Secure Boot Encryption with Linux: Implementation for Embedded Developers (Apress Pocket Guides)

Secure Boot Encryption with Linux serves as a quick guide to building and maintaining a secure, embedded Linux system by establishing a verifiable Chain-of-Trust from the moment power is applied until the first user space application takes control.It meticulously breaks down what the Secure Boot implementation is, and critically, what it is not by providing the technical knowledge necessary to guard against sophisticated bootkits and unauthorized code execution. We begin by dissecting the Linux Cryptographic Subsystem and the core mechanism for secret protection: the Linux Key-Management Facility (Keyring).It provides an in-depth, practical guide to implementing Trusted Keys and Encrypted Keys, detailing how these secrets are secured by tying them to specialized hardware like the Trusted Platform Module (TPM).This unique focus ensures that critical encryption and signing keys are never exposed to user spaces, neutralizing the impact of successful root-level exploits.Next, we explore th
