Title: Yongha Son: Innovator in Identity-Based Encryption
Introduction
Yongha Son is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of encryption technology, particularly in identity-based encryption methods. With a total of 2 patents, his work focuses on enhancing security through innovative computational techniques.
Latest Patents
Yongha Son's latest patents include an "Identity-based encryption method based on lattices," which discloses a calculation device. This device comprises a memory that stores at least one instruction and identity information, along with a processor that performs the instructions. The processor is capable of randomly sampling small elements, generating a function-processed output value from the stored identity information, and creating an encrypted text for a message using a master public key. This key is computed using a ring with a dimension represented by a power of 2 and an integer multiplication of 3 or more, along with the sampled small elements and the function-processed output value.
Another notable patent is the "Methods of generating encryption key and digital signature based on lattices." This method involves receiving a message and computing a particular solution, where the result of calculating this solution in a public key becomes a function-processed output value predetermined in the received message. The method then generates digital signature information for the message using the computed particular solution, with the public key also computed using a ring having a dimension represented by a power of 2 and an integer multiplication of 3 or more.
