Analog Devices, Inc. has released a cost-effective solution to detect and help prevent product counterfeiting or misuse. DS28E30 1-Wire ECDSA Secure Authenticator. Combining an industry standard FIPS 186 ECDSA-based fixed-function cryptographic toolbox, secure storage of keys and application data, and a single-point 1-wire interface, the device can be easily integrated into existing or new designs with minimal complexity minimum.
The device provides security features including a monotonic, non-resettable, decrement only counter and a 1Kbit universal EEPROM that can optionally be protected by ECDSA to store application data and end product life cycle information. It also allows management of tools, sensors, and other peripherals with limited life.
It is offered in a small 1.2mm x 1.4mm four-ball WLP with a 0.5mm pitch. And each component is programmed with ADI public key certificate before delivery to ensure authenticity. It offers a wide operating range, 1.62V-5.25V, -40 ° C to +85 ° C.
