Title: Hiroyuki Tsukamoto: Innovator in In-Vehicle Network Detection Technologies
Introduction
Hiroyuki Tsukamoto is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of in-vehicle network technologies, particularly in the detection of unauthorized messages. With a total of 2 patents, Tsukamoto's work is pivotal in enhancing vehicle security.
Latest Patents
Tsukamoto's latest patents include a detection device, detection method, and detection program aimed at identifying unauthorized messages within in-vehicle networks. The first patent describes a detection device that detects the presence of an unauthorized message by utilizing a state detection unit. This unit monitors the transition to a state where periodic messages are transmitted, analyzing the content of messages in the network. The processing unit then performs detection processing based on the reception status of multiple periodic messages.
The second patent also focuses on a detection device that monitors both periodic and event messages in an in-vehicle network. This device includes a monitoring unit that tracks messages with assigned identification information and sequence numbers. A counter unit adjusts the counter value corresponding to the identification information upon receiving an event message. The detection unit then compares the sequence number with the counter value to determine the presence of unauthorized messages, ultimately making conclusive determinations based on message intervals and transmission cycles.
