SecureRF and its CEO Louis Parks were recently profiled by Stacey Higginbotham in the weekly IoT-based Stacey Knows Things newsletter and at Parks described some of the challenges associated with securing the IoT, and he talked to Higginbotham about SecureRF’s cryptography solutions for low-resource devices, such as 8- and 16-bit microcontrollers. “As both security and IoT continue to gain attention, SecureRF has technology worth looking at,” […]

Imminent Arrival of Quantum Computers Spells Danger for Private Data

Published April 27, 2017 by SecureRF in Cryptography, Quantum Computers

In a blog post we published last November, we reported that quantum computers might be available in the next ten to fifteen years. However, with companies including Google and IBM significantly ramping up their efforts to make quantum computing a reality, it is likely that commercial availability for these “super computers” will arrive ahead of schedule. A recent article in Wired magazine noted that Google […]

Sensor Security in Manufacturing and Construction IoT Applications

Published March 30, 2017 by SecureRF in Cryptography, IoT Security

Manufacturing and construction depend on large networks of sensors, actuators and controllers to operate, control and monitor systems and processes. Much of the equipment used in these industries comes with built-in devices for sensing, data collection and communicating. The data flowing through these devices helps both industries meet a number of requirements including efficiency, safety, quality and productivity. A successful attack can compromise any or […]

Webinar Replay Available: Quantum-resistant Cryptography for the IoT

Published January 31, 2017 by SecureRF in Cryptography, News & Events, Webinar

Customer concerns related to IoT security are becoming more prevalent as IoT moves into the mainstream. However, many companies involved in the production of low-resource IoT devices driven by 32-, 16- and even 8-bit processors are not able to implement contemporary security solutions with acceptable runtime and resource allocation. This on-demand webinar is a special opportunity to hear one of our founders, Dr. Iris Anshel, explain […]

Basics of Cryptography for Chip Design Engineers

Published December 27, 2016 by SecureRF in Cryptography

The purpose of cryptography is to assure data protection, authentication, and non-repudiation (so no one can deny they took part in a communication). While codes and encryption have existed in one form or another since ancient times, it’s thanks to advances in electronic cryptographic systems since the 1970s that today we enjoy things like secure e-commerce transactions and mobile communications. When two people – or […]

SecureRF CTO Presents WalnutDSA Asymmetric Signature Scheme at NIST Lightweight Cryptography Workshop 2016

Published December 13, 2016 by SecureRF in Cryptography, Internet of Things, IoT Security

In a presentation at the NIST Lightweight Cryptographic Workshop 2016, Derek Atkins, SecureRF’s Chief Technology Officer, introduced the audience to WalnutDSA, our lightweight, public-key signature scheme for use in low-resource IoT devices. WalnutDSA’s major benefits, Atkins explained, include its quantum resistance and its rapid signature verification, especially in comparison with ECDSA. Atkins took the audience through the mathematical foundations of WalnutDSA, which includes E-multiplication, our […]

Lightweight Cryptography for Embedded Systems in the IoT

Published November 29, 2016 by SecureRF in Cryptography, Embedded Systems, Internet of Things

Until a few years ago, the security of embedded systems was seldom a priority for vendors or consumers. Embedded systems were typically not attached to public networks, and tampering with them was arduous and required specialized software skills. The threat level against them was low to non-existent. But now that embedded systems and processors are key components in the Internet of Things, the threat level […]

Quantum Computing’s Threat to Current Cryptosystems

Published November 10, 2016 by SecureRF in Cryptography

The computers and communication systems we use today rely on cryptographic systems commonly based on factoring large numbers or finding discrete logarithms. Both these methods are secure because conventional computers lack the sheer computational power needed to break them. For example, a recent factoring for RSA with a long key was RSA-220 (220 decimal digits, or 729 bits), which took an estimated 370 CPU years.  […]
