“…We pay attention to the schemes [ 30 , 31 , 32 , 33 ] having the similar features as our proposed scheme, i.e., use of hybrid encryption, no need of trusted third party, and effective use of in-network caching mechanism. We compare our scheme with the schemes with respect to the various factors associated with the encryption-based access control in NDN, as described in Table 4 .…”

“…Although, the scheme [ 31 ], provides the cache awareness in the same level as our work, it incurs higher storage and computational burden in the network since it needs to store the key management tables at the edge router. When an interest request arrives, it needs to check against both tables for further message flows and key management operations.…”

“…Furthermore, the computational time for the router is smaller than the content producer since the router only needs to forward and reply the packets without any computation. Thus, the consumer and the router in our scheme are free from high computational overhead compared to [ 31 , 32 , 33 ] and similar to [ 30 ], as shown in Table 4 .…”

“…Although all other schemes [ 30 , 31 , 32 , 33 ] fulfill the usage of in-network caching in parallel, our scheme provides content retrieval time reduction with 10% to 25% for cached content since the encrypted content is available for all consumers from the router’s cache and only key re-encryption is required at the edge router. To sum up, ES_CD provides comparable properties for content confidentiality with others schemes and guarantees effective cache utilization for every content.…”

“…Even NDN packets do not contain any information about the source host where they were originally sent; contents security and privacy are still needed. Different cryptographic approaches have been explored in access control solutions for NDN, such as attribute-based encryption, broadcast encryption [ 32 , 33 ], role-based encryption, identity-based encryption [ 30 , 34 ], proxy re-encryption [ 31 , 35 , 36 ], and so on [ 7 , 37 , 38 ]. These approaches are examined below.…”

NDN is one of the new emerging future internet architectures which brings up new solutions over today’s internet architecture, facilitating content distribution, in-network caching, mobility support, and multicast forwarding. NDNs ubiquitous in-network caching allows consumers to access data directly from the intermediate router’s cache. However, it opens content privacy problems since data packets replicated in the router are always accessible by every consumer. Sensitive contents in the routers should be protected and accessed only by authorized consumers. Although the content protection problem can be solved by applying an encryption-based access control policy, it still needs an efficient content distribution scheme with lower computational overhead and content retrieval time. We propose an efficient and secure content distribution (ES_CD), by combining symmetric encryption and identity-based proxy re-encryption. The analysis shows that our proposed scheme achieves content retrieval time reduction up to 20% for the cached contents in our network simulation environment and a slight computational overhead of less than 19 ms at the content producer and 9 ms at the consumer for 2 KB content. ES_CD provides content confidentiality and ensures only legitimate consumers can access the contents during a predefined time without requiring a trusted third party and keeping the content producer always online.
