NGSCB

(Next Generation Secure Computing Base) A Windows security platform from Microsoft introduced in 2002, and originally called "Palladium." First used in Windows Vista in 2007, applications that support NGSCB can be isolated within the computer; their data can be sealed and made unavailable to other applications, and data can be digitally signed to ensure they were created by a trusted application. Viruses may still enter and reside within the computer, but NGSCB-aware applications are far less vulnerable to their damage.

Software and Hardware
NGSCB employs a "nexus" software module that runs alongside Windows that applications communicate with, and regular applications and nexus-aware applications run together in the same PC. NGSCB requires a Security Support Component (SSC) chip in the motherboard, called the Trusted Platform Module (see TPM) by the Trusted Computing Group (see TCG). The SSC/TPM includes RSA and AES private keys that never leave the chip, and it provides encryption/decryption and digital signature generation.

User Authentication and Digital Rights
NGSCB does not provide user authentication; it provides machine and application authentication. Smart cards and other user authentication methods are still required. NGSCB also does not provide digital rights management (DRM); however, rights management systems can call upon the nexus module for more security.

From the Goddess Athena
The original Palladium name came from ancient Troy, where the Palladium was a sacred, stone statue of the goddess Athena, said to be the protector of the city. See TCPA.

Microsoft added: "We are honored that NGSCB has been recognized for Balancing Innovation and Reality by the executive advisory committee of Digital ID World," said John Manferdelli, general manager Microsoft Windows Trusted Platform and Infrastructures.
NGSCB is scheduled to be included as part of the next major release of Windows, code-named "Longhorn," for use on computers with the required hardware support.
NGSCB has made consumer activists and civil libertarians extremely uncomfortable in terms of the power to control digital content this potentially grants Microsoft through its ownership of the Windows operating system and many popular applications.
