ChaoLogix: Integrated Security
By Ernest Worthman - 13 Apr, 2015 - Comments: 1

Semiconductor Engineering sat down with ChaoLogix’s chairman and CEO, Brian Kelly, and Chowdary Yanamadala, senior vice president of business development, to talk about the company's approach to securing semiconductors from side-channel attacks. SE: Given that the term “data security” has almost as many definition as there are braches, let start with a basic question: What does data s... » read more

Drill Down: Embedded NVM Technology
By Ernest Worthman - 02 Apr, 2015 - Comments: 0

Many of the next-generation devices that will be seen on the IoT/E will have power, footprint, and electronic constraints as never before. Electronic flash memories (eFLASH), and their derivatives are seen as a realistic solution to many of these design constraints for small form factor and simple IoE devices. “NVM will be very important for the IoE from the perspective of saving power," ... » read more

Wireless Technologies For The IoE
By Ernest Worthman - 02 Apr, 2015 - Comments: 0

It's generally understood the [getkc id="76" kc_name="Internet of Everything"] eventually will be the interconnect platform of all things, wireless and wireline. The utopian scenario is to have a common platform, with standardized protocols, which everyone builds to. Will that happen? Perhaps, but for a time, especially while the IoE evolves, that won’t be the case. Count on the early IoE bei... » read more

IPsec Security In IPv6
By Ernest Worthman - 02 Apr, 2015 - Comments: 0

IPv6 is starting to show up in around the Internet. Adoption is slow, but with the magic number of 4 billion- plus IPv4 addresses about to be reached, IPv6 will see a much faster pace of adoption as the IoE gains momentum. There is a lot of excitement about all the enhancements within IPv6. Some even claim it is the answer to Internet security. But so far it has not lived up to that promise.... » read more

A New Infrastructure For The IoE
By Ernest Worthman - 09 Mar, 2015 - Comments: 0

The IoE is going to change, radically, a number of paradigms. Top among them is exactly how we are going to route the yottabytes of data that will flow between objects of the IoE, which is made more difficult because 70% of that data will not be on the traditional wireless or wired pipeline. To date, lots of attention has been paid to bringing intelligent objects on line to connect everythin... » read more

Where The IoT Money Will Be
By Ernest Worthman - 05 Mar, 2015 - Comments: 0

As we get closer and closer to figuring out what the Internet of Things—or increasingly, the Internet of Everything (IoE)—will and won’t be, one of the themes that shows up regularly is exactly how to monetize it. “A large portion of marketing dollars are wasted when the wrong offers are made to the wrong people at the wrong place and time,” notes Jon Gettinger Sr. vice president o... » read more

Physically Unclonable Functions
By Ernest Worthman - 05 Mar, 2015 - Comments: 0

Physically unclonable functions (PUFs) are emerging as a novel way to protect a variety of ICs. In today’s world of cyber threats, vulnerabilities, insecure networks and hardware, and intrusions, it is finding a renewed interest. The technology on which it is based has been around since the mid-1990s in its present form and the term PUF was cloned in the early 2000s. PUFs find their anc... » read more

One-on-One: Steven Woo
By Ernest Worthman - 05 Mar, 2015 - Comments: 1

Semiconductor Engineering sat down with Steven Woo, vice president and distinguished inventor at [getentity id="22671" e_name="Rambus"], to talk about the IoT and where the real problems are showing up. SE: What are the big challenges as we move toward an [getkc id="76" comment="Internet of Things"]-connected world? Woo: The challenges we see, moving forward aren’t particularly related... » read more

Challenges For IC Security
By Ernest Worthman - 05 Feb, 2015 - Comments: 0

Keeping chips secure is really a foot race between the good guys and the bad guys. Going forward, expect heavily funded, grouped efforts to place tremendous pressure on security envelopes. This includes everything from simple home devices, such as routers, to the most critical infrastructures, such as power, telecom, transportation, and soon, the IoT.

BLE For The IoT
By Ernest Worthman - 05 Feb, 2015 - Comments: 0

Bluetooth low-energy (BLE) is one of the emerging disruptive technologies for the IoT. Also referred to as Bluetooth low-power and Bluetooth smart, as the Bluetooth SIG is calling it, this technology will enable the next level of IoT vertical devices, such as medical devices, home automation, retail, wearables, and much more. For consumers, it comes down to the Internet of Your Things (Io... » read more
