Cryptographic Controller Secures Devices From Edge to Cloud

by Mat Dirjish

Analog Devices’ MAXQ1065 cryptographic controller enlists the company’s proprietary ChipDNA, a physically unclonable functionality (PUF) technology, which boasts the strongest protection for edge-to-cloud Internet of Things (IoT) nodes. According to the company, the security co-processor provides 30x lower power than comparable devices and its extended lifetime and operating range make it viable for long-term deployments in harsh environments. 

The MAXQ1065 offers turnkey cryptographic functions for root-of-trust, mutual authentication, data confidentiality and integrity, secure boot, secure firmware update, and secure communications. It includes standard algorithms for key exchange and bulk encryption or complete transport layer security (TLS) support.

Additionally, the device integrates 8 kB of secure storage for user data, keys, certificates, and counters with user-defined access control and life-cycle management. Other features include a TLS/DTLS 1.2 command set built upon hardware-based ECDSA, ECDHE and AES for authentication, key exchange and secure communication, and an operating power of 100 nA during power down mode.

The MAXQ1065 comes in a 12-pin TDFN package measuring 3 mm x 3 mm x 0.75 mm. Pricing is $0.83 each/1,000. An evaluation kit, the MAXQ1065EVKIT, is available for $90.10.

Getting excited about and moist under the collar over this hot device but yearn and burn for deeper details and data? If so, cool off and yearn no more by perusing the MAXQ1065 datasheet. Also take a look at the MAXQ1065 intro video.
