Title: Koken Yamamoto: Innovator in Wireless Technology
Introduction
Koken Yamamoto is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of wireless technology, holding a total of 13 patents. His innovative work focuses on enhancing security and efficiency in wireless communication systems.
Latest Patents
Yamamoto's latest patents include a wireless tag, reader/writer, encoding system, and encoding method. This invention involves an encrypted ID that takes as its initial value a tag ID, which constitutes the original ID of a wireless tag. The ID is encrypted using an encryption key each time an ID inquiry is received from a reader/writer. Additionally, another encrypted ID also takes the tag ID as its initial value and is encrypted similarly. The wireless tag provides confidential variability to the ID by transmitting a combination of the encrypted IDs in response. The reader/writer can obtain the original ID by decoding the two encrypted values until they match, ensuring that the decoding load remains manageable even as the number of wireless tags increases.
Another notable patent is a processing apparatus and integrated circuit designed to prevent illicit access and reverse engineering. This apparatus includes an internal circuit with a CPU and internal devices, as well as an external circuit with devices provided externally. The internal circuit features a ciphering section that secures addresses and data on the bus line by ciphering patterns according to various regions divided from the address space allotted to the external devices.
