In Cambridge, Mass., not too far from the Charles River, which cuts near Harvard and M.I.T., David Pearson is attempting to build an un-hackable network. Pearson is a division scientist at BBN Technologies, a private research company in Cambridge, Mass., which is most famous for building, in 1969, the first few nodes of a computer network connecting its headquarters to Harvard University and Boston University that over time would evolve into the Internet. Now the firm has built a network it says is impervious to hackers.

Schneier's fame drives Counterpane's success

Bruce Schneier, founder and chief technical officer of Counterpane Internet Security, might be as close as the computer security industry gets to its own celebrity. Although not as well known as Larry Ellison at Oracle or Bill Gates at Microsoft, Schneier is still the public face of his company, recognized by industry insiders as one of their gurus. Businesses hire Counterpane to guard their networks from hackers and viruses in the same way a nervous homeowner would pay a home-security provider like ADT to watch for fires or burglars.

The CS2 Block Cipher

In this paper we describe our new CS2 block cipher which is an extension of the original CS-Cipher. Our new design inherits the efficiency of the original design while being upgraded to support a larger block size as well as use a slightly improved substitution box. We prove that our design is immune to differential and linear cryptanalysis as well as argue it resists several other known attacks.

Researchers: Digital encryption standard flawed

In a three-page research note, three Chinese scientists -- Xiaoyun Wang and Hongbo Yu of Shandong University and Yiqun Lisa Yin, a visiting researcher at Princeton University -- stated they have found a way to significantly reduce the time required to break a algorithm, known as the Secure Hashing Algorithm, or SHA-1, widely used for digital fingerprinting data files. Other cryptographers who have seen the document said that the results seemed to be genuine.

Researchers find security flaw in SHA-1

Security experts are warning that a security flaw has been found in a powerful data encryption algorithm, dubbed SHA-1, by a team of scientists from Shandong University in China. The three scientists are circulating a paper within the cryptographic research community that describes successful tests of a technique that could greatly reduce the speed with which SHA-1 could be compromised.

Why Not Truth?

Ultimately cryptographers want some form of quantum repeater--in essence, an elementary form of quantum computer that would overcome distance limitations. A repeater would work through what Albert Einstein famously called "spukhafte Fernwirkungen," spooky action at a distance.

Quantum leap

It began 25 years ago in the warm coastal waters of Puerto Rico when a stranger swam over to Gilles Brassard and struck up a conversation about using quantum physics to make bank notes impossible to counterfeit. "I had no idea who he was," recalled Brassard, then a 24-year-old prodigy and computer-science professor at the Universite de Montreal. "He just started talking nonsense about quantum physics."

Hashing out encryption

Federal agencies have been put on notice that National Institute of Standards and Technology officials plan to phase out a widely used cryptographic hash function known as SHA-1 in favor of larger and stronger hash functions such as SHA-256 and SHA-512.

The encryption factor

Quantum computing is set to revolutionise the way we work. Trouble is, it could crack any of today's security codes in a fraction of a second, says Charles Arthur.When bankers and spies begin to worry about advances in computing, the rest of us would do well to take notice. What makes them edgy are the advances being made in "quantum computing", which is, as might be expected from the name, as entangled and confusing a field to understand as the branch of physics on which it is based - quantum mechanics.

Microsoft Downplays Office Encryption Weakness

A security researcher has issued an alert for a "serious security flaw" in the way document encryption is implemented in Microsoft's Word and Excel products, warning that a widely-used encryption algorithm is being misused by the software giant.

Adding strong security from day one

Adding security to constrained devices is not an easy task for developers who need to accommodate a range of new features without compromising usability. Experience has shown that building security in at the design stage yields better results from a security and performance perspective. Therein lies the challenge. It’s no secret that most cryptographic systems are computationally taxing. Such is not the case with Elliptic Curve Cryptography, or ECC, which has the most strength per bit of any known public key system today and consequently is ideally suited for resource-constrained devices.

Secure E-Mail and Public Key Cryptography: Together At Last?

With its ability to authenticate, digitally sign, and encrypt messages, public key cryptography seems like a natural fit for protecting e-mail: With one solution, you can ensure the integrity of the content and prove the identity of the sender. But public key cryptography is akin to peace in the Middle East--everyone agrees it's a good idea, but the associated complexities can derail implementation. . . .

Spammers using sender authentication too, study says

New technology for identifying the sender of e-mail messages has not been widely adopted despite backing from software giant Microsoft Corp. and may not be effective at stopping unsolicited commercial e-mail, otherwise known as spam, according to a survey by e-mail security company CipherTrust Inc. . . .

DES Defies Demise

The deeply embedded crypto algorithm lives on in 3DES, but that standard demands careful design and informed choices.You have only until Sept. 9 to object to the federal government's proposed decertification of the Data Encryption Standard. After reading the proposal, I'm tempted to complain that it would not leave DES sufficiently dead. . . .

An Illustrated Guide to Cryptographic Hashes

With the recent news of weaknesses in some common security algorithms (MD4, MD5, SHA-0), many are wondering exactly what these things are: They form the underpinning of much of our electronic infrastructure, and in this Guide we'll try to give an overview of what they are and how to understand them in the context of the recent developments. . . .

Opinion: Cryptanalysis of MD5 and SHA: Time for a new standard

At the Crypto 2004 conference in Santa Barbara, Calif., this week, researchers announced several weaknesses in common hash functions. These results, while mathematically significant, aren't cause for alarm. But even so, it's probably time for the cryptography community to get together and create a new hash standard. . . .
