MS, AES 암호 규격의 방어벽에 처음으로 균열 생긴 것
미국 마이크로소프트와 벨기에 있는 루벤·카톨릭대학의 연구자들이 널리 사용되고 있는 AES암호 알고리즘을 공격하는 방법을 발견했다고 외신이 보도했다.
 
루벤·카톨릭대학의 보고(Biclique Cryptanalysis of the Full AES )에 의하면 그들이 고안한 공격 수법은 종래 고려되어 왔던 속도의 3배에서 5배 속도로 AES 비밀 키를 복구(recovery)하는 것이 가능하다.
 
연구자들은 이 공격은 본질적으로 복잡한 것으로 기존 기술을 이용해서 간단하게 공격되지는 않는다고 주의를 촉구하고 있다. 실제로 연구자들이 채용한 수법에 의하면 AES 암호 알고리즘을 해독하는 데에는 수 십억 년에 해당하는 컴퓨터 처리 시간이 필요한 것 같다.
 
그러나 오랜 기간에 걸친 그들의 암호 해독 프로젝트가 내 놓은 성과는 지금까지 해독 불능이었던 AES 암호 규격의 방어벽에 처음으로 구멍이 열린 것이라고 말해도 좋을 것이다.
 
금융거래의 안전화라는 극히 중요한 처리에 적용되는 암호 규격을 평가하는 경우, 시큐리티 전문가는 암호화 알고리즘이 극히 악의적인 공격에도 견디어내는 능력을 갖고 있는 지를 판단한다.
 
지금 이 순간은 안전한 암호화 방법이라고 생각되는 기술일지라도 가까운 미래에 등장하게 될 고속 컴퓨터나 수치 연산의 새로운 기술이 출현하는 경우에는, 쉽게 그 벽이 무너질지도 모르기 때문이다.
 
이번 조사에 의해서 “AES 안전성의 한계도 지속적으로 떨어지고 있다는 사실을 알게 되었다”고 시큐리티 전문가인 Bruce Schneier는 자신의 블로그에 남겼다.
 
또한 Schneier는 “공격 수법은 항상 진화하고 있다. 이것은 결코 퇴화하는 일은 없다”라는 미국 NSA의 전문가의 말도 블로그에 인용하고 있다.
(www.schneier.com/blog/archives/2011/08/new_attack_on_a_1.html)
 
실행하기에는 대단한 노력이 필요하지만 연구자들이 확립한 공격 방법은 다양한 버전의 AES에 대해서도 유효하다.
 
Microsoft Research의 Dmitry Khovratovich, 루벤·카톨릭대학의 연구자인 Andrey Bogdanov, 파리에 있는 Ecole Normale Superieure (ENS)의 Christian Rechberger 등 3명이 이번 프로젝트를 완수했다.
 
Bogdanov와 Rechberger는 Microsoft Research와 공동으로 프로젝트에 전념하기 위하여 대학을 휴학한 것 같다. 루벤·카톨릭대학에 의하면, AES를 제안하였던 Joan Daemen과 Vincent Rijmen도 이들 공격의 유효성을 인식하고 있다고 말했다.

Microsoft Corp.'s next version of its Office desktop programs will reach consumers next year, though not likely in conjunction with the Windows 7 operating system.

Microsoft ( MSFT - news - people ) is set to announce Wednesday that Office 2010 will be finished and ready to send to manufacturers in the first half of next year.

From there, it can take six weeks to four months or more for the programs to reach PC users, said Chris Capossela, a senior vice president in the Microsoft group that makes Office. The timing will differ for big businesses and individual consumers, and for people who buy packaged software versus those who download it.

Some industry watchers had expected a new version of Office this year, but Microsoft Chief Executive Steve Ballmer extinguished that rumor at a meeting with analysts in February.

Capossela declined to be more specific about a launch date. Windows 7, the successor to Windows Vista, is scheduled to reach consumers by the end of January 2010.


