It appears that you’re saying that PX-1000cr isn’t an example NSA backdoor or that the article breaking the cipher in the PX1000cr is incorrect?
It seems like you’re either very aware of how NSA backdoors work and you’re misleading people for some reason or you don’t know what you’re talking about, you’re being hopeful and you are ignoring the evidence that NSA inserts backdoors which can be broken by others. Assuming the latter in good faith, I’m afraid to inform you that you’re simply incorrect.
Do you dispute that the secret key for the Q Parameter in Dual EC may be recovered by anyone with a CRQC? This is assuming that they exist, and if they don’t or won’t exist, why does NSA concern themselves with pq crypto? I agree that someone stealing the key is a different effort but either could have answered your question of what the key is - so the technique is largely irrelevant, but I take your more narrow point and will engage it.
If NSA isn’t misleading us to deploy broken crypto with their pq standardia push, then they probably don’t consider the Q parameter in Dual EC to be a NOBUS backdoor. After all, by your argumentation NOBUS is forever, isn’t it?
There are other backdoored systems pushed by NSA and some are still in use. I assure you, they can be broken in a weekend by someone with the relevant computer science and mathematical background. The trick for finding it is to realize your core assumption is wrong.
One system NSA built was purpose built to trick a community of interest, and it worked. The core break is in the RNG - the RNG only generates keys from a small subset of all possible keys. The users of this system have no clue.
Do you really suggest that this kind of NSA backdoor doesn’t exist and that evidence of it means that it isn’t NSA who did it? It again seems ahistorical of you.
