DS28E50 DeepCover® Secure SHA-3 Authenticator

Analog Devices DS28E50 DeepCover® Secure SHA-3 Authenticator provides a cost-effective solution with ultimate protection against security attacks. This authenticator combines FIPS202-compliant secure hash algorithm (SHA-3) challenge and response authentication with Analog Devices patented ChipDNA™ technology, a Physically Unclonable Function (PUF). The DS28E50 authenticator provides ChipDNA implementation that utilizes 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. Attempts to probe or observe ChipDNA operation modify the underlying circuit characteristics, thus preventing the discovery of the unique value used by the chip's cryptographic functions.
