Abstract
A switch component secure upgrade system includes a dual-ported switch component, a central processing system that is connected to the switch component via the components read-only port, and a management controller system that is connected to the switch component via the components read-write port. The management controller system receives a component upgrade request that is encrypted with a management controller public key, decrypts the component upgrade request using a management controller private key, and validates the component upgrade request, which is signed with a release management private key, using a release management public key. In response to validating the component upgrade request, the management controller system validates a component upgrade payload that is included in the component upgrade request and, in response, upgrades the switch component via the read-write port using the component upgrade payload.
