| # Using SE05X for crypto operations |
| |
| ## Introduction |
| |
| CHIPCryptoPALHsm_SE05X.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 role) operations. |
| |
| Following table shows the operations supported by secure element. |
| |
| +-------------------------+-----------+----------------+---------------------------------+------------+----------------------------+ |
| | Operation | Software | Default config | Note | Re-entrant | Directive to |
| enabled in | | | fallback | value | | | CHIPCryptoPALHsm_config.h | |
| +-------------------------+-----------+----------------+---------------------------------+------------+----------------------------+ |
| | SPAKE Verifier | No | Enabled | - | No | ENABLE_HSM_SPAKE_VERIFIER | |
| +-------------------------+-----------+----------------+---------------------------------+------------+----------------------------+ |
| | SPAKE Prover | No | Enabled | - | No | ENABLE_HSM_SPAKE_PROVER | |
| +-------------------------+-----------+----------------+---------------------------------+------------+----------------------------+ |
| |
| ## Build |
| |
| - Use the following gn build arguments to enable the secure element in crypto |
| layer, |
| |
| ``` |
| smcom=\"t1oi2c\" chip_with_se05x=1 |
| ``` |
| |
| ## Known Limitations: |
| |
| - None |
