Using SE05X for crypto operations

Introduction

CHIPCryptoPALHsmSE05X*.cpp file provides the integration of secure element (SE05x) in crypto layer of CHIP stack. By enabling the required directives in CHIPCryptoPALHsm_config.h header file, required crypto operations can be performed using SE05x. By default, the secure element is enabled only for PAKE (Verifier/Prover role) operations and HKDF.

Following are the list operations supported by secure element.

1. PAKE
2. ECC KEY - P256 (Disabled by default)
3. PBKDF (Disabled by default)
4. HKDF

Build

  • Use the following gn build arguments to enable the secure element in crypto layer,
chip_with_se05x=1 host = "host_k32w"

Known Limitations:

  • None
