Embedded systems continue to be targeted by increasingly sophisticated hackers. Designers are seeking to protect product integrity against aftermarket counterfeits and are strengthening assurances that the sensors within these devices are genuine clones and not inferior. The DS28E50 provides embedded system developers with an advanced capability to prevent counterfeiting, aftermarket cloning, and unauthorized use of connected smart, industrial, medical, and consumer devices.
In addition to providing the industry's first SHA3-256 authentication IC, the DS28E50 also integrates Maxim's ChipDNA™ Physically Unclonable Function (PUF) technology to prevent IC-level attacks routinely attempted on security ICs. Using ChipDNA technology, which is derived from the naturally occurring random analog features of fundamental MOSFET devices, the secret keys that protect all data stored on the DS28E50 are generated only when needed and are never stored on the chip.
Key advantages of the DS28E50:
Cost-effective Crypto-Strong Security: The FIPS 202-compliant SHA3-256 implementation provides a cost-effective and less complex way to implement highly advanced and secure challenge/response authentication to defend against spoofing and monitor or restrict peripheral usage. ChipDNA PUF technology strongly protects all sensitive data stored on the device from security attacks.
Ease of implementation: Single-contact 1-Wire® communication simplifies the interface for application completion. The IC includes secure EEPROM for end-user application data with multiple configurable and irreversible memory protection modes. No device-level firmware development is required (host-side microcontroller firmware is needed). Additionally, a factory programming service is available for simplified secure key management.
Compact, low-power, and robust package: the IC requires only 3.3V, operates between -40°C and +85°C, includes ±8kV HBD (Human-Body) model electrostatic discharge (ESD) protection, and is housed in a 6-pin, 3mm × 3mm TDFN package.
