Abstract: An electronic system and a security authority delegation method thereof are provided. The electronic system includes a first host device, a second host device, a first security device, and a second security device. The first security device is connected to the first host device. The second security device is connected to the second host device and the first security device. The first security device performs an attestation process on the second security device. If the second security device passes the attestation process, the first security device enables the second security device to verify executable images of the second host device. If the second security device does not pass the attestation process, the first security device disables a function of the second security device, and the function includes verifying the executable image of the second host device.

Abstract: A baseboard management controller (BMC) and an operation method thereof are provided. The BMC includes a path switching circuit, a host interface circuit, a universal serial bus (USB) hub controller, a USB physical layer circuit, and a control circuit. The host interface circuit is adapted to be electrically connected to a host circuit outside the BMC. The USB physical layer circuit is adapted to be electrically connected to an external USB host or an external USB device outside the BMC. The control circuit controls the path switching circuit to selectively couple the host interface circuit to the USB hub controller, selectively couple the USB hub controller to the USB physical layer circuit, or selectively couple the host interface circuit to the USB physical layer circuit.

Abstract: An event reporting method, a security management circuit, and a management system are provided. The management system includes first, second, and third security management circuits. The first security management circuit and the second security management are respectively located at a first layer and a second layer of a hierarchy structure. The third security management circuit is located at another layer of the hierarchy structure different from the first layer and the second layer. The first, second, and third security management circuits are respectively configured to determine an event occurring on a host connected to these security management circuits. A dedicated line is communicatively connected between the first and third security management circuits. According to a type of the event determined by the third security management circuit, the third security management circuit reports the event through the dedicated line. Accordingly, a reporting efficiency and system security are improved.
