Regular Slashdot contributor Bennett Haselton
writes in to say "The December 1st release of Psiphon has sparked renewed interest in
the various software programs that can help circumvent Internet censorship
in China, Iran, and other censored countries. (Some of this interest
undoubtedly being motivated by the fact that many of these programs also
work for getting around blocking software at work or school.) Have you
ever wanted to understand the science behind these programs, the way that
mathematicians and codebreakers understand the magic behind PGP? If you
loved the mental workout of reading "Applied Cryptography",
have you ever wanted a tutorial to do the same for Psiphon and Tor and
other anti-censorship programs?"
