I'm a baby-boomer Canadian currently working in China. I've spent two substantial chunks of my career as a teacher — 1978-83 and 2002-10 — mainly because that is a good way to support travel. At other times I've worked in computing, mostly as a technical writer but a bit of everything else too. My current job is as a technical editor at Shanghai Jiao Tong University, improving the English in papers by Chinese graduate students that are about to be submitted to journals or conferences.

I am quite active on Wikitravel, where I'm an admin, and sometimes contribute to other wikis. See my Wikitravel user page: [1].

My academic qualifications are a BA in Psychology and a Certificate in Teaching English as a Second Language, both from Carleton U in Ottawa. I also did some work toward an M Phil in computational linguistics at U of Birmingham, UK, but did not complete that degree.

I'm interested in computer security and cryptography. I think my November 2008 paper on the e-print website of the International Association for Cryptologic Research,,Exploring Cipherspace: Combining stream ciphers and block ciphers, is fairly interesting.

My Erdos number is five, via Carlisle Adams, Michael Wiener and Ron Rivest.

I wrote most of the documentation for the FreeS/WAN project, a Linux implementation of the IPsec encryption protocols. I have permission to re-use that text here User_talk:Sandy_Harris/Permission.

I keep a list of User:Sandy_Harris/Articles in my main area of interest.
