Title: Shigeto Akutsu: Innovator in Encrypted Communications

Introduction

Shigeto Akutsu is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of encrypted communications, holding a total of 2 patents. His work focuses on methods that enhance the security and efficiency of data transmission.

Latest Patents

Akutsu's latest patents include a "Method for synchronization in encrypted communications using shared key" and a "Method and system for encrypted communications using multi-valued modulation." The first patent describes a synchronization method for a running key generated from a shared key, which is essential for encryption and decryption in communications. This method involves the transmitting node sending a multi-valued signal with a fixed pattern before transmitting encrypted data. The receiving node then generates a bit discrimination threshold signal to ensure proper synchronization between the nodes.

The second patent outlines a system where a transmitting node produces synchronization data to be inserted into plaintext, which is then encrypted into multi-valued data for transmission. The receiving node decrypts the signal and confirms synchronization of the running key, ensuring secure communication. If synchronization is lost, the system allows for re-synchronization to maintain data integrity.
