Publication number: 20250141699Abstract: Methods and systems for authenticating a user device to an application device are disclosed. The user device may request access to a (computer-implemented) service provided by the application device. Access to the service may include access to sensitive data; therefore, to prevent unauthorized access to the sensitive data, the user device may be authenticated to the application device before the service is provided. To do so, the application device may perform a first factor authentication using in-band hardware resources of the user device; however, the in-band hardware resources may be vulnerable to attacks by malicious parties. Thus, in addition, a second factor authentication of the user device may be performed out-of-band (e.g., using a management controller of the user device) in order to bypass potentially compromised in-band hardware resources. The additional out-of-band authentication may reduce the likelihood of the malicious parties gaining access to the sensitive data via spoofing attacks.Type: ApplicationFiled: October 31, 2023Publication date: May 1, 2025Inventors: MOHIT ARORA, ABEYE TESHOME, RICHARD M.

Publication number: 20250141856Abstract: Methods and systems for registering a management controller of a data processing system with a new message broker are disclosed. The management controller may be previously registered with an existing message broker. A server may provide a certificate for the data processing system to the new message broker and the server may notify the management controller that the registration process has been initiated. In response, hardware resources of the management controller may provide a registration request to the new message broker. The new message broker may provide a challenge to the management controller via an out of band communication channel and the management controller may provide a challenge response also via the out of band communication channel. Doing so may complete the registration of the management controller with the new message broker. The server may then un-enroll the management controller from the existing message broker.Type: ApplicationFiled: October 31, 2023Publication date: May 1, 2025Inventors: VINODKUMAR VASUDEV OTTAR, ABEYE TESHOME, RICHARD M.

Publication number: 20250141674Abstract: Methods and systems for registering a management controller of a data processing system with a server are disclosed. To register a management controller, an identifier for the management controller may be cryptographically signed using a private key of a public private key pair kept secret by a trusted platform module (TPM). The signed identifier may be provided to the server and the sever may utilize a public key of the public private key pair to verify the signed identifier was signed by a trusted entity. If the signed identifier is verified by the server, the server may register the management controller as associated with the data processing system and as a trusted entity to manage operation of hardware resources of the data processing system. The management controller may subsequently utilize an out of band communication channel to interact with the server to manage the operation of the data processing system.Type: ApplicationFiled: October 31, 2023Publication date: May 1, 2025Inventors: RICHARD M.

Publication number: 20250141661Abstract: Methods and systems for registering a management controller of a data processing system with a server and an orchestrator are disclosed. To do so, a key pair may be generated by the management controller and a private key of the key pair may be kept secret by the management controller. Previously established trust between a trusted platform module of the data processing system and a manufacturer of the data processing system may be leveraged to register the management controller with the server. Hardware resources of the data processing system may register a public key of the key pair with the server and may request registration of the management controller with the orchestrator. The management controller may obtain a challenge from an internet of things hub associated with the orchestrator and may respond to the challenge, via an out of band communication channel, to complete the registration of the management controller.Type: ApplicationFiled: October 31, 2023Publication date: May 1, 2025Inventors: ABEYE TESHOME, RICHARD M.
