DeepCover Secure Authenticator with ISO 15693, SHA-256, and 4Kb User EEPROM

Industry's First SHA-256 Symmetric Key-Based Authenticator

Product Details

DeepCover® embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible.

The DeepCover Secure Authenticator (MAX66240) is a transponder IC that combines an ISO/IEC 15693 and ISO 18000-3 Mode 1-compatible RF front-end, a FIPS 180-based SHA-256 engine, and 4096 bits of user EEPROM in a single chip. A bidirectional security model enforces two-way authentication between a host system and the MAX66240. Each device has its own guaranteed unique 64-bit ROM ID that is factory programmed into the chip. This ROM ID is used as a fundamental input parameter for cryptographic operations and serves as an electronic serial number within the application.

Key Features

  • Dedicated Hardware-Accelerated SHA Engine
  • Strong Authentication with a High Bit Count User-Programmable Secret and Input Challenge
  • 4096 Bits of User EEPROM with User-Programmable R/W Protection Options Including OTP/EPROM Emulation Mode

Description

The MAX66240 evaluation kit (EV kit) reference board is a ready-to-use PCB that showcases one of Maxim’s MAX662xx family of secure HF ICs. The board is built with a hexagonal-shaped antenna construction (see the EV Kit Photo and Figure 3 in the full data sheet) tuned to 13.56MHz.

The EV kit is a platform that allows designers, test, and systems engineers to evaluate our MAX66240 tag solution. The EV kit allows users to evaluate the performance and capabilities of certain key features of the part and is a great platform to get started on a new NFC/RFID tag design.

Features

  • HF Interface at 13.56MHz
  • User EEPROM Authenticated Memory Page Read/Write Transactions
  • User EEPROM Page/Block Read/Write Transactions
  • Secure Transaction that Writes “Secret Keys” and Computes Message Authentication Code

Description

The MAX66300-24x evaluation system (EV system) comprises a MAX66300 evaluation kit (EV kit) and a MAX66242 tag. The MAX66300 EV kit combines a RFID reader for contactless communication at 13.56MHz and a SHA-256 secure authenticator coprocessor. The RFID reader covers the ISO 15693 standard and the authenticator coprocessor is based on the FIPS 180-4 standard. The MAX66242 tag operates as a solution covering the ISO 15693 standard. By pairing the MAX66300 EV kit with the MAX66242 EV kit into an EV system, EV kit software can operate to show a secure challenge and response authentication and other part specific functionality.
