Encryption Breakthrough Enables Privacy-Preserving AI with Orion Framework

Researchers Austin Ebel, Karthik Garimella, and Brandon Reagen have developed Orion, a novel framework enabling fully homomorphic encryption (FHE) in deep learning, allowing AI models to operate on encrypted data without decryption.

Published on arXiv and set to be presented at the 2025 ACM International Conference on Architectural Support for Programming Languages and Operating Systems, Orion addresses challenges in computational overhead and neural network adaptation for FHE, achieving a 2.38x speedup over existing methods on ResNet-20 and demonstrating high-resolution object detection with YOLO-v1, a model 500 times larger than ResNet-20.

The framework’s lightweight design lowers the barrier to entry for implementing FHE in real-world applications, benefiting privacy-sensitive industries like healthcare, finance, and cybersecurity. By enabling confidential data processing without compromising user privacy, Orion advances practical deep learning applications while maintaining security.
