      So, the problem with USB tokens that we basically have two choices: - Unauditable black boxes built on *supposedly* more secure ICs that require NDAs to develop for - Open and auditable, but definitely pwnable off the shelf microcontrollers. Which poison do you prefer?

      Open IC, because of you master assembly language and code everything with it, you can code things that can resist usual pwn techniques.

      No. Coding in assembler has nothing to do with writing secure software (in fact it's a lot worse most of the time), and certainly has nothing to do with the physical attacks I'm talking about, which cannot be mitigated in any programming language.

          I was not talking about processor security breaches, or other lab attacks. I master assembly language, more than 1.3 million lines coded and debugged so far, and I can ensure you I know how to code securely like no other high level language can do.

          For example, in assembly language, there are technics from assembly language jedi knights like me to mitigate stack & buffer overflow, but also ROP and maybe JOP (I'd have to review JOP's white paper to ensure my tricks can work). It's all a matter of being an advanced highly

          Or you could just code in Rust and never have to worry about buffer overflows. Sorry, I would never hire you. You don't know what you're talking about if that's your mindset. If you think coding in assembler means you write more secure code, I am certain your code is not secure.

          trained coder or not. These tricks are coding constraints, that very few people master, but they exist.
