ETRI Develops Next-Generation Security Technology... "Strengthening Data Sovereignty"

Next-generation security technology to strengthen personal data sovereignty has been developed in Korea.

The Electronics and Telecommunications Research Institute (ETRI) announced on the 8th that it has developed the "Trust Data Connectome Technology," a personal data trusted distribution platform to guarantee personal data sovereignty.

This technology is significant in that it establishes a foundation for individuals to safely and efficiently manage their own data, moving away from the corporate-centered data management environment that has been prevalent so far.

ETRI first made a breakthrough in improving the efficiency and security of neural network learning-based encryption technology. This means that technology enabling the exchange of data encryption keys without a trusted authority has been secured. The Connectome technology can complete encryption key exchange within 320 milliseconds (ms), making it highly applicable for everyday use.

ETRI also proposed a method to verify validity without data leakage during data transactions between individuals by developing a "Trust Data Validity Verification Model" utilizing zero-knowledge proof. This model allows the selection of verification levels according to the importance of the data, providing the advantage of guaranteeing the reliability of data transactions without a trusted authority.

According to ETRI, this enables the application of verification levels based on the sensitivity and scope of use of personal-generated data such as healthcare data and automobile driving data during transactions, allowing efficient data trading while further enhancing security levels.

In particular, to improve the safety of the distributed structure for strengthening personal data sovereignty, ETRI identified vulnerabilities in the blockchain network and confirmed the possibility of partitioning attacks on the Ethereum network. They also completed a network patch in collaboration with Ethereum developers.

The results of this research were presented at the Network and Distributed System Security Symposium (NDSS), the top international conference in the security field, and were recognized externally for excellence, including being selected as excellent software at the international conference ACSAC.

Kim Jeong-nyeo, head of ETRI's Cybersecurity Research Division, said, "ETRI leads safe information security technology and strives to protect personal data and drive quantum security innovation. We expect these efforts to contribute to building a sustainable data ecosystem in the future and provide a core foundation for the development of the future data industry."
