Dr Mike Pound explains the suspected backdoor in the Dual_EC_DRBG random number generator and how elliptic curve constants could let someone predict its output.

HN points to it as an intuitive explanation of how NIST standardized a backdoored generator.

@qzx_pierri2025 · in “NIST selects HQC as fifth algorithm for post-quantum encryption”

I recommend this video by Computerphile - He talks about how NIST may have been pressured into enforcing compromised (backdoored?) cryptography methods as a standard - Dual_EC_DRBG to be exact. He also gives a super cool/intuitive breakdown on how this came to be. It will definitely grow some food for thought. ▶ this video

Computerphile video discussing the mathematics around how such a number could have been used in a practical way. ▶ this video link When people say, “Don’t roll your own crypto,” it’s because the field is littered with footguns and (to stretch an analogy) guns in cryptography launch explosives.

Long story short is that we don't know for sure, but there are some possibilities that's makes it plausible ▶ this video

@Arkanum2021 · in “The NSA's Backdoor in Dual EC”

Computerphile[1] did a video about the specifics of the backdoor in Dual EC DRBG. As i understand it, the hackers replaced a magic number Q with a different value than the standards compliant one, where they had pre-computed P. [1]: ▶ this video
