DS28E50Q+U

DS28E50Q+U is a DeepCover secure SHA-3 authenticator with ChipDNA PUF protection. This secure authenticator combines FIPS202- compliant secure hash algorithm (SHA-3) challenge and response authentication with Maxim’s patented ChipDNA™ technology, a physically unclonable function (PUF) to provide a cost-effective solution with the ultimate protection against security attacks. The ChipDNA implementation 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. It is used in applications such as authentication of medical sensors and tools, secure management of limited-use consumables, IoT node authentication, peripheral authentication, reference design license management, printer cartridge identification, and authentication.
