Authenticator IC features SHA3-256 cryptographic engine

SHA3-256 authentication allows the DS28E50 to provide challenge-and-response authentication, and a strong defence against counterfeiting, unauthorized usage and other application problems.

In addition to being the industry’s first SHA3-256 authentication IC, the DS28E50 also integrates Maxim’s ChipDNA physically unclonable function (PUF) technology to prevent the IC-level attacks that are routinely attempted on security ICs. ChipDNA technology is derived from the naturally occurring random analog characteristics of fundamental MOSFET devices. Secret keys that protect all DS28E50 stored data are generated when needed and are not stored on the chip.
