FuseFSS: Revolutionizing Secure Inference with Speed and Efficiency

field of AI, secure inference remains a challenging frontier. Two-server secure inference allows clients to interact with large language models (LLMs) while keeping their inputs confidential. Recent advancements in GPU systems have made strides in this area, particularly through function secret sharing (FSS). However, key hurdles remain. Nonlinearities and helper operations in fixed-point calculations often slow down performance. This is where FuseFSS enters the scene.

What FuseFSS Brings to the Table

FuseFSS isn't just another incremental improvement. It's a game-changing compiler that replaces the need for bespoke protocol designs for each operator with a streamlined compilation pipeline. For every scalar fixed-point operator, FuseFSS provides a compact specification. This includes its interval partition, low-degree arithmetic pieces, and required predicate bits. The result? Two batched FSS evaluations on the public masked value that significantly enhance performance.

The benchmark results speak for themselves. FuseFSS achieves a 1.24 to 1.50 times speedup in end-to-end processing on BERT and GPT-style models compared to current state-of-the-art FSS-based GPU secure inference systems. Moreover, it reduces online communication by 9% to 16%, which is nothing short of impressive.

Preprocessing Gets a Boost

But that's not all. FuseFSS also lightens the preprocessing load. The key-generation time sees a 14% to 23% reduction, and the keys themselves are 20% to 24% smaller. This not only enhances efficiency but also lowers the barrier for adopting secure inference.

So, why should readers care? As AI models continue to grow in size and complexity, the ability to perform secure inference efficiently becomes essential. Without innovations like FuseFSS, the computational and communication overheads would make secure inference impractical for many applications.

A Paradigm Shift in Secure Inference

What the English-language press missed: FuseFSS isn't just about improving numbers. It's about redefining the secure inference paradigm. By simplifying the protocol design process and enhancing performance metrics, FuseFSS makes secure inference accessible and practical at scale.

Isn't it time the tech world paid more attention to such advances? With FuseFSS setting the stage, we might soon see faster, more efficient, and more secure AI applications across industries. The data shows it's not just possible, it's already happening.
