Microsoft announced its forward direction for hardware-based security. The Register's article is here. Snippets:
Secure Startup will combine full-volume encryption, integrity checks and the hardware-based Trusted Platform Module (TPM) to detect malicious changes to the computer and protect the user's data if the laptop is stolen, the software giant stated at its annual Windows Hardware Engineering Conference (WinHEC). The Trusted Platform Module is a standards-based hardware design created by the Trusted Computing Group, of which Microsoft is a member.
While the technologies, once known as Palladium and now called the next-generation secure computing base (NGSCB), will help companies and consumers lock down their computers and networks, concerns remain that the hardware security measures could also be used to lock-in consumers to a single platform and restrict fair uses of content.
With homegrown integrity and security features being added by a variety of devices by companies aiming to lock out competition using the Digital Millennium Copyright Act (DMCA), the specter of another hardware-based security feature worries some information-system experts.
