"The SAES offered on STM32U85xx is based on which clock system? Which documents refer and provide more information?"
You mean the STM32U575/585 series?
SAES?

oui bien sur, petite erreur de frappe.

Hi @lbouc.2 ,
can you explain what you mean by "clock system"?
According to the reference Manual , SAES uses 2 clocks signals:
You can find more informations about these clocks in reference Manual of STM32U5 Series : https://www.st.com/en/microcontrollers-microprocessors/stm32u5-series.html#documentation

Hello @diane POMABIA ,
thanks for your answer.
After more research, I dont't understand the execution times that I get.
In fact, when I executing an AES-128 in mode ECB, I get a time of 19 µs for the encryption.
And when I executing an SAES-128 in mode ECB, I get a time of 58 µs for the same encryption.
So, I don't undertand why I find a time multiplied by 3, whereas I find in the manuel a coefficient of 10 (as you can see in the picture).
I am attaching the sources files which make it possible to obtain the times that I have indicated.
Sorry for my english, it's not my native language.
