Title:
Cascader: A Recurrence-Based Key Exchange Protocol

Authors: Anders Lindman

Abstract:

Cascader, a novel key-exchange protocol based on an iterative multiplicative recurrence over a finite field, is introduced. In contrast to standard methods, e.g., traditional Diffie–Hellman and ECC, it replaces exponentiation and scalar multiplication with layered products, achieving commutativity and deterministic pseudorandom behavior.
