Patent number: 11954501Abstract: A scheme for restoring a password-protected endpoint device (e.g., a memory device) of a computer system to an operational state from a low power state without requiring user input of a device password. A password received for unlocking the device during a boot process is stored in a secure memory. The password-protected endpoint device subsequently enters the low power state, causing it to lock. During a transition from the low power state to an operational state, it is detected that the password for the endpoint device is stored in the secure memory. The password is fetched from the secure memory and used to unlock the endpoint device, thereby restoring the endpoint device to an operational state.Type: GrantFiled: March 17, 2022Date of Patent: April 9, 2024Assignee: Intel CorporationInventors: Pannerkumar Rajagopal, Bhavana Shankarappa, Kiran Mahesh Eriki

Patent number: 11915008Abstract: In an embodiment, a hardware configuration circuit reads and decodes an encoded life-cycle data and provides the decoded life-cycle data to a hardware circuit. A reset circuit monitors an external reset signal received via a reset terminal and, in response to determining that the external reset signal has a first logic level, executes a reset, a configuration, and a wait phase. The reset circuit waits until the external reset signal has a second logic level. A communication interface is activated during the wait phase and configured to receive a request. A hardware verification circuit generates a life-cycle advancement request signal when the request includes a given reference password and a reset circuit is in the wait phase. A write circuit writes a bit of the encoded life-cycle data stored in a non-volatile memory when the life-cycle advancement request signal is set, advancing the life-cycle to a given predetermined life-cycle stage.Type: GrantFiled: March 11, 2022Date of Patent: February 27, 2024Assignees: ST Microelectronics S.r.l., STMicroelectronics Application GMBHInventors: Roberto Colombo, Nicolas Bernard Rene Grossier, Fabio Enrico Carlo Disegni

Patent number: 11899796Abstract: An initialization geo-locking system includes a chassis housing a location determination subsystem and an initialization management subsystem. During an initialization process that begins in response to receiving initialization power, the initialization management system determines that geo-locking is activated and, in response, causes power to be provided to the location determination subsystem and then subsequently identifies a first current location determined by the location determination subsystem. The initialization management subsystem then determines whether the first current location determined by the location determination subsystem corresponds to an authorized initialization location stored in the initialization management subsystem and, if so, halts the initialization process while, if not, allows the initialization process to complete.Type: GrantFiled: October 19, 2021Date of Patent: February 13, 2024Assignee: Dell Products L.P.Inventors: Wei Liu, Jason Young
