摘要：As one of the most important uses of the Internet of things (IOT), the intelligent household is becoming more and more popular. There are many fragile nodes in the intelligent household and they are bound to encounter some potential risks of hostile attacks, such as eavesdropping, denial of service, error instructs, non-authorized access or fabrication and others. This paper presents a method of design and implement of secure nodes for the intelligent household based on the IOT technology, besides giving the hardware model of nodes, the management of key, the access authentication of network, the transmission of encrypted data, and the alarm based on intrusion detection and other security mechanisms. That is, to improve the security of the based-IOT intelligent household from the viewpoint of nodes security. A test platform is built and the results of simulation prove that the proposed method can effectively improve the security of the intelligent household from access safety and transmission security.

摘要：针对传统智能锁安全隐患频发、用户体验欠佳、售价昂贵等问题,提出一种基于Android things的智能门禁系统设计方案。该方案采用Android things作为开发环境,检测到预设的语音命令则开始进行初次身份认证;进一步进行视频图像采集,本地根据身份认证结果,结合语音命令所代表的具体内容,完成类似开门等行为动作。方案将本地数据上传到云端,利用云服务提供的计算资源,减轻本地计算负载,同时提供更多智能互联及扩展功能。

摘要：物联网技术爆炸式发展,从可穿戴设备到车辆互联,再到智慧城市等方面,正在改变人们的日常生活。过去,人们习惯将雾计算看作云计算的延伸;事实上,雾计算逐渐成为传输、处理分布式大数据的理想解决办法。提出一种考虑拜占庭容错的组网方法,以及两种针对物联网雾计算的资源分配算法。目的是设计一个称作"SIoTFog"的安全雾计算网络,能够抵御拜占庭错误影响并提高传输、处理物联网大数据的效率。考虑两种情况,即面对单一拜占庭错误和多拜占庭错误的不同隐患时,比较算法性能。选择时延、传输时总转发跳数和设备利用率作为性能指标。仿真结果表明,该方法可助力实现高效、可靠的雾计算网络。

摘要：＂真实并非绝对。真实的事情是高压的专制系统的体现,这种高压政治维持了它们是真实性。＂在对战后秩序的妄想中,赤瀨川原平的＂资本主义现实主义论＂不无道理：但对很多人来说,电视、咖啡桌、广告……以至于围绕着他们的整个世界,看起来都更像一个近乎相悖的建构。赤瀨川的现实主义标签是刚刚被贴上的,由于他进行的艺术实践正在塑造而不是代表着世界。

摘要：Encryption can make up for a litany of security snafus--from a bad firewall to an unrelenting hacker to a lost *** data is encrypted, criminals can’t use or sell ***,if encrypted data goes missing,companies are protected from disclosure requirements in most states.

摘要：在移动互联网的时代,许多家庭中的电视已经被束之高阁。然而,挪威人却用他们的创意让电视焕发了新的生命力。在挪威,＂直播＂的概念不只适用于综艺节目和体育比赛,他们还直播火车旅行,直播邮轮航海,甚至直播木柴燃烧,直播织毛衣……这些单调而漫长的节目看似无聊,却因为营造出一种身临其境的感觉而吸引了大批观众。当忙乱的生活越来越使人感觉疲惫,＂慢电视＂悄然兴起,刮起了一股悠闲的风。

摘要：With the rapid development of the embedded technology, research and implement of the Internet of things will be a new technology revolution, yet the implement of the Internet of things is on the base of the communication between the things. For this reason, realizing the function of communication between singlechip is particularly important. Based on the characteristics of the embedded microcontroller, we analyzed the traditional PC TCP/IP protocol, and appropriately tailored TCP/IP protocol cluster on the basis of the characteristics of embedded singlechip. At last, we realized the reduced TCP/IP protocol cluster suitable for embedded singlechip, on AVR singlechip platform.

摘要：针对中国老龄化人口现象,以及对21世纪新一代知识型、技术型老年人的生活质量的关注,借助于物联网技术针对老人的生活状态、老人的看护监管和老人使用的产品设施,以及老年人所面对的一系列问题,提出改变老年人生活的全新模式。
