A minor update to the TrueCrypt free open-source disk encryption tool arrived today, version 7.1a, some five months since the release of the previous stable version. I have upgraded several systems to the new version without issue, including two laptops with pre-boot authentication and full disk encryption, and a media server where I use TrueCrypt to create and work with encrypted file-container volumes as part of my backup process. …
In 2010, semiconductor manufacturers began migrating the algorithmically intensive portions of the AES cipher on-die in the form of the AES-NI instruction set. Many cryptographic APIs and applications have enabled support for this new technology, and none hesitate to tout the promise of major performance improvements. Intel demonstrates 3x to 10x acceleration versus pure software implementations, while the authors of TrueCrypt set the expectation of 4x to 8x speed gains. Can these performance boosts be recognized in practice, and how much of these gains can be captured in present day, real world scenarios? …
Sparse remarks in the changelog for today’s updated release of the TrueCrypt free open-source disk encryption tool, version 7.1, the first new release in nearly a year. Primarily it looks like they have added support for Mac OS X 10.7 Lion. I venture the usual assessment that this update may safely be viewed as optional for users already running at least TrueCrypt 7.0, the most recent major release, absent those experiencing any specific issues. …
A minor bugfix update to the TrueCrypt disk encryption tool, version 7.0a, was released yesterday. The release notes cite minor bugfixes only, so this update may be viewed as optional for users already running at least TrueCrypt 7.0, the most recent major release, absent those experiencing any specific issues. …
A major, feature-rich update to the TrueCrypt disk encryption tool hit the wire yesterday, notably adding support for Intel’s on-die AES-NI instruction set in Westmere class processors and newer. The authors claim a juicy 4 to 8 times performance leap for hardware-accelerated AES over a pure software implementation. …
Two previous rounds of analysis using IP geolocation with Whois (Part 1 and Part 2) revealed that 40% to 45% of network intrusion attempts arriving at my public-facing SSH port could be traced back to Chinese hackers, and 20% to 25% to attackers in Russia and Eastern Europe. The tally is now in from a third round of observations, boasting a significantly longer integration period (more than four months versus about six to seven weeks in the earlier rounds) and yielding plenty of interesting and even unexpected results. …
Late breaking articles from the New York Times and Wall Street Journal this evening caught my eye, wherein one seriously pissed off Google Inc opens up a surprisingly hard line against Beijing: …
A minor maintenance update to disk encryption tool TrueCrypt was released yesterday. The release notes cite bugfixes only, so this update may be viewed as optional for users already running at least TrueCrypt 6.1a, the last “highly recommended” maintenance update, absent those experiencing any specific issues. …
The latest maintenance release of disk encryption tool TrueCrypt made general availability today, adding most notably updated operating system support, including support for Windows 7 and Mac OS X 10.6. The release notes don’t indicate anything terrifically critical, so this release may be viewed as optional for users already running at least TrueCrypt 6.1a, the last “highly recommended” maintenance update. That being said, I’ll be immediately updating all installations. …
Time to tally up the new results since my last report on network intruder geolocation using Whois. Will the trend showing two-thirds of attackers as hailing from China, Russia and the former Soviet bloc hold for this new integration period? Place your bets. …
