Encryption circles are buzzing with news that mathematical functions embedded in common security applications have previously unknown weaknesses. The excitement began Thursday with an announcement that French computer scientist Antoine Joux had uncovered a flaw in a popular algorithm called MD5, often used with digital signatures. Then four Chinese researchers released a paper that reported a way to circumvent MD5 and other algorithms. . . .

Interview with Bruce Schneier, Counterpane Internet Security

Bruce Schneier, founder and CTO of Counterpane Internet Security, is one of the world's foremost security experts and author of the influential books Applied Cryptography, Secrets & Lies and Beyond Fear. His free monthly newsletter, Crypto-Gram, has over 100,000 readers. Interviewed by Glyn Moody, he discusses the lack of accountability of software companies, security through diversity, and why he would rather re-write Windows than TCP/IP. . . .

SSH Authentication: A Basic Overview

SSH is one of the premier Security tools in use today. SSH is most commonly used to gain a remote shell, but it can be used for file transfers, to display remote X applications on a local machine, and even to securely connect to services that lack encryption. Unfortunately, many who use it from day to day don't have a good understanding of how it actually works. Many people know that SSH1 is deprecated, and that SSH2 has taken its place, but how many know how authentication actually works for both? I didn't, and that bothered me, so I set out to do some research. . . .

How a Digital Signature Works

The trick of public key encryption -- the best known approach is called RSA for the initials of its inventors -- is that one key can be used to scramble the data while a different, mathematically related, key is used to unscramble it. When you download a digitally signed program, the first thing your computer does is check the Web site's digital certificate. It then queries the CA that issues the certificate to make sure it's still valid and to obtain the public key. . . .

Cryptography and the Open Source Security Debate

I've been reading Bruce Schneier's Book on cryptography for the last couple of days, and one of the main concepts in the text struck me as interesting. One of the points of discussion when looking at the security of a given algorithm is its exposure to scrutiny. Bruce explicitly states that no one should ever trust a proprietary algorithm. He states that with few exceptions, the only relatively secure algorithms are those that have stood the test of time while being poured over by thousands of cryptanalysts. . . .

Quantum Crypto Network Debuts

Quantum cryptography has the potential to guarantee perfectly secure communications, but until now all of the prototype systems have been point-to-point links rather than networks that share connections. . . .

Breaking codes: An impossible task?

Recent reports that the United States had broken codes used by the Iranian intelligence service have intrigued experts on cryptology because a modern cipher should be unbreakable. Four leading British experts told BBC News Online that the story, if true, points to an operating failure by the Iranians or a backdoor way in by the National Security Agency (NSA) - the American electronic intelligence organisation. . . .

When encryption can be misleading

Gadi Evron, an information security researcher based in Israel, generally signs his posts to the list with his PGP signature, due to the fact that his email address is constantly used by spammers. Anyone who wants to verify an signed email is actually from the person claiming to send it, can do so. . . .

RSA founders give perspective on cryptography

The famous cryptographers Leonard Adleman, Ronald Rivest, and Adi Shamir - the developers of the RSA encryption code - received the Association for Computing Machinery's 2002 Turing Award "for their seminal contributions to the theory and practical application of public-key cryptography." Their Turing Award lectures, given last June, are available online. . . .

Book Review: Malicious Cryptography

Most people are familiar with malware- viruses, worms, Trojans, etc.- and most people are familiar, at least with the concept, of cryptography. However there are far fewer people that truly understand either of these technologies, and even fewer still who understand how the two can be combined to create the next generation of malicious code. Good reading, but a certain level of understanding of malware and cryptography is needed in order to follow the information in this book. . . .

Tales from the Crypto World

Paul Kocher, president and chief scientist of Cryptography Research, came to prominence in the industry by breaking things. In 1998, the company cracked security on smart cards by monitoring how much power their internal microprocessors used. Kocher also came up with the software inside Deep Crack, a machine tailored to crack encrypted documents. . . .

File And Email Encryption With GnuPG (PGP)

File and mail security is easy to achieve with the right tools. PGP has proven itself the leader, and GnuPG is the tool of choice in the Linux world. Anyone who has read this column a while knows I'm a bit obsessive about crypto. With the speed of modern or even old processors, there's no reason that there should be any cleartext transmissions on the Internet at all. . . .

Encryption: Building to Code

Data protection mandates in legislation like HIPAA and the Sarbanes-Oxley Act are making encryption more popular, but cryptography as a point solution is another story. Enterprises "aren't going out and searching for what product can solve everything out of the box," explains Adam K. Erickson, senior VP of worldwide sales and marketing for encryption middleware provider Eruces. "Rather, what they're tending to do is develop their own solutions in-house." . . .

Creating Secure Backups With GnuPG

GnuPG is a complete and free replacement for PGP. It is a valuable piece of software that is very easy to use and will serve our purpose for covering the topic of secure backups. I won't got into details in installing GnuPG as there are number of good installation guides around that pretty much cover this topic (faqs.org, linux-tutorial.info and web.bham.ac.uk). Depending on your server and administrator, GnuPG will be ither pre-installed, installed after bugging the administrator or installed by yourself if you have sufficient local privileges. . . .
