CryptoAuthentication Memory Tokens by Nexus Industrial Memory are token-based authentication solutions that utilize Microchip's ATSHA204A and ATECC608A high security hardware authentication ICs integrated into portable memory devices. These tokens integrate security functions for dedicated applications, combining authentication capabilities with EEPROM storage functionality. The tokens are designed for secure storage and transfer of cryptographic keys, certificates, and passwords, serving as secure credentials for various authentication applications. The system works with both board-mount and panel-mount receptacles, with board-mount models available in surface-mount and through-hole versions.