Office 2010 - previously known by the code name "Office 14" - will include slimmed-down versions of Word, Excel, PowerPoint and OneNote that let people create and edit documents in a Web browser. Consumers will have access to a free, ad-supported version, and Capossela said the company is still hammering out what to charge businesses that want a version without ads.

Microsoft plans to let hundreds of thousands of people test a technical preview of the new Office portfolio starting in the third quarter of 2009, Capossela said. The company did not say whether average PC users will have a chance to test a more polished beta version.

Microsoft also said a new version of its Exchange e-mail server will be available for purchase in the second half of 2009. When paired with the next version of Microsoft's Outlook e-mail program, Exchange 2010 aims to prevent e-mail faux pas and would warn people against trying to "reply all" to a huge distribution list. Microsoft said it can also be tweaked to stop people from sending e-mail outside the organization, helping businesses cut down on unnecessary e-mail and prevent leaks.

Parties settle dispute after more than a year

* Microsoft (nasdaq: MSFT - news - people ) says TomTom to make payments

* Financial details of settlement not disclosed

(Adds background on dispute, share prices)

SEATTLE (Reuters) - Microsoft Corp and Dutch navigation device maker TomTom NV said Monday they had reached a settlement after more than a year of squabbling over software patents.

In the last few weeks, both companies had sued the other, claiming patent infringement.

Under the terms of a five-year agreement, Microsoft said TomTom will pay Microsoft for use of the eight car navigation and file management system patents in the case Microsoft brought against TomTom, while Microsoft will be able to use the four patents included in the TomTom countersuit without any payment to TomTom.

TomTom confirmed there was a settlement but declined further comment.

Specific financial terms of the agreement were not disclosed.

The world's largest software company in February sued in federal court in its home state of Washington and petitioned the U.S. International Trade Commission claiming TomTom -- which makes portable navigation devices for cars and mapping software for handheld computers -- breached eight of its patents.

Microsoft said the patents involved in the case related to innovations in car navigation technology and other computing functionality that Microsoft has licensed to other companies, such as TomTom's rival Garmin Ltd. (nasdaq: GRMN - news - people )

TomTom countersued in the U.S. District Court for the eastern district of Virginia, earlier this month, claiming Microsoft violated a number of its patents.

Microsoft shares slightly pared losses after the announcement, down 3.9 percent at $17.43 in a broad market decline. Ahead of the settlement announcement, TomTom shares closed at 3.413 euros in Amsterdam, down 7.2 percent. (Reporting by Bill Rigby; Editing by Tim Dobbyn)

Microsoft Corp. plans a central market to sell programs for cell phones running the Windows Mobile system. It hews closely to the setup of Apple Inc.'s App Store for iPhones, with one notable exception - Microsoft promises to communicate more openly with outside software developers.

Apple (nasdaq: AAPL - news - people ) started what has become an "app store" arms race a year ago, giving software programmers a single place to market applications to enthusiastic iPhone owners. The overnight success of the model - Apple claimed 10 million downloads in a weekend - was followed by Google Inc. (nasdaq: GOOG - news - people )'s similar one-stop shop for its Android phone system.

Microsoft (nasdaq: MSFT - news - people ), Nokia Corp. (nyse: NOK - news - people ) and Research in Motion Ltd. (nasdaq: RIMM - news - people ) have announced similar intentions recently.

Redmond, Wash.-based Microsoft was set to reveal more details of its own effort Wednesday. Like Apple in its App Store, Microsoft plans to take 30 percent of sales from the Windows Marketplace for Mobile. Software programmers who want to sell applications through the Microsoft store must pay $99 a year for the privilege, the same fee Apple charges. Programmers can set their own prices, starting at 99 cents, or give their programs away, as long as they pass Microsoft's muster.

Apple's App Store gave programmers a way to profit from the iPhone's mounting buzz. It also drew criticism from some who said the company is too secretive about the process. Developers have complained that it takes weeks or more for Apple to approve or reject their submissions and that reasons for rejections are murky or inconsistent.

