Try to prove that my denial protocol doesn't work

REDDIT / Mister_ZE / May 14, 2026

*A few weeks ago I started building a post-quantum encryption library. One of the protocols, which I called BLUE, is supposed to give built-in plausible deniability.* *I've been thinking about deniability for a while. I've seen VeraCrypt and it's great, …

Walsh criteria for Boolean functions as spectral sectors of one graph?

REDDIT / Obvious_Airline_2814 / May 8, 2026

I noticed a possible connection between the standard Walsh conditions for Boolean functions and the spectrum of one finite graph. In Boolean-function cryptography, balancedness, correlation immunity, and resilience are usually checked through the vanishing of low-weight Walsh coefficients. So the …
