Title: Innovations of Kitak Kim in Semiconductor Technology

Introduction

Kitak Kim is a prominent inventor based in Yongin-si, South Korea. He has made significant contributions to the field of semiconductor technology, holding a total of three patents. His work focuses on enhancing the functionality and security of semiconductor devices.

Latest Patents

One of Kitak Kim's latest patents is a semiconductor device that includes a secure patchable ROM and a method for patching a patchable function programmed in a read-only memory (ROM). This innovative method involves using firmware loaded onto a first memory, which includes receiving an encrypted and digitally signed firmware image. The process generates a verification result by verifying the firmware image using a public key, decrypting the firmware image with a secret key based on the verification result, and loading the decrypted firmware onto the first memory. When the patchable function is called, a replacement function corresponding to an identifier of the patchable function included in the firmware is executed.

Another notable patent is an authentication apparatus based on a public key cryptosystem, which is integrated into a device supporting network communication. This apparatus includes a certificate handler that receives and verifies the certificate of an opponent. The cryptographic primitives generate a random number in response to an authentication request, create a challenge corresponding to that random number, and verify the opponent's response. A shared memory stores the parsed certificate, random number, challenge, and response, while an authentication controller manages the components according to an authentication protocol.
