![]() Part of the Trustworthy Computing initiative when unveiled in 2002, NGSCB was to be integrated with Windows Vista, then known as "Longhorn." NGSCB relied on hardware designed by the Trusted Computing Group to produce a parallel operation environment hosted by a new hypervisor (referred to as a sort of kernel in documentation) called the "Nexus" that existed alongside Windows and provided new applications with features such as hardware-based process isolation, data encryption based on integrity measurements, authentication of a local or remote machine or software configuration, and encrypted paths for user authentication and graphics output. Microsoft's primary stated objective with NGSCB was to "protect software from software." NGSCB was the result of years of research and development within Microsoft to create a secure computing solution that equaled the security of closed platforms such as set-top boxes while simultaneously preserving the backward compatibility, flexibility, and openness of the Windows operating system. The Next-Generation Secure Computing Base (NGSCB codenamed Palladium and also known as Trusted Windows' ) is a software architecture designed by Microsoft which aimed to provide users of the Windows operating system with better privacy, security, and system integrity. Trusted Mode is the environment introduced by NGSCB and consists of a new software component called the Nexus that provides NGSCB applications-Nexus Computing Agents-with security-related features. ![]() Untrusted Mode consists of traditional applications, Windows, and its components. ![]() NGSCB essentially partitions the operating system into two discrete modes. ![]()
