摘要： A system includes long-term storage (e.g., flash memory) for storing sensitive data and critical components of a consumer electronic (CE) device such as an operating system (OS) kernel, private cryptographic key values, security applications, and firmware configurations, for example. Security hardware/software designates and restricts access to secured portions of long-term storage that contain the critical components. Requests for access to these secured portions are addressed by the security hardware/software, which authenticates a cryptographic authorization code received with the request. Read-write access to the secured portions is allowed for download and installation of, for example, a software or firmware upgrade if the cryptographic authorization code is authenticated.
