QIMEN-suite

The QIMEN (Quaternion and Isogeny Machinery over ENdomorphism ring) cryptographic suite represents a comprehensive, next-generation framework designed to secure digital infrastructures against both classical and quantum adversaries. The suite is composed of two primary building blocks: a key-encapsulation mechanism, designated as QIMEN-PIKE, and a digital signature scheme, designated as QIMEN-PRISM. Both schemes are constructed upon the foundational hardness of the supersingular isogeny path and endomorphism ring problems, which have emerged as resilient mathematical paradigms within post-quantum cryptography.

name

Qimen Dunjia (奇门遁甲) is an ancient Chinese system that combines divination, cosmology, and strategic decision-making. Traditionally used to analyze timing, direction, and the dynamics of a particular situation, it has historically been associated with military strategy and the selection of favorable times and directions.

The name Qimen Dunjia roughly means "Mysterious Gates and the Hidden Jia," reflecting the idea of concealment at the heart of the system. It uses a symbolic nine-square chart to represent the interplay of time, space, direction, and various natural and cosmic forces, helping practitioners understand the hidden dynamics of a situation and decide when to act, where to move, what to avoid, or when to remain concealed.

In Chinese popular culture, especially in martial arts and fantasy stories, Qimen Dunjia is often portrayed more dramatically as a mysterious art of formations, concealment, escape, misdirection, and manipulating one's surroundings.

Besides, 奇 (Qi) echoes the middle character in the Chinese translation of "supersingular" (超奇异).
