Abstract
In some examples, a system receives, as part of a process to reset a target device, a one-time value (OTV) generated by the target device. The system sends the OTV from the system to an authentication server. The system receives, from the authentication server, a signature derived from the OTV. The system provides the signature to a controller in the target device that triggers the reset of the target device.
Claims20
A non-transitory machine-readable storage medium comprising instructions that upon execution cause a system to:
- receive, at the system as part of a process to reset a target device, a one-time value generated by the target device;
- send the one-time value from the system to an authentication server;
- receive, at the system from the authentication server, a signature derived from the one-time value;
- and
- provide the signature to a controller in the target device that triggers the reset of the target device.
A target device comprising:
- a management controller to:
- generate a one-time value for a process to reset the target device;
- send the one-time value from the target device to a system;
- receive, at the target device from the system, a signature derived from the one-time value by an authentication server;
- verify the signature;
- and
- based on verifying the signature, trigger the reset of the target device.
A method comprising:
- receiving, at a system comprising a hardware processor as part of a process to reset a target device, a one-time value generated by the target device, the one-time value based on a random number produced at the target device;
- sending the one-time value from the system to an authentication server;
- receiving, at the system from the authentication server, certificate information and a signature derived from the one-time value, the certificate information comprising a device certificate of the target device;
- and
- sending the certificate information and the signature through a management interface of a controller in the target device to trigger the reset of the target device based on a verification of the certificate information and a verification of the signature.
