The DS28E50 DeepCover secure hash algorithm 3 (SHA3-256) authenticator IC is designed to cost-effectively deliver the latest technology for challenge-and-response authentication. It provides the strongest defense against counterfeiting, unauthorized usage, and other application problems in a secure IC solution suited for teams with limited or no cryptography expertise, the company says.
The DS28E50, says the company, provides embedded system developers with advanced ability to prevent counterfeiting, aftermarket cloning, and unauthorized use of smart, connected industrial, medical, and consumer devices. The device also integrates the company's ChipDNA physically unclonable function (PUF) technology to prevent IC-level attacks that are routinely attempted on security ICs.
"Our latest authenticator benefits applications that require effective crypto-secure challenge-and-response authentication for securing peripherals, sensor data, usage control, and feature setting," says Scott Jones, managing director, Embedded Security, at Maxim Integrated. "Fortified by the SHA3-256 cryptographic engine and ChipDNA PUF technology, the DS28E50 provides industry-leading security to protect our customers' equipment."
Other features include single-contact, 1-Wire communication and secured EEPROM for end-application data with multiple configurable and irreversible memory-protection modes. No device-level firmware development is required (firmware is needed for the host-side microcontroller). A factory programming service is available for simplified secure key management.
The IC operates from 3.3V over -40°C to +85°C, and includes ±8kV human-body model (HBM) electrostatic discharge (ESD) protection. It is housed in a 6-pin, 3 x 3-mm TDFN package.
The DS28E50 is available now for $0.97 (1000-up, FOB USA). An evaluation kit - the DS28E50EVKIT# - is available for $65.
