Analog Devices / Maxim Integrated DS28E38 DeepCover® Secure ECDSA Authenticator
Analog Devices DS28E38 DeepCover® Secure ECDSA Authenticator is an ECDSA public key-based secure authenticator that incorporates Analog Devices' patented ChipDNA™ PUF technology. ChipDNA technology involves a physically unclonable function (PUF) that enables the DS28E38 to deliver cost-effective protection against invasive physical attacks. The DS28E38 uses the random variation of semiconductor device characteristics that naturally occur during wafer fabrication. The ChipDNA circuit generates a unique output value that is repeatable over time, temperature, and operating voltage.
