We've expected that lattice KEMs would only be used in hybrid combination with establish elliptic curve key exchanges, which ameliorates any weakness in the lattice KEM. In particular, there exist worse side channel attacks upon lattice KEMs than upon elliptic …
i want to create formal verification for my rust project. i see that signal uses hax to extract rust code into F\* when searching online it looks like Coq seems popular, but i dont know enough to understand why signal …
I ve a loop applying y_tmp=y y=x x=y_tmp+((x+c[i])^5)%21888242871839275222246405745257275088548364400416034343698204186575808495617 219 times, where `x` and `y` are longint inputs and `c` is a static array of 220 255-bit integers. I would like to find an input `y` given an input and an …
We're a group of researchers and have just prepared a draft addressing a gap in cryptographic custody for autonomous agents. The problem: agents executing autonomously need key custody, but are the least trustworthy entities to hold keys alone. Existing solutions …
I’ve published an experimental symmetric construction and would appreciate technical critique. GitHub: [https://github.com/alt160/Zifika](https://github.com/alt160/Zifika) # Model summary Zifika is a deterministic keyed path-walking cipher defined over a 2D permutation grid: * The key consists of `N` rows, each a permutation of …
