- A modest proposal
I should be allowed to set up a hidden camera at the doorstep of the Dundas West subway station in Toronto, which is across the street from the local Catholic school, and take photos up the skirts of teenage girls (or anybody else wearing a skirt) as they enter and leave the building.

- Slashdot "multicore" exploit explained
As is often the case with Slashdot coverage of security vulnerabilities, this article on a supposedly multicore-related exploit, and the Register article it links to, are so poorly written that it's not at all clear what they're talking about or why it would be a problem. The comments don't help either, since they go off in different directions based on other related and unrelated issues instead of the actual supposed problem. The real underlying issue turns out to be much less threatening than the article suggests.
(16 September 2007)- Scratch-and-win equals DRM
The CBC has been following a story about scratch-and-win lottery tickets, and it occurs to me that what's really going on with that is exactly the same thing that's going on with DRM/TPMs (Digital Rights Management and Technological Protection Measures). The real issue is a faulty reliance on physical security of a trusted device in untrusted hands.
(23 November 2006)- Bar code scanners and in-band commands
I've been interested in bar codes recently, and while pricing low-end scanners, I noticed something that seems to be a significant, and not widely publicized, security issue.
(9 August 2006)- Quantum cryptography without the quantum?
Laszlo Kish at Texas A&M has announced a scheme for doing something very much like "quantum cryptography" without the need for messy individual-photon apparatus. Here's a PDF of the paper. Since this is the sort of thing that my readers are interested in and I know a bit about, I thought I'd comment even though it has run on Slashdot already.
