Pls suggest us possible controller for our below requirement :
My Controller ..expectation :
is this hardware stuff or this also can be achieve by coding only to any stm32 uc.

Crypto and signing can be done is software, but also has reasonably large footprint.
You should find libraries performing methods you need, and gauge size of those, as this will put a floor on the minimum viable STM32 parts.
Couple hundred bytes per second, shouldn't need hardware, hardware creates more import/export issues.
Most parts provide a small amount of OTP and a Unique ID.
New Cortex-M33 parts might have a better security focus.

Thanks a lot !!!! a bit more i wanna ask like cypher , signed or secure boot & most important can, in short , can i know just best CAN supported controller in low cost with above IoT securities .
is stm32f103c6t6 can be used as it has CAN. but is it really safe for IoT purpose as per my above mentioned securities steps, secure boot, OTP, cypher etc is possible with stm32f103.

Hello @Nverm.1 ,
You can use STM32CubeMX MCU selector to narrow down your search according to you preferences, a quick search according to your specifications gave the following MCU series. To further narrow your search you need to provide more details.

Hi @Nverm.1,
finding a device with CAN support is not difficult, to identify the right balance between cost and the security, Introduction to STM32 microcontrollers security - Application note can help.

Post / Thread is from a YEAR AGO
A lot of support is about timely responses. There are perhaps more prescient issues, and ones which could do with a wealth of worked examples.

STM32H742xI/G or STM32H743xI/G fulfils some of the criteria.

Regarding the OTP management, you can see this document.
