Latest Patents

One of Masaaki Tamai's latest patents is an encrypted packet processing device. This device is capable of realizing a predetermined classification process according to a data type while reducing the burden on a processing device in a communication environment where encrypted packets of different data types exist. The device includes a block specifying section that identifies a location where information necessary for a priority level determination process is stored within an encrypted packet. A specified block decryption section decrypts only the block specified by the block specifying section, extracting the necessary information for the priority level determination process. The priority level determination section then searches a priority level information database using the extracted information as a key to determine the packet's priority level.

Another notable patent involves a communication device and system that negotiates encryption algorithms for secure communications. In this system, an encryption information determination section in the communication device negotiates an encryption algorithm with a network camera, which serves as the communication counterpart. The selected encryption algorithm varies depending on the CPU load of the communication device. If the CPU utilization rate is high, a low-load encryption algorithm is chosen, while a high-load encryption algorithm is selected when the CPU utilization rate is low. The encryption/decryption processing section then performs code processing using the chosen encryption algorithm.
