Security and privacy issues of physical objects in the IoT:Challenges and opportunities

In the Internet of Things(IoT),security and privacy issues of physical objects are crucial to the related applications.In order to clarify the complicated security and privacy issues,the life cycle of a physical object is divided into three stages of pre-working,in-working,and post-working.On this basis,a physical object-based security architecture for the IoT is put forward.According to the security architecture,security and privacy requirements and related protecting technologies for physical objects in different working stages are analyzed in detail.Considering the development of IoT technologies,potential security and privacy challenges that IoT objects may face in the pervasive computing environment are summarized.At the same time,possible directions for dealing with these challenges are also pointed out.

A growing social networks model of physical objects in IoT

In Internet of Things （IoT） cial networks of physical objects , physical objects can build their own social networks. How do so- generate, and what characteristics do the social networks have. In order to solve these problems, according to the interaction of physical objects in IoT, this paper presents a growing social network model of physical objects and researches the attachment mecha- nism of the model that includes three modes, physical distance, social distance and preference. Through the simulation realizations of the model, the characteristics （e. g. degree distribution, com- munity structure） of social network are analyzed. The model can forecast the growth of social networks of physical object in IoT and simulate social networks of physical objects in the large scale IoT.

The Impact of Internet of Things in Manufacturing Management

The study investigated the impact of the Internet of Things in manufacturing management. Specifically, the study examined how IoT implementation and management affect organizational efficiency in Camanov Ltd.;and to what extent IoT implementation contributes to the saving of cost and time of the organization. The research design is a survey. The population of this study consisted of all 141 staff of Camanov Ltd. Port Harcourt. Since the population is not large, the researcher conducted a census of all, and 126 staff completed a structured questionnaire. The two research questions were analyzed using simple percentages and all two hypotheses were tested using sample proportion statistics (Z test) at a 0.05 level of significance. The result showed that the Internet of Things has a significant impact on organizational efficiency in Camanov Ltd. (Z = 4.73);and that the Internet of Things significantly contributes toward saving cost and time of the organization Camanov Ltd (Z = 4.95). It was recommended that organizations should encourage training of personnel in the improved limitless possibility of information gathered from the Internet of Things framework which supports planning, budgeting and monitoring approaches, providing more reliable information to support actions, in particular in the decision-making process, to enhance productivity.

面向人机物融合的数联网标识解析技术

以数据的深度挖掘与融合应用为主要特征的信息化3.0阶段正在开启,传统静态环境下的软件正向人机物融合环境下开放动态的复杂软件演化.如何在不可信不可控的互联网之上实现全网一体化可信可管可控的数据互联互通是当前亟待解决的难题,以数字对象架构、标识解析技术为代表的数联网技术体系为上述挑战提供了一种可行思路.针对互联网上数据资源共享交换过程中广泛存在的传输效率低、协调成本高、安全管控难等问题,提出面向人机物融合的数联网标识解析技术规范,并基于人机物融合环境中各实体之间数据资源可发现、可获取、可理解、可信任、可互操作等需求,设计实现面向人机物融合的数联网数字对象标识解析协议以及数字对象标识系统.最后,对所实现的数字对象标识系统进行系统测试与评估,并在实际应用场景中对其有效性进行验证.

论Internet与Internet of Things

从Internet发展历史及应用环境变化的角度讨论IoT(Internet of Things)提出背景、内涵、组成结构和体系结构等关键问题。在分析对IoT的典型定义的基础上,笔者认为"ITU把IoT作为Internet平台在应用领域实现人、机、和智能化物理对象(SPO)信息全方位互通和实践普适计算理念的下一代Internet及其应用系统的概括"是对IoT更为合理的广义定义。以该定义为基础,全面地分析了"由多个用户域网(CPN)通过骨干通信子网互联"的基本组成结构,讨论了两类SPO-CPN的基本组成结构及其支撑技术;指出SPO的引入主要影响CPN资源网络中的接入部分,属于应用系统的范畴,对Internet基本技术影响甚微。笔者不赞同以欧盟为代表的把IoT定义为联物专用网的狭义定义,指出其IoT模型和体系结构研究混淆了网络平台与应用系统,实质上是网络应用系统模型和体系结构。

物联网统一编码体系的研究

针对目前物联网编码标志存在的编码体系不统一、方案不兼容、局限于某些领域、无法实现跨行业、跨平台、规模化的物联网应用等一系列问题,提出了一种新的编码思想和体系。它抽象出一种提供位移的载体物品和一般的实体物品,而现实中的产物品可以看做是由两者以不同方式的结合,对实体物品和载体物品采用统一编码,就完成了对物品在生产和流通阶段的编码标志。基于云计算的解析服务系统对物品的所有者和状态的信息进行动态更新,就能满足物联网对物品的实时监控和智能化管理。
