Title: Seonghan Shin: Innovator in Encryption Technologies
Introduction
Seonghan Shin is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of encryption technologies, holding 2 patents that showcase his innovative approach to secure data processing.
Latest Patents
His latest patents include an encryption processing system and an authentication system for mutual authentication. The encryption processing system involves a first device that generates synthesis keys by selecting public keys of second devices. It also generates intermediate texts from confidential texts and creates ciphertexts by further encrypting the intermediate text. The system ensures that each second device verifies the validity of the ciphertexts and generates decryption key fragments using its own private key. The third device plays a crucial role in verifying the validity of these fragments and generating a decryption key to restore the secret information.
The authentication system is designed for mutual authentication between a terminal and a server. It features a memory means that pre-stores authentication information and utilizes a specific calculation formula to yield values for secure communication. This system enhances security by ensuring that both the terminal and server can generate master keys based on shared information and random numbers.
