Abstract
The device verification system according to the present disclosure includes a plurality of devices and a communicator which manages the devices, wherein each of the plurality of devices includes a security function means, hash values of components and programs generated at the startup of each device are stored in each security function means, and the communicator comprises a verifying means that verifies the authenticity of each device at the startup on the basis of the hash values stored in the security function means and an output means that outputs the result of the verification.
Claims21
A device verification system including a plurality of devices and a communication device that manages the devices, wherein
- each of the plurality of devices includes a security function unit, a hash value of a component and a program generated at a time of activation of each of the devices is stored in the security function unit, and
- the communication device comprising:
- a memory storing instructions;
- and
- at least one processor configured to execute the instructions to:
- perform verification of authenticity of each of the devices at the time of activation in accordance with the hash value stored in the security function unit, and
- output a result of the verification.
A device verification method comprising:
- by a communication device that manages a plurality of devices,
- the step of performing verification of authenticity of each of the devices at a time of activation in accordance with a hash value of a component and a program generated at a time of activation of each of the devices, the hash value being stored in a security function unit of each of the plurality of devices;
- and
- the step of outputting a result of the verification.
A non-transitory recording medium that stores a program for causing a computer to execute:
- the step of performing verification of authenticity of each of devices at a time of activation in accordance with a hash value of a component and a program generated at a time of activation of each of the devices, the hash value being stored in a security function unit of each of a plurality of devices;
- and
- the step of outputting a result of the verification.
