Briefing

Distributed systems struggle to achieve robust, transparent temporal ordering without relying on trusted authorities or synchronized clocks. This research introduces Affine One-Wayness (AOW), a new post-quantum cryptographic primitive based on iterative polynomial evaluation over finite fields. AOW provides strong temporal binding guarantees, reducing its security to hard problems in hyperelliptic curves and affine iterated inversion. This primitive enables Byzantine-resistant event ordering and distributed synchronization with provable security, fundamentally enhancing the reliability and security of future decentralized architectures against quantum threats.

Context

A persistent challenge in distributed systems involves establishing verifiable temporal ordering without central authorities or synchronized clocks, a problem exacerbated by the looming threat of quantum computing which undermines many current cryptographic assumptions. Existing methods often compromise on transparency or rely on trust, leaving systems vulnerable to manipulation or requiring complex, inefficient coordination protocols for timestamping and event sequencing.

Analysis

Affine One-Wayness (AOW) functions as a cryptographic primitive that creates a verifiable, time-bound link to data through repeated polynomial evaluations. Conceptually, one applies a specific mathematical function iteratively to an input, and the difficulty of reversing this process or finding a shortcut provides the temporal security. This method fundamentally differs from prior approaches by leveraging the computational hardness of problems related to high-genus hyperelliptic curves and affine iterated inversion, offering post-quantum security guarantees for temporal verification. Its transparent setup and efficient integration with STARK proof systems allow for scalable, zero-knowledge verification of sequential computations.
