Speed Found to be Key to Galaxy Formation
QuantumCrypto writes "The All-wavelength Extended Groth strip International Survey (AEGIS), a collaborative effort involving nearly 100 scientists in half a dozen countries, revealed a new principle in the formation of all galaxies, from disk-like spirals, cloud-like ellipticals, and just irregulars. In essence the morphology of the galaxies depends on total mass involved and the internal speed it generates. 'By defining a new speed indicator, their analysis has managed to make sense out of very chaotic-looking objects,' said Sandra Faber, professor of astronomy and astrophysics at the University of California, Santa Cruz." -
A Network Sniffer On Steroids
QuantumCrypto writes "Errata has developed a new network sniffer, dubbed 'Ferret,' that looks for traffic using 25 protocols, including those for the popular instant message clients as well as DHCP, SNMP, DNS and HTTP. This means the sniffer will capture requests for network addresses, network management tools, Web sites queries, Web traffic and more. 'You don't realize how much you're making public, so I wrote a tool that tells you,' said Robert Graham, Errata's chief executive. Errata has released the source code to this version 1.0, 'feature-poor and buggy' tool on its site. Anyone with a wireless card will be able to run it, Graham said." -
The Blackest Material
QuantumCrypto writes "Researchers at Rensselaer Polytechnic Institute have created 'the world's first material that reflects virtually no light.' This anti-reflection technology is based on nanomaterial and could lead to the development of more efficient solar cells, brighter LEDs, and 'smarter' light sources. In theory, if a room were to be coated with this material, switching on the lights would only illuminate the items in the room and not the walls, giving a sense of floating free in infinite space." -
SETI Finally Finds Something
QuatumCrypto writes "SETI@home is a distributed processing client from UC Berkeley that installs on the volunteers' home computers and harnesses their processing power in the search for extraterrestrial intelligence. So far nothing noteworthy has comeout of this massive project... that is until today! One of the volunteers was able to track down his wife's stolen laptop using the IP address that SETI@home client reports back to the server. After getting back the laptop his wife said, 'I always knew that a geek would make a great husband.'" -
Digital Credentials Offer Enhanced Privacy
John Q Random writes "Stefan Brands's company credentica.com announced their U-Prove library and SDK implementing ID tokens — also known as digital credentials or private credentials. (Private Credentials are a cool PKI replacement and anonymous e-cash tech that allows you to prove certified attributes like age, credit rating, group membership, etc. without revealing who you are; to allow you to have a digital life without the digital dossier effect inherent in a central databases.) Following this announcement, Adam Back announced credlib, an open source implementation of Brands credentials (and the older more basic Chaum certificates). These developments relate to recent news from IBM's Zurich labs on their identity-mixer project (previously discussed on Slashdot) that is based on the less efficient Jan Camenisch and Anna Lysyanskaya credentials." -
Sign Language Via Cell Phone
QuatumCrypto writes "A project is underway at the University of Washington to enable real-time sign language communication via cell phone. Because of the low-bandwidth wireless cell phone network, a new compression scheme is necessary to capture only the bare essential components of signing to minimize data transfer. Although text messaging is a viable alternative for everyone, signing — like speech — is a much faster and more convenient form of communication." -
A Competition To Replace SHA-1
SHA who? writes "In light of recent attacks on SHA-1, NIST is preparing for a competition to augment and revise the current Secure Hash Standard. The public competition will be run much like the development process for the Advance Encryption Standard, and is expected to take 3 years. As a first step, NIST is publishing draft minimum acceptability requirements, submission requirements, and evaluation criteria for candidate algorithms, and requests public comment by April 27, 2007. NIST has ordered Federal agencies to stop using SHA-1 and instead to use the SHA-2 family of hash functions." -

U.S. Gov't To Use Full Disk Encryption On All Computers
To address the issue of data leaks of the kind we've seen so often in the last year because of stolen or missing laptops, writes Saqib Ali, the Feds are planning to use Full Disk Encryption (FDE) on all Government-owned computers. "On June 23, 2006 a Presidential Mandate was put in place requiring all agency laptops to fully encrypt data on the HDD. The U.S. Government is currently conducting the largest single side-by-side comparison and competition for the selection of a Full Disk Encryption product. The selected product will be deployed on Millions of computers in the U.S. federal government space. This implementation will end up being the largest single implementation ever, and all of the information regarding the competition is in the public domain. The evaluation will come to an end in 90 days. You can view all the vendors competing and list of requirements." -

Why Not Use Full Disk Encryption on Laptops?
Saqib Ali asks: "According to the 2006 Security Breaches Matrix, a large number of the data leaks were caused due to stolen/missing laptops. Mobile devices will be stolen or lost, but one way to easily mitigate the harm is to use Full Disk Encryption (FDE) on all mobile devices. So, why don't we encrypt all our HDDs?" "Cost, and performance impact are the usual arguments.
Analysis shows that the access time increases by 56%-85% after FDE. As HDDs fills up the fragmentation increases and so will the file access time. With FDE, the swap file (system's virtual memory) gets encrypted as well. This will impact the system's performance noticeably when the virtual memory is being used more often.
Encryption key & password management blues follow. What happens when the user forgets his/her new FDE password? How to manage the encryption key backup files? Who has possession of the backups of the encryption keys? What about when the users quits and does not hand over the password / encryption keys? Who can access the system and its encrypted files? How frequently does the password need to be changed? How to prevent the user from writing the passwords down? Using hardware token (RSA Token, smartcard etc) can alleviate many of the password management issues. But these hardware tokens are costly!
Cost for Full Disk Encryption solutions ranges from $0-$300.
Is it not worth using Full Disk Encryption on mobile devices after all the data leaks we have seen in the last few years?" -
