Title: Isamu Fukuda: Innovator in Cryptographic Technologies

Introduction

Isamu Fukuda is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of cryptography, holding a total of 9 patents. His work focuses on enhancing data security through innovative transmission systems and cryptographic methods.

Latest Patents

Fukuda's latest patents include a transmission system, transmission method, and encrypting apparatus. In his first transmission apparatus, a first head encryption unit encrypts a head block of first plain text using an ID. A non-head encryption unit encrypts a block using the preceding encrypted block. A first transmitter transmits the first encrypted data and the ID to a second transmission apparatus. A first holding unit holds the end encrypted data. A second head encryption unit encrypts a head block of second plain text using the end encrypted data. A second transmitter transmits the second encrypted data generated by the second head encryption unit to the second transmission apparatus. In the second transmission apparatus, a first decryption unit performs decryption on the first encrypted data using the ID. A second holding unit holds the end encrypted data included in the first encrypted data. A second decryption unit decrypts the second encrypted data using the end encrypted data.

Another notable patent is for an apparatus and method for performing different cryptographic algorithms in a communication system. This communication apparatus performs encryption on data transmitted from another communication apparatus by using either a first or second cryptographic algorithm. It can also perform decryption on the data that has been encrypted using the first or second cryptographic algorithm. The second cryptographic algorithm provides a higher security level than the first. The communication apparatus includes an encryption unit configured to perform encryption or decryption based on the cryptographic class identifying a parameter to be used.
