Kryptor FPGA: Open-source hardware end-to-end encryption

Posted on by Emmanuel Odunlade

Data security and privacy are becoming more of a necessary requirement for the Internet of Things (IoT), and other communication-based solutions. This is because for these solutions to become ubiquitous in homes, businesses, and agencies around the world, they have to be immune to data theft or even bad actors who try to cause system damage by introducing false data.

Several firms are developing efforts around hardware security and the team at Skudo is not left behind as they recently announced the development of Kryptor, a professional FPGA development board that is capable of offering all the functionalities of a dedicated Hardware Security Module (HSM) when running their soft-core, within the compact Intel/Altera MAX10 FPGA chip.

Kryptor’s powerful end-to-end encryption eliminates the need for software encryption and also avoids using any Operating System (OS) thereby considerably limiting the options for potential attacks since there’s just one chip to secure.

Designed with versatility and compatibility in mind, Kryptor comes in a small form-factor and can communicate over I2C, SPI or UART. It’s RAM and flash memory circuits are self-contained within the FPGA surface, which provides a much safer architecture compared to the usage of external chips which would require individual security.

While there are other encryption chips which use proprietary, closed-source solutions that limit the flexibility and the ability of users to modify the chip, Krypton, makes use of well-known and proven open-source encryption primitives on a verifiable HSM soft-core, bringing a professional encryption solution to IoT developers and maker communities with an easy plug-and-play module.

Some Specification and features of Kryptor include:

  • FPGA: Intel/Altera MAX10 8K LE (10M08DAF256C8G)
  • Dimensions: 23×35 mm
  • Internal flash: 1376 Kb
  • Internal RAM: 378 Kb total
  • GPIO: 250 available from the FPGA (fewer accessible via the board)
  • Operating frequency: 100 MHz
  • Control: API / encrypted command-line interface (CLI)
  • Platform compatibility: Linux, RPi, Arduino, etc.
  • Duplication protection: Anti-piracy duplication protection via chip ID
  • Encryption speed: symmetric encryption speed up to 108 Mbps on a single core (SPI link speed capped at 2 Mbps)
  • FPGA Features
    • 55 nm TSMC embedded flash (flash + SRAM) process technology
    • 4-input look-up table (LUT) and single register logic element (LE)
    • Flash memory data retention of 20 years at 85 °C
    • Up to 830 Mbps
    • LVDS receiver, 800 Mbps LVDS transmitter

  • HSM Soft-core Encryption Features

    • Key agreement scheme: Elliptic Curve Diffie-Hellman / Curve25519 (ECDH)
    • Symmetric key block cipher: Camellia
    • Asymmetric: ECC25519
    • Cryptographic hash function: Skein
    • True Random Number Generator (TRNG): running in dedicated Hardware (FPGA)
    • Expandable: The FPGA is expandable with external software functions executed inside the chip
    • Optional functions: Other functions (e.g. RSA, AES256, Keccak, etc) can be integrated if needed for legacy applications

While the Kryptor FPGA is targeted at IoT professionals, it is compatible with Arduino and Raspberry Pi, with an Arduino library as well as a free and easy-to-use API for Linux (which can be used on a raspberry pi) already provided to help almost anyone get started with Kryptor in minutes.

The Kryptor FPGA is scheduled to go on sale in March, but information about its price is not yet available. You can, however, follow the project’s progress via its Crowd Supply project page or on the official product page.

Ambient humidity energy harvesters could compete with solar cells

Posted on by mixos

Leveraging the natural adsorption–desorption exchange of water molecules from ambient air at the interface of a nanoporous mesh of protein nanowires, a team of researchers from the University of Massachusetts has demonstrated a durable form of energy harvesting that could potentially compete with solar cells on volumetric power density. By Julien Happich @ eenewseurope.com

Publishing their results in the Nature journal under the title “Power generation from ambient humidity using protein nanowires”, the researchers describe a thin-film device (only 7µm-thick) consisting of a mesh of electrically conductive protein nanowires (sheared from the microorganism Geobacter sulfurreducens) laid on top of a large gold electrode over a glass substrate for the bottom side, and covered with a thin top electrode leaving the mesh exposed to ambient air.

In this configuration, the device, only a few millimetres square, was able to produce a sustained voltage of around 0.5 volts across the two electrodes, delivering a current density of around 17µA/cm2, for over 20h before self-recharging. The authors estimated the device’s power density to roughly 4mW/cm3, two orders of magnitude higher than previous reported energy-harvesting technologies relying on ambient, atmospheric moisture.

