Abstract
An electronic device which generates and authenticates identification information of a hardware device and an operation method thereof are disclosed. The operation method of the disclosed electronic device includes determining identification information used for authentication of a hardware device using a public key of the hardware device generated from a private key of the hardware device, and managing the identification information.
Claims16
An operation method of an electronic device, comprising:
- determining identification information used for authentication of a hardware device using a public key of the hardware device generated from a private key of the hardware device;
- and
- managing the identification information;
- receiving, from the hardware device requiring authentication, identification information of the hardware device;
- checking whether the received identification information is pre-registered identification information, wherein the electronic device checks whether the received identification information corresponds to identification information pre-registered in a valid list;
- when the received identification information does not correspond to identification information pre-registered in the valid list, rejecting authentication of the hardware device and ending operation;
- and
- when the received identification information corresponds to the identification information pre-registered in the valid list, performing, thereafter, public key infrastructure (PKI)-based authentication of the hardware device requiring authentication in response to a case in which the received identification information is the pre-registered identification information using a public key acquired from the received identification information or a public key received from the hardware device requiring authentication,
- wherein, in the performing of the PKI-based authentication, the PKI-based authentication is performed using the acquired public key or the received public key without an authentication certificate issued by a certificate authority (CA) server;
- and
- rejecting authentication of the hardware device in response to the identification information not being the pre-registered identification information.
8 more elements
An electronic device comprising:
- a processor;
- and
- a memory including at least one instruction executable by the processor;
- wherein when the at least one instruction is executed by the processor, the processor:
- determines identification information used for authentication of a hardware device,
- manages the identification information using a public key of the hardware device generated from a private key of the hardware device,
- receive, from the hardware device requiring authentication, identification information of the hardware device;
- checks whether the received identification information is pre-registered identification information, wherein the processor checks whether the received identification information corresponds to identification information pre-registered in a valid list,
- when the received identification information does not correspond to identification information pre-registered in the valid list, rejects authentication of the hardware device and ends operation;
- and
- when the received identification information corresponds to the identification information pre-registered in the valid list, performs, thereafter, public key infrastructure (PKI)-based authentication of the hardware device requiring authentication in response to a case in which the received identification information is the pre-registered identification information using a public key acquired from the received identification information or a public key received from the hardware device requiring authentication, without using an authentication certificate issued by a certificate authority (CA) server, and
- rejects authentication of the hardware device in response to a case in which the received identification information is not the pre-registered identification information.
