Analog Devices has released the ultra-low-power MAXQ1065 cryptographic controller featuring its proprietary ChipDNA physically unclonable functionality (PUF) technology, which provides the strongest protection for edge-to-cloud IoT nodes, including medical and wearable devices, against invasive security attacks. The security co-processor offers 30-times lower power compared to similar products and its extended lifetime and operating range make it ideal for long-term deployments in harsh environments.
The device security co-processor offers turnkey cryptographic functions for root-of-trust, mutual authentication, data confidentiality and integrity, secure firmware update, secure boot, and secure communications. It incorporates standard algorithms for key exchange and bulk encryption, or complete TLS support. The device combines 8KB of secure storage for user data, keys, certificates and counters with user-defined access control and life cycle management functionality for IoT equipment.
“With billions of deployed devices and ongoing exponential growth, it’s common knowledge that IoT devices are a favourite hacking target, normally with malicious intent. The threats to the systems critical to society such as infrastructure, medical and industrial are very real and without proper protection they may be compromised,” said Scott Jones, managing director, Micros, Security and Software Business Unit at Maxim Integrated, now part of Analog Devices. “The MAXQ1065 with ChipDNA technology is designed to address these threats. Built with the most advanced security technology and targeting IoT applications, it provides a superior level of protection for your equipment and has the technology to future-proof designs against tomorrow’s system threats.”
The device's low power consumption and wide operating range make it ideal for battery-powered applications, and the extremely small footprint and low pin count facilitate easy integration into medical and wearable devices. Its life cycle management provides flexible access control rules throughout the major life cycle stages of the device and end equipment, assuring long-term operation in harsh environments. The device combines its proprietary ChipDNA PUF technology, which guards against invasive attacks since any attempt to probe the PUF cryptographic destroys its value. The device is also supported by the company’s secure key preprogramming service for customers who require keys, data and life cycle state initialised before shipment to a contract manufacturer.
