Communication and Security Integrated Space-Earth Heterogeneous Network Architecture by Xiaoning ZHANG, Lidong ZHU

“…To achieve the integration of space information networks and high-speed rail, ship and civil aviation private communication networks, this article proposes to leverage the mechanism of identifi er and locator separation to construct the communication and security integrated space-earth heterogeneous network architecture.The proposed network architecture included four network layers (i.e., space-earth heterogeneous network service layer, space-earth heterogeneous network traffi c layer, space-earth heterogeneous network routing layer and space-earth heterogeneous network access layer) and fi ve network identifi ers (i.e., service identifi er, traffi c identifi er, routing identifi er, access identifi er and host identifi er).With the method of effi cient network identifi er mapping, the communication and security integrated requirement for space information networks and ground private communication networks could be guaranteed.…”

Digital steganography model and its formal description by Haitao SONG, Guangming TANG, Yifeng SUN, Yang WANG

“…In order to make the research of digital steganography model develop synchronously with steganography research,three digital steganography models from general to specific are proposed,and each model was formalized.Through study on digital model,the essential principles of steganography algorithm were summarized to guide the further development of steganography.Firstly,aiming at the problem that the existing model cannot describe the emerging steganography algorithms,a general digital steganography model was proposed to describe nearly all steganography algorithms.Secondly,in view of the important position of the cover modification steganography algorithm in the research of steganography,a cover-modification digital steganography model was proposed.Then,for the current mainstream image adaptive steganography algorithm,a digital image adaptive steganography model with minimal distortion was proposed.Four typical steganography algorithm were selected as examples which were described by the proposed steganography model to validate the effectiveness of the proposed model.…”

Discussions about application of blockchain in IoT systems by Zhen GAO, Qimei CUI, Xuefei ZHANG, Xiaofei WANG

“…Blockchain technology has attracted wide attention in recent years,and many industries are trying to solve the reliability and security problems of traditional centralized schemes in information systems based on blockchain technology.However,the connection between the blockchain network and industry entities must rely on the Internet of things (IoT) technology.Therefore,combining the blockchain and IoT technology to solve the pain points of vertical industries is the current research hotspot.On the other hand,the development of IoT itself is also limited by the centralized architecture,and how to use the blockchain technology to solve the predicament of IoT is also an important issue.Although there are many blockchain related applications,some of them are actually not suitable for blockchain technology.Firstly,the proper logic of blockchain applications was discussed.Then suitable application scenarios of blockchain technology were introduced by typical case analysis.Finally,four common problems when combining blockchain and IoT were discussed.…”
