ESM-05: Anti-counterfeiting Embedded Security Module

The ESM-05 Anti-Counterfeiting Embedded Security Module (ESM) is a low gate count, low power identity module that incorporates a unique 256 bit identifier specific to the SoC. The unique identifier is bound to a RSA private key during a user-controlled configuration process to support a variety of identity provisioning schemes. The RSA private key may only be exported as a wrapped key blob using an internal NIST AES key wrap function. Wrapping permanently binds the RSA private key to the module that created it.

Key Features:

• Secure identity module with factory-programmed unique device identifier
• Low active power consumption and auto stand-by mode
• Key import and export functions using NIST AES Key Wrap function
• Internal key generation for symmetric and RSA keys
• Flexible support for Identification and Authentication protocol based on RSA at 1024, 2048 and 3072 bit key sizes
• AMBA/AHB interface

Applications:

• Secure device identifiers
• Identification & Authentication protocol processors
• Cryptographic protocol accelerators
• Secure transaction processing
• Key management systems
