Editor's View -- Exclusive to Electronic Design UPDATE ********************** Your Tax Dollars At Work: NSA Makes Linux More Secure By William Wong, Embedded/Systems/Software Editor The National Security Agency (NSA) has its own brand of Linux called SELinux (Security Enhanced Linux). It is actually an ongoing research project to enhance the security of the Linux kernel to meet the NSA's demanding requirements. The latest release brings this support to the current 2.6 Linux production kernel. Prior to this, SELinux was based on the 2.4 kernel. Although SELinux is a research prototype, Linux distribution companies have indicated they will deploy these enhancements in future products. For example, Red Hat will implement this functionality in its next Red Hat Enterprise Linux release. SELinux is distributed using the open-source GPL (General Public License). SELinux is significant from a couple of standpoints. It is a major improvement over Linux's standard security mechanism. It adds mandatory access controls and access control policies. It also delivers multilevel security support, providing system managers more control when partitioning a system. It is designed to prevent malicious and accidental security breaches. SELinux features are critical in enterprise systems, but they also can be used in embedded systems. To some degree, it is comparable to the software partitioning provided by Arinc 653. This standard includes an application partitioning scheme that is more static than SELinux, but the importance of Arinc 653 in safety-critical and high-reliability environments highlights the need for SELinux type features in networked, embedded applications. Given Linux's importance in the embedded arena, designers would do well to investigate the NSA version's features. Security provisions in most embedded devices are still in their infancy, but with increased connectivity via the Internet and the use of downloaded applications it is imperative that developers provide the kind of partitioned security that SELinux offers. SELinux foregoes the standard Linux root superuser account. Those unfamiliar with SELinux should keep in mind that it is not designed to be distributed for general use like SuSE, Red Hat, or Mandrake. Rather, SELinux focuses on a narrow aspect of security. In fact, the SELinux additions are delivered as source code that will take a Linux expert to install on a standard Linux system. Embedded developers needing this type of support will have to turn to embedded Linux distributions like those from Monta Vista and Timesys. Of course, there is always the option to roll your own. How will this impact other embedded operating systems? In some instances, features similar to this are already available. But for most, this level of partitioning and policy-based security will have to be added. Developer demand will drive enhancements in this area. There remains much to do in the SELinux project. As with most open-source projects, a wide range of developers is working on various aspects of the project. Using the latest version of Linux as a base is key to keeping SELinux relevant, so this latest announcement is very good news. Following the SELinux project has been interesting. There are some who feel that the project competes with commercial interests, but the government supports a wide range of research projects. Many bear fruit that is often far removed from its original intent. The Internet is a key example of this. For more information, go to http://lists.planetee.com/cgi-bin3/DM/y/efAw0Gl4E70EmQ0BGZO0AX .

True Circuits, Inc. offers a family of award-winning clock generator, deskew, low-bandwidth and spread-spectrum PLLs and DDR DLLs that spans nearly all performance points and features typically requested by ASIC and FPGA designers. These high-quality, low-jitter, silicon-proven hard macros are available for immediate delivery in a range of frequencies, multiplication factors and functions in TSMC, UMC and Chartered processes from 0.25 to 0.09 micron. Call (650) 691-2500 or visit http://lists.planetee.com/cgi-bin3/DM/y/efAw0Gl4E70EmQ07EG0Ag . **************************************************************** ********************** 2. Focus On Power ********************** ***Hot-Swap Power Controllers Aim At Telecom, Networking Apps A family of eight highly integrated, hot-swap power controllers specifically targets telecom, networking, and datacom line card applications. The MIC2589 and MIC2595, which come in 14-pin SOIC packages, operate from -19 to -80 V with 100-V surge protection. The devices control an external N-channel MOSFET to provide inrush-current limiting and overcurrent protection with a minimum of other components. They also provide separate "power-is-good" control outputs for multiple dc-dc power converters. These outputs are time-staggered and programmable by an external capacitor. The MIC2589R and MIC2595R versions have an auto-retry feature that will continue to attempt to restart the load in the event of a fault condition. Two versions with reduced feature sets, the MIC2588 and MIC2594, come in space-saving eight-pin SOIC packages. The 14-pin controllers cost $2.38 each in 10,000-unit lots.

News -- From The Editors ********************** ***Quad-Data-Rate SRAMs Deliver Highest Capacity, Bandwidth The highest-bandwidth, highest-density static RAMs are now sampling. The family of 72-Mbit quad-data-rate II (QDR II) and double-data-rate II (DDR II) SRAMs deliver up to 50% more system-level bandwidth and accelerate read/write capabilities in a variety of data-intensive applications. Storage capacity is more than twice that of previous QDR II/DDR II SRAMs. The memories come in speed grades from 167 to 200 MHz (eventually 250 MHz). Versions will be available in 4-Mword by 18-bit, 8-Mword by 9-bit, and 2-Mword by 36-bit organizations. The 4-M by 18 and 8-M by 9 versions are available with a burst of 2 words interface, the 2-M by 36-bit version with a burst of 4 capability. The DDR II version is available with a burst of 2 and separate I/O options. The CY7C15XXV18 family supports the LA-1 bus interface, which is used by a wide array of network processors, and the DDR-II SRAM interface, which is used by most of the remaining network processors. Housed in 165-contact FBGAs that measure 15 by 17 mm, the memories consume between 1.5 and 2 W when powered by a 1.8-V supply, depending on speed grade and I/O option. In lots of 10,000, prices start at $145 apiece for the CY7C1512V18 4-Mword by 18-bit device. Cypress Semiconductor Corp. ==> http://lists.planetee.com/cgi-bin3/DM/y/efAw0Gl4E70EmQ0pcG0A8 ***Name Change Helps Define Change In Product Direction In an effort to redefine its ASIC product capabilities and implementation services, Chip Express has renamed itself ChipX to indicate its ability to provide ASIC design on a family of structured ASIC platforms. The company has moved away from its initial fast-turnaround ASIC service using laser configuration and now is focused on supporting companies implementing designs with families of structured ASICs. The latest such devices are its CX5000 family of 180-nm based chips, which offer from 44k to 1.8M useable gates and up to 2.6 Mbits of memory. To date, the company has implemented 34 structured ASIC designs for customers, and many more designs are in the pipeline. ChipX ==> http://lists.planetee.com/cgi-bin3/DM/y/efAw0Gl4E70EmQ0BGZQ0AZ ***Robots Lose, But Technology Wins It was a bold idea. Offer a million dollars to the first team to build an autonomous vehicle that could race from California to Las Vegas in less than 10 hours. Unfortunately, no one claimed the prize. Twenty-five teams entered DARPA's Grand Challenge, which took place on March 13. However, only 15 actually qualified to tackle the 142-mile course from Barstow, Calif., to Primm, Nevada. None came close to finishing the course. Two withdrew prior to the start of the race. Three didn't even make it out of the starting area. The others had varying degrees of success. The "Sandstorm" from the Red Team, a group of students from Carnegie Melon, got the farthest. It crossed 7.4 miles before veering off course and getting stuck on a berm. While nobody took the prize, the event was "a most important first step in a long journey," said Anthony Tether, director of DARPA. "We learned a tremendous amount today about autonomous ground vehicle technology." This truly is significant, as the Department of Defense aims to convert a third of all ground combat vehicles to unmanned vehicles by 2015. DARPA expects to hold the Grand Challenge again. ********************** 4.
