The patent filed by Toshiba Corp. describes a communication system where an edge device generates edge data and a service device utilizes this data. The edge device generates a message authentication code using a shared key with the service device and transmits communication data with the code assigned to the edge data. The service device verifies the source of the edge data by checking the authentication code using a shared key with the edge device. Additionally, the system allows for the issuance of digital signatures to groups of edge data and verification of these signatures using public keys.

Furthermore, the communication system involves key management information stored by both the edge and service devices, allowing for the generation of authentication codes for specific service devices. The system also includes the encryption of shared keys between the edge and service devices for secure communication. Additionally, a server device is connected to the edge device and service device, facilitating the transmission of communication data. The server device can respond to data acquisition requests from the service device by transmitting the requested data, including authentication codes and digital signatures, ensuring secure and verified data transmission within the communication system.
