Secure and Optimal Content-centric Networking Caching Design

Due to accretion demand and size of the contents makes today's Internet architecture inefficient. This host centric model does not seem effective to cater current communication needs where users focus on desired content. As a result, translation between content information and networking domain should take place, typically consisting of an establishment of a delivery path between the content provider and the content consumer. This translation is generally an inefficient constraint, as data location and data popularity are neglected, which leads to over consumption of network resources. The increasing demands of highly scalable and efficient distribution of contents have motivated the development of future Internet architecture based on named data objects. Currently, Content Centric Networking (CCN) is gaining attention as the future Internet architecture where contents themselves are the primary focus, rather than the location of the content. This paper provides an insight into efficient caching management policies used currently for large file caching, our proposed approach along with its justification and validation behind the idea for designing the best caching strategy in CCN. However, caching policies can be misused if attackers use cache as storage to make their own content available for attacks or privacy leaks. We conclude with the need for security mechanisms for protecting the cache and the security measures to prevent any misuse of it.
