Latest Patents

Iida is credited with 1 patent: “Relay apparatus for encrypting and relaying a frame.” The invention describes a relay apparatus with a frame-relay processing unit, multiple ports, and a cryptographic processing module for each port. The modules handle encryption and decryption through general-purpose interfaces, allowing the relay-processing unit to focus on forwarding frames and helping preserve relay speed. The apparatus can also generate a different cryptographic key for each frame without requiring dynamic key-information exchange.

Career Highlights

Iida’s listed patent reflects work on integrating cryptographic processing with frame-relay systems. By assigning encryption and decryption tasks to modules associated with individual ports, the design aims to reduce the processing burden on the central relay unit.

Collaborations

Iida’s listed coworkers include Satoshi Obara and Yukihiro Nakajima.

Conclusion

Takamitsu Iida’s patent describes a relay architecture that combines frame forwarding with per-port cryptographic processing to support secure, efficient data transmission.
