Abstract

Next generation network is a hot topic that lots of researchers have paid their attention to this point. The main idea is making people more comfortable and convenient. This paper presents a novel wisdom network which tends to achieve the above mentioned advantages. This network is composed by User Part and Server Part. Further, Server Part is divided into Gateway Server part and Data Server part. According to the network architecture, some design principles are analyzed and modeled, including the following aspects: resource registration and retrieval, data pieces replication, Gateway Server performance and load balance achievement. Key word:Wisdom network, resource registration and retrieval, data replication, load balance. DOI: http://dx.doi.org/10.11591/telkomnika.v11i11.3584

Abstract

In space networks, the long time delay, large scale and maintainability of difficultly nature makes key management more difficult than ground wireless networks. The main challenge is how to handle 1-affects-n problem that become more serious as entities spread over a wide geographic area. To solve it, this paper proposes a one-to-many mapping shared key agreement, which is based on one-to-many encryption mechanism model. In the proposed key agreement, each entity has different decryption key and shares an encryption key. When an entity joins or leaves network, updated keys only are public encryption key and its decryption key. However, the other entities’ secret key remains unchanged, so as to each member has the ability to update key autonomously. Consequently the performance of the proposed key management scheme is unrelated to the network scale, node mobility and topology structure. It is shown that our proposed key management scheme not only improves the efficiency and flexibility for space networks, but also achieves good security properties, including forward security and backward security and many more by theoretical analyses. DOI: http://dx.doi.org/10.11591/telkomnika.v11i2.2029
