Abstract

Official abstract text for this publication.

One or more techniques and/or systems are provided for securely obtaining memory content after a device malfunction. For example, applications, components, and/or an operating system of a device may maintain information within volatile memory in a secure manner (e.g., using encryption). When the device malfunctions, such information may be useful for diagnosing what caused the malfunction. Accordingly, memory content within volatile memory may be securely retrieved, encrypted, and/or stored before such memory content is flushed/removed from volatile memory. For example, a warm reset is performed to initially reboot the device without removing memory content from volatile memory. The memory content may be retrieved and encrypted to create encrypted memory content that may be stored within nonvolatile memory for later access. After a second reboot, device malfunction information may be obtained by decrypting the encrypted memory content using a private key matching a public key used to encrypt the memory content.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for securely obtaining memory content after a device malfunction, comprising: identifying a device malfunction based upon non-responsiveness of a device; performing a warm reset of the device to initially reboot the device responsive to the identifying, where power is provided to volatile memory of the device during the warm reset to retain memory content within the volatile memory; and responsive to the device being initially rebooted from the…
