根据Venture Development (VDC)最新的一项研究，在未来的几年内，物联网(Internet of things)将颠覆嵌入式系统开发厂商现有的业务模式，并将进一步推动采用更安全的新技术。
VDC在日前于《DESIGN West》的一场小组讨论上发布其研究报告指出，当今正开发的嵌入式计划中，半数都利用了机器对机器(M2M)连接，预计在未来三年内还将增加到69%。VDC副总裁Chris Rommel表示，随着更多嵌入式系统连接到网路与智能手机，“75%以上的OEM认为，目前的业务模式将因为物联网的影响，而在未来三年内逐渐转型。”

物联网推动采用安全新技术
安全性是最令人担心的问题。超过70%的受访OEM表示已经感受到安全漏洞了，而针对这样的问题，他们较喜欢使用更多的加密技术与认证。

IoT/M2M对业务模式的影响和重要性
ARM业务开发经理Ian Ferguson指出，物联网应用将分三个阶段出现。首先他们最初将仅限于内部封闭的系统中，接着将会开放至消费用户，最后则将在各种装置与服务供应商之间建立起互通作业性。
Ferguson表示，无线厂商“正在寻找如何将装置连接到新服务的方式，因此Sprint和DoCoMo将会是你的新客户，他们可能会找到能更快实现这一点的方法。”他并提醒工程师们，预期医疗与健身设备将是发展初期的市场。"
瑞萨电子行销副总裁Peter Carbone表示，芯片业已经实现了这种转型了。他将2013年称为40nm微控制器元件。
“1Mb将是最小的快闪记忆体模组，而带四核心的处理器将轻易达到200MHz，”Carbone说，“现正开发中的28nm MCU至少将包含2至4Mb快闪存储器，而多核心也将成为公认标准。”
他补充说，芯片供应商并已在MCU模组中嵌入加密、身份验证以及和安全密钥维护等功能。
分析软体则是下一个关键部份，Motomic Software公司副总裁Roger Edgar表示。Motomic Software公司致力于为IoT系统开发专用式码。
“你可能更清楚浏览你公司网站的访客，却未好好了解在你M2M 系统中的客户，”Edgar说，“你手中握有一大堆资料却未能善加利用。”

The Internet of things will shake up business models for embedded systems developers over the next few years, according to a new study by Venture Development Corp. It will also and drive the adoption of more security technologies, said an analyst in a panel discussion at DESIGN West here.
Half the embedded projects in the works today are making some use machine-to-machine links, rising to 69 percent in three years, the study said. As embedded systems link to the Web and smartphones, “more than 75 percent of OEMs say their business models will shift over three years because of Internet of things,” said Chris Rommel, a vice president at VDC (Natick, Mass.) presenting the results in a panel discussion.
Security is the biggest bugaboo. More than 70 percent of OEMs surveyed said they are already feeling security vulnerabilities. More use of encryption and authentication are their preferred techniques for dealing with the issue, he reported.
IoT apps will emerge in three phases, predicted Ian Ferguson, a business development manager for ARM on the panel. Initially they will be confined to internal closed systems that are later opened up to consumers and finally to interoperable mixes of device and service providers.
Wireless carriers will be rainmakers, Ferguson said. “They are looking for ways to connect devices to new services—so Sprint and DoCoMo will be your new customers and they might find ways to make this happen quicker,” he told engineers, predicting health and fitness devices will be an early market.
Chips already are enabling the shift, said Peter Carbone, vice president of marketing at Renesas. He dubbed 2013 the year of the 40nm microcontroller.
“A megabyte will be the smallest flash block you put down and the processors will easily hit 200 MHz with up to four cores,” Carbone said. “The 28-nm MCUs now in development will pack two to four Mbytes flash minimum and multicore will be standard."
Chip vendors are already embedding in the MCUs blocks for encryption, authentication and secure key maintenance, he added.
Analytics software is the next key ingredient, said Roger Edgar, a vice president of Motomic Software that develops the code specifically for IoT systems.
“You know more about the casual visitor on your Web site than the customer on your M2M system, said Edgar. “You have a boatload of data you are not taking advantage of,” he said.
