A New Inter-Domain Information Sharing Smart System Based on ABSES in SDN.

With the continuous innovation and development of agent technology, the application of smart technique is gradually changing to intelligent and human-centered technology. Also, intelligent technique is involved in many fields, and software defined network (SDN) is one of them. SDN is one of the most popular and most promising new technologies in the current network area, which has particular advantages over other traditional networks. However, most of the research work focus on the efficiency and function of SDN, while the access control and ciphertext search function in SDN have not been taken into full consideration. In this paper, we propose a new smart system based on SDN. It also equips with the functions of fine-grained access control and searchable encryption function, which combines a novel attribute-based searchable encryption scheme (ABSES) with SDN architecture. Our construction realizes inter-domain information sharing, fine-grained access control, and ciphertext searchable function. The proposed ABSES effectively ensures the security of ciphertext stored in data center, and that users cannot obtain unauthorized information or illegal network resources without any certification. It reduces network bandwidth and local resources, while improving the scalability and flexibility of SDN access control at the meantime. Finally, our ABSES is proved to be correct and secure under chosen-keyword attack. The comparison with other representative attribute-based searchable encryption schemes demonstrates that our ABSES has somewhat better performance. The proposed new smart system can be used in human life and add more convenience to our daily life.