Apple declined to comment.

Microsoft vows it will be more forthright and responsive than Apple has been.

A few weeks after launching the first wide-scale layoffs in its history, Microsoft Corp. admits it screwed up a key part of the plan.

The company is asking some laid-off employees for a portion of their severance back, saying an administrative glitch caused the software maker to pay them too much.

Lou Gellos, a Microsoft (nasdaq: MSFT - news - people ) spokesman, would not say how many of the 1,400 workers let go in January were overpaid, or by how much. Microsoft has said severance would be calculated by length of service and position in the company.

The Redmond, Wash.-based software maker is asking former employees for reimbursement, by check or money order, within two weeks, according to a redacted letter posted by the technology blog TechCrunch. Gellos confirmed the letter's authenticity.

With the recession biting into sales of Microsoft's core Office and Windows software, Microsoft said in January it would let up to 5,000 of its 94,000 employees go, the only mass layoff in its 34-year history.

Shares of Microsoft sank 54 cents, or 3 percent, to $17.46 in afternoon trading amid a broader sell-off Monday.

Microsoft and Sony will talk up their console-centric home entertainment plans in back-to-back keynotes at CES.

Ever since the debut of the Atari 2600 in 1977, if a console vendor's gaming instincts were not clean and strong, consumers would hesitate at the moment of truth. The consoles would not sell. And console makers died.

It's now clear that lesson was lost on Microsoft (nasdaq: MSFT - news - people ) and Sony (nyse: SNE - news - people ). Expect Microsoft Chief Executive Steve Ballmer to talk a lot about the Xbox 360 at the Consumer Electronics Show in Las Vegas on Wednesday, and Sony Chief Howard Stringer to highlight the role of the PlayStation in that battle as part of his CES keynote the next day.

For now, at least, the two consoles lag far behind Nintendo's (other-otc: NTDOY.PK - news - people ) Wii, in large part because of the Wii's low price and focus on family-friendly games. As Microsoft and Sony tried to transform their gaming consoles into set-top supercomputers able to juggle any kind of home entertainment, tiny Nintendo snuck by to grab the console crown from Sony's Playstation 2.

So what went wrong? An insider-y new book, The Race for the New Game Machine, due out later this year, and reviewed by the Wall Street Journal, sheds some light on what happened.

The account, written by a pair of IBM (nyse: IBM - news - people ) engineers, documents the effort by Sony, Toshiba (other-otc: TOSBF.PK - news - people ) and IBM to create a new processor for the PlayStation 3. It now looks like Sony got taken, with Microsoft ordering a processor from IBM that took advantage of much of the work done by Sony and its partners to create the cell.

The result: The feature-laden PlayStation 3 now starts at $379, Microsoft's Xbox 360 starts at $199 and the Wii, after starting out as the cheapest of the trio, now goes for $249. "Sony almost crippled themselves pursuing Microsoft's vision because they over-engineered it," says Wedbush Morgan analyst Michael Pachter. "They were really thinking about a home media center."

All that engineering, however, has yet to pay off. According to figures released by Nielsen Media Research, Sony's old PlayStation 2 is still the most used gaming console, accounting for 31.7% of the time spent playing. The Xbox 360 was second, with 17.2%, then the Wii with 13.4%. The original Xbox still gets 9.7% play time, but Sony's latest console, Playstation 3, racked up just 7.3% of total console usage time.

How To Make Money Online

Business 2008. 12. 22. 06:39

Suleman Ali needed a change. So, in mid-2007, he left his programming gig at Microsoft to start a company--any company. On a whim, he wrote an application for Facebook, the social networking Web site, called Superlatives, which lets visitors rate their friends as the smartest, best-looking and such. It immediately caught fire.

"I basically started building it out of boredom, and people started noticing it three days after I launched it," says Ali. So did interested suitors: Nine months later, the 26-year-old sold his hobby-cum-enterprise, called Esgut, to Palo Alto, Calif.-based Social Gaming Network for "several million dollars" (he's not allowed to share the exact purchase price).


