So, if the PSK is stored off chip, it needs to be encrypted using a key stored on chip in OTP, and then JTAG fuses blown so the only attacks available are micro-probe or glitching. (BTW, there is a proper package on that if you're still interested. re: RE). But "Encrypting the key with a symmetric key is largely pointless in most small embedded systems that can by physically attacked." Why? would the private key not have the same issue? If you incorporate the above more clearly in the answer, I'll choose it. and thank you! | |
