Prof. Chun, Jeong-hee has decrypted the multiple linear function, the biggest challenge in the field of cryptology, for the first time in the world; developed 'HeaAn', a homomorphic encryption software program that can calculate real numbers without decryption in encrypted state; and suggested a new paradigm of security in the age of the 4th industrial revolution, being acknowledged to be an authority in the field of cryptology.

The homomorphic encryption, which enables it to conduct arbitrary calculation without decryption in a state of encrypted data, is a groundbreaking research field that has changed the topography of cryptology after the technical possibility was proven in 2009 since the start of research in the 1970s.

In comparison to the conventional homomorphic encryption that efficiently conducts calculation of specific finite field, the homomorphic encryption program (HeaAn) developed by Prof. Chun, Jeong-hee’s research team can efficiently calculate encrypted real numbers, bringing a breakthrough to homomorphic encryption. HeaAn was demonstrated for the first time in the world at ‘International Conference on the Standardization of Homomorphic Encryption’ held in Boston, the USA in Mar last year, gaining a great public favor.

As the fact that homomorphic encryption for the calculation of real numbers can be applied to all fields requiring data security, such as sensitive biometric information and financial information of individuals, has been proven, it is expected to be widely used in the future as a next generation encryption system that will lead the age of the 4th industrial revolution represented by big data, block chain, autonomous vehicle and Internet of Things (IoT), etc.
