URGENT UPDATE: A groundbreaking study from a team at Southeast University and Purple Mountain Laboratories has just been released, unveiling a revolutionary privacy-preserving scheme for secure neural network inference. This innovative approach addresses critical security concerns for users relying on cloud services for sensitive data processing.
In an era where data breaches are rampant, this new scheme utilizes homomorphic encryption and secure multi-party computation to protect user data and cloud-stored model parameters. The research team aims to ensure that both users and cloud servers can operate securely while maintaining fast and accurate processing of encrypted data.
The study, titled “Efficient Privacy-Preserving Scheme for Secure Neural Network Inference,” introduces an optimized inference process split into three stages: merging, preprocessing, and online. This design not only streamlines operations but also enhances computational efficiency significantly.
Using the CKKS homomorphic encryption algorithm, the scheme merges consecutive linear layers to minimize communication rounds and computational costs. It effectively transforms convolutional operations into matrix-vector multiplications, making full use of ciphertext slots.
The results are impressive. Experiments conducted on the MNIST and Fashion-MNIST datasets demonstrate a staggering 99.24% inference accuracy for MNIST and 90.26% for Fashion-MNIST. Compared to leading methods like DELPHI, GAZELLE, and CryptoNets, this scheme reduces online-stage linear operation time by at least 11%, computational time by approximately 48%, and communication overhead by 66%.
The implications are vast. Users can now process sensitive data without the fear of unauthorized access, marking a significant advancement in the field of cybersecurity and cloud computing. As smart devices and cloud services proliferate, the need for such security measures has never been more pressing.
With this innovative scheme, researchers are paving the way for a safer digital environment. The paper is authored by Liquan CHEN, Zixuan YANG, Peng ZHANG, and Yang MA.
