This provides protection for IoT, medical and wearable devices, against invasive security attacks. The security co-processor provides 30x lower power when compared to similar products and its extended lifetime and operating range make it suitable for long-term deployments in harsh environments, ADI said.

The MAXQ1065 security co-processor provides 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. The device integrates 8Kbytes of secure storage for user data, keys, certificates and counters with user-defined access control and life cycle management functionality for IoT equipment.

The MAXQ1065 includes a TLS/DTLS 1.2 command set built upon hardware-based ECDSA, ECDHE and AES for authentication, key exchange and secure communication. Additional countermeasures against security attacks include the irreversible ChipDNA PUF technology which is used to cryptographically protect all stored data from discovery. The MAXQ1065 operates at 100nA during power down mode.

The MAXQ1065 is available as of now for $0.83 (price each per 1,000 units) in a 12-pin 3mm by 3mm by 0.75mm TDFN package. The evaluation kit is available for $90.10.
