se052f mbedtls fips140-3

Hi,

I have a doubt regarding about the FIPS140-3 certification maintenance in the secure element SE052F. MbedTLS doesn't have a FIPS certification. However, the document AN12543 specifies which applet features must be set and which must be disabled in order to maintain the certification, and there is no specific mention about mbedTLS. According to AN13030, it says that enabling mbedTLS ALT allows mbedTLS stack to use the secure element cryptographic functions.

Could you confirm if the FIPS 140-3 certification is maintained when you use the MbedTLS library and enable mbedTLS ALT?

Hi @ar01 ,

MbedTLS library is running on the host not SE, so whether you use MbedTLS or not doesn't affect the FIPS maintenance , just make sure the applet features within SE052F are configured correctly according to AN12543 , that is what we configure it for FIPS140-3 certification.

Hope that makes sense,

Have a great day,
Kan
