TDA4VM: Can TDA4VM support Gateway, Deep Learning, and EVITA HSM full feature implementation?

Jack Cha said:

3.  Can TDA4VM support the EVITA Full HSM feature below ? Application will be development by Customer. Plz check whether TDA4VM has the relevant H/W blocks.

TDA4VM and DRA829 platforms support rough equivalence to EVITA Full HSM features, when combined with third-party HSM stack executing within Security Controller Core

 Crypto Blocks

• PKA engine supports RSA and ECDSA
• AES-128/192/256 supported
• TRNG with AES-256 CTR-DRBG conditioning
• SHA2-256/384/512 is an established standard supported in place of WHIRLPOOL hash

Programmable CPU / NVM

• Programmable Cortex-M3 security controller with dedicated 272KB isolated RAM
• The TI SDK provides black-box firmware implementing foundational security functions (Secure Boot, Firewalls, Debug, etc.)
• A third-party HSM stack can be supported that provides HSM functionality and runs alongside TI Foundational Security library
• Secure Storage can be supported with secure NVM components encrypted and store in external flash with device unique 256-bit random key (NVM not available in technology node)

Hardware Interface

• Hardware based multi-threaded secure proxy module with ability to ID host/application for secure operations

Monotonic Counters

• Up to 1024 OTP bits in Customer Programmable FROM (CPFROM) can be used to point to new Key updates + SW counters with OTP bits for anti-roll back
• In addition, dedicated OTP bits exist t prevent rollback of user bootloader and security controller firmware

Hi Jack

Quick responses on your other queries

> Can TDA4VM implement Gateway while supporting heterogeneous network such as CAN, CAN-FD, Ethernet

Yes it can.

> on behalf of DRA829V?

Can you clarify this. Are you trying to design  a multi-chip ECU with both a TDA and DRA part. Is that right?

>. Can TDA4VM support Deep Learning to implement the In-vehicle network intrusion response

High level answer yes. TDA4VM includes a DL MMA engine . No specific solutions offered as part of our SDK for network intrusion response yet.

We are offering customers ability to evaluate TDA4VM AI capabilities, you can find some preliminary details here

> Which one is right between TDA4vM and DRA9J for the above application?

Do you have a full list of peripherals needed. But based on just the above (gateway + DL) then DRA829J is suitable. I believe in another post Tyler has already clarified other differences between TDA4VM and DRA829J.

Hope this helps
