CryptoLab Launches 4.5th-Generation Homomorphic Encryption-Based Search Solution

Significant Improvement in Computational Performance Compared to Previous Versions
Reduced Latency During Data Search

On May 28, CryptoLab, a startup specializing in homomorphic encryption technology, announced, "We have launched a homomorphic encryption-based search solution that remains secure even in the event of a data breach, and we will begin our full-scale entry into the global market starting with an exhibition at RSAC 2025, the world's largest security conference."

Conventional encryption technologies require decryption of data for search purposes, which introduces the risk of data leakage during this process. Homomorphic encryption technology allows data to remain encrypted even while being searched; however, it has traditionally suffered from latency issues. CryptoLab has addressed this challenge by developing 4.5th-generation homomorphic encryption.

CryptoLab's 4.5th-generation CKKS homomorphic encryption technology significantly improves computational performance compared to previous versions, achieving real-time processing capabilities even in mobile environments. It also maintains the high level of security characteristic of traditional homomorphic encryption. As a result, even critical data such as biometric information, personal data, and internal or confidential information can now be used practically without concerns of data leakage, even as the adoption of artificial intelligence (AI) increases.

CryptoLab showcased its flagship product incorporating this 4.5th-generation homomorphic encryption technology, the ES2 (Encrypted Similarity Search) solution, at RSAC 2025. The solution enables a variety of vector-based and keyword-based searches?such as similar image search, facial recognition, and text matching search?to be performed in an encrypted state, making it possible to process information without decryption. CryptoLab is accelerating its efforts to enter the global market with this solution.

This technology was introduced on May 4 at Eurocrypt 2025, an international cryptography conference held in Madrid, Spain. CryptoLab presented related research papers and received academic recognition for its innovations in both performance and architecture.

A CryptoLab representative stated, "Based on this technology, we are proposing a data security model from a 'Zero Trust' perspective. Now is the time for a practical security transformation centered on encryption technologies," adding, "Recognizing that hacking can occur at any time, it is time to adopt encryption-based security that can protect the data itself."
