Seamless and secured device startup after device part replacement

A non-transitory machine-readable medium having instructions stored therein, which when executed by a processor, cause the processor to perform operations for managing a boot up process of a data processing system, the operations comprising:

• obtaining, by a management controller the data processing system, a device key request from one or more boot up components of the data processing system, the device key request comprising data processing system component information;
• parsing, by the management controller, the data processing system component information to obtain a first device identifier (ID);
• determining, by the management controller, that the first device ID is different from a second device ID associated with an existing device key stored in an active device key storage of a device key repository;
• replacing the existing device key in the active device key storage with a new device key stored in a device key repository of the management controller, the new device key having a third device ID that matches the first device ID;
• providing, by the management controller, the new device key to the one or more boot up components as requested in the device key request;
• and
• using, by the one or more boot up components, the new device key to complete a boot up of the data processing system.

A data processing system comprising:

• a management controller;
• and
• one or more boot up components, wherein data processing system stores instructions that causes the data processing system to perform operations for managing a boot up process of a data processing system, the operations comprising:
• obtaining, by the management controller the data processing system, a device key request from the one or more boot up components of the data processing system, the device key request comprising data processing system component information;
• parsing, by the management controller, the data processing system component information to obtain a first device identifier (ID);
• determining, by the management controller, that the first device ID is different from a second device ID associated with an existing device key stored in an active device key storage of a device key repository;
• replacing the existing device key in the active device key storage with a new device key stored in a device key repository of the management controller, the new device key having a third device ID that matches the first device ID;
• providing, by the management controller, the new device key to the one or more boot up components as requested in the device key request;
• and
• using, by the one or more boot up components, the new device key to complete a boot up of the data processing system.
