Maxim Integrated's DS28E25G+T: Secure Authenticator IC
The DS28E25G+T from Maxim Integrated is a robust secure authenticator that provides a core set of cryptographic tools derived from integrated asymmetric (ECC-P256) and symmetric (SHA-256) security. This device is designed to ensure the authenticity and integrity of products by enabling unclonable device identity. It can be used in a wide range of applications, including medical sensors and tools, IoT devices, consumable authentication, embedded systems, and peripheral device authentication.
Key Features
- Advanced Security: The DS28E25G+T employs a FIPS/NIST compliant secure hash algorithm (SHA-256) and elliptic curve digital signature algorithm (ECDSA) to provide strong cryptographic security.
- Memory: It includes 3KB of user-programmable EEPROM, partitioned into pages that can be individually set to be read-only or secret.
- ChipID™: A unique and unalterable factory-programmed 64-bit identification number enhances security and traceability.
- Communication: Utilizing the 1-Wire® protocol, the device requires only a single contact for communication and can be powered through the data line (parasite power), minimizing the need for additional power supply lines.
- High Integration: The device integrates a hardware-based secure storage and provides a turnkey solution for secure cryptographic key storage that can be easily integrated into customer applications.
Applications
- Medical Device Authentication
- Secure Peripheral Management
- IoT Device Security
- Accessory and Consumable Authentication
- Embedded Security
