Even though major hardware makers will support Microsoft's combination of new hardware and software that the software vendor says will boost PC security, Microsoft expects user adoption of its nascent security technology to be slow in the first year after launch, a company executive said Thursday.NEW ORLEANS\u00a0-- Even though major hardware makers will support Microsoft's combination\u00a0of\u00a0new hardware and software that the software vendor\u00a0says will boost PC security, Microsoft\u00a0expects user adoption of its nascent security technology to be slow in the first year after launch, a company executive said Thursday.Called Next-Generation Secure Computing Base (NGSCB) and\u00a0codenamed Palladium, Microsoft demonstrated the technology\u00a0for the first time at WinHEC on Tuesday. The company plans to incorporate the technology in Longhorn, the successor to Windows XP planned for launch in 2005.\u00a0"A small single digit percentage of PCs shipped in the year after (NGSCB) becomes available will support it, ramping up to double digits the year after that," said Peter Biddle, product unit manager at Microsoft's security business unit. "I am not sure if it will ever be in 100% of the systems," he said.Corporate users will likely be first to buy the technology, according to a Microsoft spokesman. Early applications will include secure messaging and other applications especially interesting for corporate PC users, he said.Computer processor maker AMD and graphics chip company Nvidia, two of Microsoft's hardware partners, said Thursday that they plan to have hardware that supports NGSCB ready when Longhorn is introduced. Intel is also expected to have processors ready by that time.AMD thinks NGSCB might be in most PCs by 2008, said AMD Platform Security Architect Geoffrey Strongin."My crystal ball is pretty fuzzy. I don't think ubiquity by 2008 is unreasonable," he said.NGSCB includes a new software component for Windows called a "nexus," and a chip that can perform cryptographic operations called the security support component (SSC). NGSCB also requires changes to a PC's processor and chipset and the graphics card. The combination of hardware and software creates a second operating environment within a PC that is meant to protect the system from malicious code by providing secure connections between applications, peripheral hardware, memory and storage.Microsoft's Biddle expects PC makers to offer systems with and without support for NGSCB, giving PC buyers the choice whether they want it or not."I expect there to be boxes in the store that support (NGSCB) by having the hardware and boxes that do not," Biddle said. Microsoft is not putting any pressure on PC makers to incorporate NGSCB, he added.PCs with NGSCB support will cost more than systems without the technology, Biddle said."It will be a value-added feature that people will be willing to pay more for," Biddle said of NGSCB. Microsoft has said it wants to keep the cost of NGSCB for the PC buyer under $50. Biddle would not give a dollar amount, saying only that $50 "sounds high."Tonya Dezso, a spokeswoman for AMD, said the $50 "sounds reasonable" but added that the higher price would "not come from the processor or other hardware.""We are aiming to keep the cost as low as possible," she said. "Users typically don't want to pay more for anything."Although Microsoft says NGSCB will be a boon for its customers, critics have argued that it will curtail users' ability to control their own PCs and could erode fair-use rights for digital music and movie files. NGSCB could be a Trojan horse for copyright enforcement through its digital rights management capabilities, critics say."Our concerns are whether it can be used to limit the user's control over his PC and prevent interoperability," said Wendy Seltzer, a staff attorney with civil liberties organization the Electronic Frontier Foundation (EFF).
