Two of my major interests converged fascinatingly at the recent RSA conference in San Francisco. One is information security. The event is named after three famous cryptographers (Rivest, Shamir and Adleman), and I’ve been a fan of them and this conference for a long time. How long? I taught Canada’s first information security course on Oct. 14, 1977. The number of people who can challenge that claim gets smaller every year.
