Researchers Unveil Urgent Secure Scheme for Neural Network Inference

BREAKING NEWS: A groundbreaking privacy-preserving scheme for secure neural network inference has just been unveiled by researchers from Southeast University and Purple Mountain Laboratories. This urgent development addresses critical privacy concerns as more users rely on cloud services for processing sensitive data, which is often vulnerable to unauthorized access.

The study, titled “Efficient Privacy-Preserving Scheme for Secure Neural Network Inference“, proposes an innovative approach utilizing homomorphic encryption and secure multi-party computation. This new scheme is designed to protect both user data and cloud server models simultaneously, ensuring fast and accurate inference without compromising security.

Key improvements in the scheme streamline the inference process across three stages: merging, preprocessing, and online operations. The researchers have also introduced a novel network parameter merging technique, significantly reducing the number of multiplication levels required. Additionally, a fast convolution algorithm enhances computational efficiency, making this scheme one of the most advanced in the field.

Leveraging the CKKS homomorphic encryption algorithm, the researchers achieved remarkable results on the MNIST and Fashion-MNIST datasets, with inference accuracy rates of 99.24% and 90.26%, respectively. Compared to existing methods like DELPHI, GAZELLE, and CryptoNets, this new scheme reduces online-stage linear operation time by at least 11%, cuts online-stage computational time by about 48%, and decreases communication overhead by 66%.

Researchers Liquan CHEN, Zixuan YANG, Peng ZHANG, and Yang MA emphasize the significance of their findings in enhancing data security in an increasingly digital world. With more devices connected to the internet, safeguarding user privacy and sensitive information has never been more critical.
