes a new methodology. The use of cache memory at the network level is an important feature of this new architecture. This cache is intended to store transit details for a set period, and it is hoped that this capability will aid in network quality, especially in a rapidly increasing video streaming situation. Information-centric networking (ICN) is the one architecture that is seen as a possible alternative for shifting the Internet from a host-centric to a content-centric point-of-view. It focuses on data rather than content. CCN is more reliable when it comes to data delivery as it does not need to depend on location for data. CCN architecture is scalable, secure and provides mobility support. In this paper, we implement a ccnchat, a chat testing application, which is created with the help of libraries provided by Palo Alto Research Center (PARC) on local area network (LAN) between two users and demonstrate the working of this local chat application over CCN network that works alongside existing IP infrastructure.

In healthcare 4.0 ecosystems, authentication of healthcare information allows health stakeholders to be assured that data is originated from correct source. Recently, biometric based authentication is a preferred choice, but as the templates are stored on central servers, there are high chances of copying and generating fake biometrics. An adversary can forge the biometric pattern, and gain access to critical health systems. Thus, to address the limitation, the paper proposes a scheme, PHBio, where an encryption-based biometric system is designed prior before storing the template to the server. Once a user provides his biometrics, the authentication process does not decrypt the data, rather uses a homomorphic-enabled Paillier cryptosystem. The scheme presents the encryption and the comparison part which is based on euclidean distance (EUD) strategy between the user input and the stored template on the server. We consider the minimum distance, and compare the same with a predefined threshold distance value to confirm a biometric match, and authenticate the user. The scheme is compared against parameters like accuracy, false rejection rates (FARs), and execution time. The proposed results indicate the validity of the scheme in real-time health setups.