For all the troubles in the economy, the Internet continues to be a hotbed of innovation, entrepreneurship and, as development costs continue to decrease, stiff competition. Some of the most lucrative ideas have yet to hit the drawing boards. "I could almost make the case that the idea you think is really stupid is [the one that will] succeed," says Guy Kawasaki, partner at Garage Ventures.

Ali financed Esgut, with an eight-employee roster, by selling advertising that runs alongside its applications. By the time he sold the business, the company's six apps had attracted some 14 million unique users. Now Ali is ready for round two. Despite the downturn, the young entrepreneur says he's in "brainstorming" mode with a high school friend and MIT graduate.

My name is Asher, and I'm a recovering iPod junkie. Last fall I kicked my three-year habit when the earphone jack on my black, 30-gigabyte iPod Classic came loose, leaving me with fuzzy sound on the right side. I didn't have time to get it fixed--and funny enough, after a few days I didn't much miss it.

Even so, when an editor asked me to compare Microsoft's Zune to Apple's iPod Touch, I was sure my affinity for any and all hardware incubated in Cupertino, Calif., (I've been a Mac user since age 5) would destroy my objectivity.


Having given my disclosures, here's my verdict: The Zune is pretty nifty. The Touch, however, is a superfluous addition to Apple's (nasdaq: AAPL - news - people ) iPod roster.

Cheaper than the highest-gigabyte Touches and about the same price as a Classic, the Zune has a bigger screen than the latter and graphics quality as strong as the former. The 120 GB Zune goes for $250, just $21 more than an 8 GB Touch. The 32 GB Touch goes for a savings-busting $399.

And what do you get with a Touch? As anyone who's ever used one knows, it's an iPhone...without the phone. The Touch has Web applications in case you're in a wi-fi area, but who wants to go hunting for a hotspot when you're out and about?

Most people who buy the Touch are hankering for its iPhone-sized screen, which provides a better video-watching experience than any other iPod. But the storage room just isn't enough: Even if you've got the 32 GB, good luck squeezing in all your favorite music, photos and movies.

Ballmer to talk Windows 7 at CES

Ballmer to talk
Windows 7 at CES

December 10, 2008 12:49 PM PST

In his CES keynote, Microsoft's CEO will focus on Vista's successor, plus pushing Windows on Web and phone. But: No ZunePhone.

Microsoft will have a bunch of stuff to show at the Consumer Electronics Show in January, but a rumored ZunePhone won't be one of them, according to sources familiar with the company's plans.

Instead, much of CEO Steve Ballmer's focus will be on talking about Windows 7 from a consumer perspective. Microsoft is pushing to have Windows 7 done in time for the holiday 2009 shopping season, so that means this CES is Ballmer's best stage to tout its benefits.

While the desktop operating system will be front and center, sources say to expect Ballmer to talk about how Windows is moving beyond the PC and into a world of PC, Web, and phone, a refrain we also heard a lot from Ray Ozzie at November's Professional Developers Conference, where the world also got its first good look at Windows 7.

On the phone front, Microsoft may not have a ZunePhone, but it is going ahead with several other strategies--pushing phone makers to develop phones based on Windows Mobile, developing Windows Live services for phones running a variety of operating systems as well as a number of new "premium mobile services" based on its Danger acquisition.

The company has also talked about extending its Zune service beyond the company's own dedicated player and mentioned the phone as a logical place to access the service. We may hear more about timing of this at CES, I'm told. In an October interview with CIO UK, Ballmer mentioned the possibility of accessing the Zune service on Windows Mobile phones.

The Xbox will certainly get its due as well during Ballmer's keynote speech and, as is typically the case, expect Microsoft to announce some new partnerships at the show. A funny video and celebrity guest are usually safe bets as well.

So that's what I've heard, but if tipsters know any more, I'm all ears.
