The Fundamentals of Secure Boot and Secure Download: How to Protect Firmware and Data within Embedded Devices

筆者: Scott Jones, Christophe Tremlet, and Michael Jackson

要約: To ensure that the target embedded device runs only authorized firmware or uses only authorized configuration data, we need to provide a way to verify both authenticity and integrity of the information. This means making sure that the data is trusted and not subsequently modified. Utilizing cryptographic digital signature, like putting a seal or a manual signature at the bottom of a letter, enables this integrity.
