17% Smaller DES S-box Circuits Found
Posted: July 1st, 2011, 8:35pm CEST by Soulskill
Tags: encryption
solardiz writes "DES is still in use, brute-force key search remains the most effective attack on it, and it is an attractive building block for certain applications (the key size may be increased e.g. with 3DES). Openwall researchers, with funding from Rapid7, came up with 17% shorter Boolean expressions representing the DES S-boxes. Openwall's John the Ripper 1.7.8 tests over 20 million combinations against DES-based crypt(3) per second on a Core i7-2600K 3.4 GHz, which roughly corresponds to a DES encryption speed of 33 Gbps." -
How Japan's Data Centers Survived the Earthquake
Posted: July 1st, 2011, 7:37pm CEST by Soulskill
Tags: japan
jfruhlinger writes "A lot of Japan's infrastructure was knocked offline by this year's massive earthquake and tsunami, but its data centers by and large stayed running. How'd they pull it off? Good architecture and good planning, for the most part. But the data centers still face challenges in post-quake Japan, not least a new law mandating reductions in power use."Read more of this story at Slashdot.

Time To Close the Security Theater
Posted: July 1st, 2011, 4:53pm CEST by Soulskill
Tags: security
An anonymous reader writes "An editorial at Forbes calls for the dismantling of the TSA, pointing to recent headlines as the latest examples of 'security theater' at its worst. From the article: 'The problem isn't that the TSA is harassing the wrong people. The problem is that the TSA is harassing anyone. The TSA is encroaching on fundamental liberties and providing no discernable benefit. ... Naturally, the TSA responds to incidents like these by saying that the agents are highly trained and that they have followed proper procedure. This indicates a signal failing for the agency: if "doing it by the book" involves touching people in ways that would be considered sexual assault in virtually any other context or telling a 90-year old breast cancer survivor to remove her bra lest it contain explosives (as happened to a friend's grandmother), then the book needs to be shredded and rewritten. Better yet, it needs to be replaced with a competitive market for air travel in which the airports, the airways, and the airliners are in private hands. Some might object that private firms will have incentives to cut corners on safety. It is a legitimate concern, but competitive mechanisms tend to weed this out.'"Read more of this story at Slashdot.

The Most Dangerous Programming Mistakes
Posted: July 1st, 2011, 3:31pm CEST by Soulskill
Tags: programming
snydeq writes "Fatal Exception's Neil McAllister discusses the most dangerous programming mistakes, and what can be done to avoid them. 'Even more than input validation errors, this year's list is rife with application security blunders of all kinds. Some of them sound fairly esoteric, such as "inclusion of functionality from untrusted control sphere." But of all such errors, the highest-ranking one on the list is "missing authentication for critical function" — in other words, the attacker was able to gain access because there was no lock on the door to begin with,' McAllister writes. 'With the pace of Internet attacks accelerating, now is not the time to cut QA staff or skimp on testing and code review.'"Read more of this story at Slashdot.

40GB of Data That Costs the Same As a House
Posted: July 1st, 2011, 10:56am CEST by timothy
Tags: internet
Barence writes "PC Pro has an infographic that reveals the extortionate cost of roaming data. They compared the cost of data typically bundled with a fixed-line broadband package (40GB) costing £15, with the cost of buying that data on various mobile tariffs. Buying 40GB of data on a domestic mobile internet tariff from Orange would cost the same as an iMac; buying the same quantity of data on O2's non-Europe roaming tariff would cost £240,000 — or the same as a three-bedroom house."Read more of this story at Slashdot.

Despite Controversy, Federal Wiretaps On the Rise
Posted: July 1st, 2011, 4:22am CEST by timothy
Tags: privacy
coondoggie writes with a report that "Federal and state requests for court permission to intercept or wiretap electronic communications increased 34% in 2010 over 2009 with California, New York, and New Jersey accounting for 68% of all wire taps approved by state judges. According to the 2010 Wiretap Report, released today by the Administrative Office of the United States Courts (AOUSC) the most frequently noted location in wiretap requests was 'portable device,' a category that includes cellular telephones and digital pagers."Read more of this story at Slashdot.
