Title: Motoji Omori: Innovator in Encryption Technologies

Introduction

Motoji Omori is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of encryption technologies, holding a total of 6 patents. His work focuses on enhancing data security and efficiency in communication systems.

Latest Patents

One of his latest patents is an "Encryption communications system." This system is structured from a management device, a content key distribution device, and a plurality of terminals. It suppresses the data volume of a terminal revocation list (TRL). The management device generates and transmits a TRL formed from data that expresses terminal IDs of all terminals to be invalidated, by only a value and a position of a common bit string in the IDs, to the content key distribution device. Each terminal holds a terminal ID that includes a manufacturer ID and a serial number, and requests the distribution of a content key by sending the terminal ID to the content key distribution device. The content key distribution device refers to the TRL, judges whether the terminal ID transmitted from the terminal is that of an invalidated terminal, and if negative, encrypts and transmits the content key to the terminal.

Another significant patent is the "Encrypted data delivery system." Similar to the previous system, it is structured from a management device, a content key distribution device, and a plurality of terminals. It also suppresses the data volume of a terminal revocation list (TRL). The management device generates and transmits a TRL formed from data that expresses terminal IDs of all terminals to be invalidated, by only a value and a position of a common bit string in the IDs, to the content key distribution device. Each terminal holds a terminal ID that includes a manufacturer ID and a serial number, and requests the distribution of a content key by sending the terminal ID to the content key distribution device. The content key distribution device refers to the TRL, judges whether the terminal ID transmitted from the terminal is that of an invalidated terminal, and if negative, encrypts and transmits the content key to the terminal.
