PIRonGPU

PIRonGPU is an innovative library that accelerates data retrieval while preserving user privacy through the implementation of Private Information Retrieval (PIR) technology. By modifying the existing SealPIR protocol with HEonGPU, PIRonGPU leverages the parallel processing capabilities of GPUs to perform computation-intensive tasks at significantly higher speeds. This approach not only ensures that the client’s data request remains confidential but also enhances performance in high-demand applications. With its modular and flexible design, PIRonGPU offers a secure and efficient solution for modern data querying needs, making it an ideal tool for applications requiring both privacy and high-performance computing.
