We would like to use the embedded Jetson TRNG engine for random data.
Where can we find information on the source of randomness and what certifications (or qualifications) it has?
For example in comparison to TPM modules etc.
Benchmarks and expected performance?
here’s sample application, OP-TEE hwkey-agent.
the CA sample program named 'hwkey-app' that is intended to work with the 'hwkey-agent' TA to provide encryption and decryption function with the keys provided by TA.
Thank you very for the prompt response.
Is there any (significant) different between Xavier AGX and NX modules with regard to TRNG performance?
Would it be also supported on earlier JP versions like 4.6.2 for example?
FYI,
there’s trusted execution environment update; JP-4.x release keep using Trusty, but JP-5.x release moving to OP-TEE.
to be honest, I don’t have numbers for comparison results.
however, it’s SE clock for security engine.
SE running at 115.2MHz (the min rate of SE) by default, the max rate of SE is 1GHz.
you may tune the clock to have better crypto performance. # echo <clock_rate> > /sys/kernel/debug/bpmp/debug/clk/nafll_se/rate
