Maxim Integrated DS28E50 DeepCover Secure Authenticator

The DS28E50 from Maxim Integrated is a robust security solution that combines crypto-strong authentication with a FIPS/NIST true random number generator, and secure storage. This device is designed to offer a cost-effective way to add tamper-evident and counterfeit-resistant features to a wide range of equipment, including medical devices, IoT endpoints, and consumable goods.

Key Features

• Robust Security: The DS28E50 utilizes ChipDNA™ physically unclonable function (PUF) technology, which provides an inherent defense against invasive physical attacks. The cryptographic keys derived from the ChipDNA block are never stored in memory or communicated over a bus, ensuring that the keys are not susceptible to theft.
• Secure Authentication: With its SHA-3 cryptographic engine, the device supports secure challenge and response authentication, making it extremely difficult for unauthorized parties to gain access to sensitive areas of the system.
• High-Quality Random Number Generation: The built-in FIPS/NIST compliant true random number generator is essential for creating cryptographic keys and for other security-related functions.
• Easy Integration: The DS28E50 is designed with a simple single-contact 1-Wire® interface, which facilitates easy integration into designs that require minimal interconnect to the host microcontroller.
• Secure Storage: It provides secure storage for sensitive data, including system-level security tokens and keys, ensuring that critical data remains protected.

Applications

• Medical Device Authentication
• IoT Device Security
• Peripheral Security
• Secure Boot
• Supply Chain Integrity
• Consumables Authentication

The DS28E50 is a powerful addition to Maxim Integrated's DeepCover® lineup of secure microcontrollers and authenticators. Its advanced security features make it an ideal choice for designers looking to enhance the integrity and security of their products without significantly increasing cost or complexity.
