With a weak kitchen magnet this can take many passes and a fair amount of time. In fact if all you have is a fridge magnet you may be better off scraping the strip off. However a more powerful magnet can erase the card fairly quickly. See http://www.creditcards.com/credit-card-news/video-magnets-make-credit-card-mag-stripe-not-work-1457.php for details. ...

I wrote the security technical advisor to the movie Sneakers, Mr John Strauchs. Sneakers includes a scene where intruders increase the ambient temperature of the room in order to defeat the IR motion sensors. John wrote the technical details of that scene (including the purposeful errors). John is a former operations officer at the CIA, and designs ...

Your approach reminds me of a really interesting talk at the Blackhat 2013 about defeating physical security measures. There it was demonstrated that some PIR motion sensors can be turned off by using a lighter from medium or low distance. To get closer to the sensor you can use some kind of 'shield' which has room temperature and blocks your body heat. I ...

Yes, I believe the terminal ID refers to a username/password, and yes it is rather ambiguous. I think the idea it is trying to convey is that log in credentials prevent user operational access to a computer system, but do not actually prevent access to the computer itself. Its easy to argue that TV monitors do not prevent unauthorized people from entering ...

The solution for you does exists I presume - use an onboard memory, better take a look for SoC-integrated memory, btw. the crucial part for memory aquisition or even for cold boot is an ability to ACTUALLY eject a memory or be able to boot from a pendrive, for example. uBoot+NAND will save you, I suppose. Start looking from Cubieboard 1 or 2 as an example of ...

Some filesystems support DAX, which stands for Direct Access. It's a feature which bypasses the page cache, so a filesystem encrypted with TRESOR will not leak much if any unencrypted data when you read and write to it. You can put a file in tmpfs and create a loopback device and encrypt it with TRESOR, then format it with a filesystem that supports DAX. ...

A potential attack vector you haven't covered so far is something called "acoustic cryptanalysis", although I don't know if this is relevant in your case. Some experts could actually determine a RSA key using the sound the CPU makes (which humans aren't able to hear). http://www.cs.tau.ac.il/~tromer/acoustic/ I haven't thought of a practical solution as of ...

Before we start, a quick word about how USB works. A USB device connects to a piece of hardware inside the computer called the USB host controller. This decodes the complex USB protocol, which, much like a network protocol like TCP, contains packets, checksums, the equivalents of SYNs, ACKs, etc. The USB host controller decodes each individual connected USB ...
