Trusted computing using AMD Pacifica and Presidio secure virtual machine technology

The success of the computer industry over the last 20 years is also the source of the greatest challenge to the industry. The combination of wide, near-ubiquitous deployment of platforms based on the x86 architecture, operating systems that allow users to both develop and execute arbitrary software, and finally the interconnection of large numbers of such systems via the Internet, has led toa ‘‘Perfect Storm’’ofcomputer securityproblems. The consequences of computer security failures are increasingly severe. Most governments and businesses now rely upon computers for day-to-day tasks as well as for mission-critical applications. Individuals regularly depend on personal computers for access to information, entertainment, and personal financialmanagement. Computers also control elements of critical infrastructure where the consequences of failure extend into the physical world. The dynamics of the free market have led to a range of commercial responses to evolving computer security problems. Software tools targeted at addressing individual threats emerged and have met substantial market success. Followon products that address more threats are now in wide distribution. Operating system vendors have also made significant investments in training, tools

The role of trusted computing in internet scale DRM

The XRI Data Interchange (XDI) protocols and schemas provide a foundation for internet scale exchange of data between parties based on mutually agreed upon policies. Local enforcement of the policy and the preservation of the persistent binding between the data and policy imply a local policy enforcement system. This talk explores the relationship between trusted computing, remote attestation and local policy enforcement capabilities in an Internet scale environment.
