Hello Andy,
In Nordic we use/implement the PSA APIs but we don't own them, no. The people who own the PSA APIs are mainly people from ARM.
I guess that you can implement the PSA APIs by yourself by following the spec here: https://github.com/ARM-software/psa-api
But then you will have to make sure that you are compliant to the spec yourself.

Hi Georgios,
Thanks for your information. Actually, the files we had read and the API wrapper is based on the mbedTLS. We can not easily to integrate with our Hardware Crypto Engine or not support API. So we found the PSA Crypto API is more filexable or add customeizer API.
It means we need to know if using the PSA Crypto API directly is possible or if there are other ideas based on your experience.
BTW, you are based on NORIC, so that means the PSA Crypto API is handled by NORDIC!
Thanks,
Have a Nice Day, Andy ________________________________ 寄件者: Vasilakis, Georgios georgios.vasilakis@nordicsemi.no 寄件日期: 2024年8月7日 下午 04:25 收件者: psa-crypto@lists.trustedfirmware.org psa-crypto@lists.trustedfirmware.org; Andy Chen andychen@pufsecurity.com 主旨: Re: PSA Crypto API Integration
Hello Andy,
The PSA driver wrapper is the intended way of integrating to the PSA crypto APIs. There are already some drivers which you can use as a reference apart from the documents provided in the mbedtls repository.

Hi PSA Crypto Team,
This is Andy from PUFsecurity. We have a project and begin following the PSA Crypto API to integrate our Hardware Crypto Engine (PUFcc). However, we are encountering some issues and need your assistance. There are several ways to integrate:
1. Directly 2. Via mbedTLS 3. Using the PSA Crypto Driver
Currently, we are attempting direct integration. Is this a good choice, or do you have other suggestions? There are many ARM applications, such as Secure Debug and Secure Boot. Completing the integration with the PSA Crypto API will ensure compatibility with these applications. Thank you very much.
Have a Nice Day, Andy
