Since our last virtual discussion (June 2008), malware attacks continue to rise, and more so, attacks have continued to become stealthy and targeted. We have completed a key milestone for our software protection research last month; we created a research prototype of a hardware-assisted application protection capability called “Processor-Measured Application Protection Service (P-MAPS)”. The goal of this work has been to significantly reduce the Trusted Computing Base (TCB) from a full Operating System to a substantially smaller P-MAPS layer to improve the runtime security of critical applications running within the OS. The main contributions of our work are the on-demand trusted instantiation of P-MAPS and the use of P-MAPS to protect applications without interrupting the natural operation of the application or the Operating System. With P-MAPS enabled on a platform, day-0 attacks and attempts by unknown malware to attack critical applications can be mitigated.

At Fall IDF 2008, Intel presented solutions toward realizing a vision that can accelerate secure Internet transactions by orders of magnitude. Our vision was of a world where the internet is entirely secure and attackers have no place to hide. A major step toward realizing this vision of world-wide security is making sure that all the traffic exchanged between servers and clients is encrypted. This is very difficult technical challenge since networking speeds are excessively high (10-100 Gbps), whereas cryptographic algorithms consume millions of processor cycles to execute. Since IDF, we have also worked on designing new cryptographic algorithms that can potentially offer new security/performance tradeoffs and be essential components of future computing platforms and networks. In this blog we summarize our past as well as recent accomplishments.

Real-time services are envisioned to be an essential component of next generation mobile broadband networks (4G), and like 2G and 3G, voice is still expected to be the most desirable service over these networks. However, mobile-broadband networks, based on IP technologies, are well-known for high packet-data efficiency, but not for voice (VoIP) efficiency. A key requirement for IEEE 802.16m, the next-generation WiMAX standard, currently under definition, is support of a large number of VoIP users. Hence, efficient support of VoIP over next-generation WiMAX is needed.
