Seed for Deterministic Random Bit Generator

KhanhLe — Thu, 24 Feb 2022 08:16:22 GMT

Hello NXP support,
I have some requirement below but I can't find any information related to this. Could you help me about it?
Does that meet below requirement:
· Entropy: At least 7.5 bits per character or higher.
· Compression: 0%
· Chi-Square: Between 200 and 400 and randomly exceed more than 10% and less than 90% of the time.
· Mean value: Between 126 and 128
· Monte Carlo: Max 0.5% error
· Serial correlation: 0.1 or lower

Hi,

finally I got more details. In short, yes, RNG4 used in HSE will meet the requirements.

But the requirements seems to be obsolete. Our RNG was designed to meet the new/modern requirements given in SP800-90[AB] and BSI AIS 20/31.

Lukas

Hello @lukaszadrapa,

Could you give me a test report or evidence to cover the requirements given in SP800-90[AB] and BSI AIS 20/31(for S32K11x).

Best regards,