They tested their device for more than two months, it maintained a stable direct-current voltage of between 0.4 and 0.6V with fluctuations in voltage only associated with changes in ambient relative humidity (with 40–50% relative humidity yielding the highest voltage. The device was proven to still output power at a relative humidity as low as 20% (comparable to a desert environment) as well as at 100% humidity.

When the film is exposed to ambient humidity, a self-maintained moisture gradient (a depth-dependent difference in moisture adsorption) forms within the film, the researchers observed, which itself creates an ionization gradient in the carboxylic groups or a concentration gradient in mobile protons of the nanowires’ surface functional groups. The resulting charge diffusion induces a counterbalancing electrical field or a potential analogous to the resting membrane potential in biological systems, the authors explain, noting that a wide range of synthetic protein nanowires would likely be suitable for the design of similar ambient air energy-harvesting devices.

Because water molecules in air naturally comprise ionized species, or are ionized when adsorbed on the nanowire surface, they can donate charges to the nanowire, supplying the closed-loop current flow driven by the voltage resulting from the moisture gradient, the researchers further explain.

Arduino based Milliohm Meter with LCD display

Posted on by mixos

One of the best things about being a maker is the ability to make your own tools. We have covered the development of several electronics tools in past, from voltmeters to battery testers. For today’s tutorial, we will add another tool to the list by examining the development of a Miliohm meter made by danielrp @ www.instructables.com

A milliohm meter is a device used in determining the resistance of small resistors, PCB traces, motor coils, inductance coils, and transformer coils, or calculate things like the length of wires. It provides a resolution, not built into regular multimeters, making it easy to get accurate readings in the milliohm range.

There are quite a number of Miliohmeter builds on the internet, but today’s tutorial will chronicle the efforts of instructable user Danielrp. Daniel’s version of the meter is based on a precision current sink and a high-resolution ADC controlled by an Arduino Nano. The current sink is based on the LT3092 precision current source/sink which, using a network of resistors and transistors is set to function as a sink. For the ADC, the high resolution, MCP3422A0 I2C ADC is used.  Just one of the channels of the ADC is used, and it is connected differentially to the Resistor under test “S+ S-“. The MCP3422 is configured as 18bit but as S+ is always going to be greater than S-, the effective resolution is 17bit.

To reduce the influence of the resistance of the test leads on the measurement, the devices use Kelvin connectors as leads to connect the resistor under test to the measurement point.

Sonos acquires the Data-over-sound Pioneer, Chirp

Posted on by Emmanuel Odunlade

The recent moves by Sonos can only be explained as targets towards expanding its connected ecosystem of smart devices and beyond. The wireless speaker company from Santa Barbara California, sometime last year acquired a French company that provides embedded assistants and interfaces for devices that run locally and offline. Of recent, the company set out to add to its league of acquisition the British data-over-sound company, Chirp.io.

Aimed at simplifying device-to-device connectivity via sound, Chirp, which was founded in 2011 at the Computer Science department of University College London, recognized the growing need for seamless low-cost, low power and frictionless communication between devices in the emerging IoT world. They pioneered a data-over-sound technology that creates simple-to-implement solutions to enhance connectivity and identification of machines. The technology helps to improve user experience and bring audio-capable devices into new possibilities thereby substantially lowering the cost for applications like proximity detection, device provisioning, and two-way acoustic NFC. They also capitalized on the digital signal processing capabilities of the Arm Cortex –M7 and Cortex-M4 to provide software-defined acoustic data transmission solutions which are quite robust and reliable, but not resource-intensive.

However, after working together with Sonos for a while now, Chirp has finally confirmed its been acquired by Sonos, describing it as “the perfect match for audio and wireless technology” since Sonos shares the same passion with them.

In an email sent to me, the chirp team mentioned that

“…Chirp has always held firm to a belief that robust, reliable data-over-sound could transform user experiences and bring new possibilities to audio-capable devices. Sonos shares this belief, alongside our common passions for engineering excellence, delightful user experience, and investment in research and development.”

The Chirp team has expressed their pleasure in seeing developers use their SDKs in a number of imaginative applications, but made it clear that starting from March 1ST, the Chirp SDK will no longer be available for users to download.

“…Having joined Sonos, access to the Chirp developer console will be closing on March 1st, meaning users will no longer be able to download Chirp SDK s after that date. If you are using an SDK that you have already downloaded for hobby or proof-of-concept work you can continue to do so freely.”

Meanwhile, these acquisitions will give Sonos a new set of talented employees to quickly bring them into a clear technology differentiation; achieving their goals without having to sacrifice their brand identity. Former CEO of Chirp and new Director of Sonos’ Emerging Technologies already confirmed that efforts with Chirp’s data-over-sound technology will now be focused on Sono’s personal Research and Development program.
