With a remarkable total of two patents, Sakai is dedicated to advancing the secure interaction between IoT devices and service providers in a world that increasingly relies on connectivity.

Latest Patents

Sakai's latest patents focus on a "Device and Method for Mediating Configuration of Authentication Information." This innovative solution addresses the challenges faced when there is no shared authentication information between an IoT device and a service provider's device. The invention includes an intermediary device capable of authenticating legitimate access between the devices involved.

One key feature of this patent is a cipher key (CK) that is stored in both the intermediary device and the IoT device. Through SIM authentication of the IoT device's SIM card, this key acts as a master key for the services utilized. By generating a unique application key for each IoT service on the intermediary device, and then transmitting it securely to the service provider's apparatus, common keys are established as authentication information between the IoT device and the service provider. Notably, the SIM authentication process employed in this structure can effectively suppress SQN attacks arising from unauthorized requests.
