Examples disclosed herein relate to systems and methods for assigning an identifier to a node-based system. For example, systems and methods may: discover the plurality of nodes; determine a node of the plurality of nodes to be a controller node: authenticate, at a management component of the controller node, a respective identifier associated with each node of the plurality of nodes; and based on the authentication, assign a complex identifier to a complex comprising the plurality of nodes, wherein the complex identifier comprises the identifier associated with the controller node.

Systems and methods for assigning a cryptographic identity to node-based systems

A process includes accessing by a management controller of a computer platform, a platform certificate that is stored in a secure memory. The platform certificate includes data representing a reference inventory for the computer platform. The platform certificate includes data representing information designated to bind the platform certificate to a security processor. The security processor is accessible by the management controller. The security processor is inaccessible by an operating system of the computer platform. The process includes verifying the platform certificate. Verifying the platform certificate includes validating, by the management controller, a signature of the platform certificate; and validating, by the management controller, the information designated to bind the platform certificate to the security processor. Verifying the platform certificate includes comparing, by the management controller, a second inventory of the computer platform to the reference inventory.

Management controller-based verification of platform certificates

A technique includes detecting a presence of a hardware security module in a computer. The hardware security module performs trusted computing base measurements in response to the boot of the computer. The technique includes detecting an intention to change firmware of the computer and regulating providing a message warning about an impact of the change based on the determination. The regulation includes determining whether an operating system of the computer binds operations to the trusted computing base measurements and allowing communication of the message based on the determination.
