Hybrid Homomorphic Encryption Faces Usability and Security Challenges

/ 1 min read

🔒✨ Hybrid Homomorphic Encryption (HHE) faces usability and security challenges despite advancements. A recent report analyzes key HHE schemes, including PASTA, HERA, and Rubato, implemented in Go to assess their performance in client-server environments. While these schemes show promise, the study highlights vulnerabilities to practical attacks, despite meeting theoretical security standards. The authors advocate for enhanced security measures, such as standardized parameter sets and noise addition techniques, to mitigate these risks. Their findings aim to guide researchers and practitioners in developing more secure and efficient HHE systems, ultimately facilitating broader adoption in real-world applications. The implementation details are publicly available on GitHub to promote open science and reproducibility.
