CryptoLab, a company with world-leading homomorphic encryption technology, announced Monday that its generative artificial intelligence security solution "HEaaN Zero-Leak RAG" has received the highest GS certification grade — Grade 1 — from the Telecommunications Technology Association (TTA). The GS certification is a national certification system granted to products that pass comprehensive evaluations based on international standards, including functional suitability, reliability, usability, efficiency and security.
Conventional RAG technology carries the risk of exposing sensitive information during data retrieval and model inference processes. HEaaN Zero-Leak RAG, however, encrypts the core vector database with homomorphic encryption from the outset, performing similarity searches even while data remains in encrypted ciphertext form, fundamentally eliminating the risk of data leaks. The solution is recognized as the only one capable of countering embedding inversion attacks, one of the "Top 10 Vulnerabilities for LLM Applications" defined by OWASP, the international web security standards organization. Its accuracy reaches approximately 99% on average compared to plaintext processing. In high-performance computing environments, the time to first token generation averages only about 1.9 seconds.
"This Grade 1 GS certification is an official recognition of CryptoLab's unrivaled technology and stability," said Hong Jeong-dae, head of CryptoLab's business development division. "Building on this, we will actively support the safe adoption of AI in the public sector and contribute to elevating the nation's AI security standards."
CryptoLab plans to achieve major security milestones this year, using this certification as a springboard. The company aims to complete registration as an innovative prototype product with the Public Procurement Service by June to expand public sector sales channels, followed by obtaining CC certification (EAL2) for its encrypted RAG solution by September.
