  • Why You Should Never Listen to the Media About Security | Irreal
    were going to write about security they would actually know something about it Yet here s the The New York Post decrying the sale of NYC 1620 keys by some rogue locksmiths and the implications this has for security and terrorism and God knows what else The problem is that along with the article they published a large picture of the key Now everyone can have one even without paying the 15 50 the locksmiths were asking None of this is news Remember when the TSA allowed The Washington Post to publish pictures of their luggage master keys and the widespread ridicule of many in the press You d think that someone at the Post a large and sophisticated paper would have heard about that Apparently not And why didn t the reporter who was after all writing about security know this No one expects reporters to be able to explain say the intricacies of RSA encryption but they should know by now that if you publish a picture of a key it s trivial to make a copy This entry was posted in General and tagged Security Bookmark the permalink Some Comment DWIM Tricks Fingerprint Sensors Really Do Improve Security Search for Recent Posts Elisp Summary Emacs for Prose FISA Abandons the Fourth Amendment Again Blogging with Org Mode and Nikola How to Keep Emacs Running Across an X Crash Recent Comments Mike Zamansky on Blogging with Org Mode and Nikola Phil on How to Keep Emacs Running Across an X Crash Sebastian Christ on European Quotation Marks NoonianAtall on A Hyper Key on Any USB Keyboard Kris on An Example of Why Reproducible Research Matters Links Useful Emacs Commands Archives April 2016 March 2016 February 2016 January 2016 December 2015 November 2015 October 2015 September 2015 August 2015

  • The Dangers of Government Held Master Keys | Irreal
    the TSA was merely annoying they persuaded luggage manufacturers and travelers to use locks for which the TSA had master keys Recently the TSA allowed the Washington Post to take a picture of the keys But once you have a picture of a key it s trivial to make a copy and indeed that has already happened so now no one s baggage is safe from say a dishonest baggage handler 1 Does anyone doubt that some equally incompetent government agent will similarly reveal the golden keys that the FBI so fervently desires If you do how much do you think criminals or unfriendly nation states would be willing to pay for those keys As Bruce Schneier says in the post linked above the problem with backdoors whether cryptographic or physical is that they re fragile Footnotes 1 Matt Blaze s point about the safety of these locks As a practical matter the photos of the TSA keys isn t such a big deal Using a key is actually slower than picking those locks matt blaze mattblaze September 8 2015 is beside the point What matters here is that the government asked for special access and then was careless with safeguarding it This entry was posted in General and tagged Privacy Security Bookmark the permalink Using Emacs Keychords They Always Lie Search for Recent Posts Elisp Summary Emacs for Prose FISA Abandons the Fourth Amendment Again Blogging with Org Mode and Nikola How to Keep Emacs Running Across an X Crash Recent Comments Mike Zamansky on Blogging with Org Mode and Nikola Phil on How to Keep Emacs Running Across an X Crash Sebastian Christ on European Quotation Marks NoonianAtall on A Hyper Key on Any USB Keyboard Kris on An Example of Why Reproducible Research Matters Links Useful Emacs

  • We Don’t Care About No Stinkin’ Keys | Irreal
    printer can get one The TSA s loss of the master keys seemed like a cogent argument against trusting the government with the far more important and potentially devastating access to our digital communications Here s another the TSA s reaction to the loss of the keys is Meh Most people don t lock their bags anyway Besides the bags are under our control so they re safe Even if you believe that anodyne fairy tale it says nothing about say a hotel bell hop who suddenly has access to your luggage As a practical matter the locks are terribly insecure with or without the master keys but the government did promise that the locks would ensure the safety of your luggage while enabling legitimate government access Yet when that same government lost control of the keys their attitude was So what It s not our problem Is there any reason to believe that the FBI would be any less cavalier if they lost the encryption master keys Is there any reason to believe that the FBI would be more competent than the TSA is safeguarding those keys The possible loss of the encryption master keys is only one and not the strongest argument against the imposition of these keys but it s worth remembering what the government says when they mess up and compromise their exceptional access It s not our problem This entry was posted in General and tagged Privacy Bookmark the permalink Adjusting Text Size in Emacs The EFF Talks Encryption Search for Recent Posts Elisp Summary Emacs for Prose FISA Abandons the Fourth Amendment Again Blogging with Org Mode and Nikola How to Keep Emacs Running Across an X Crash Recent Comments Mike Zamansky on Blogging with Org Mode and Nikola Phil on How to Keep
