Previously I blogged about a lecture series in cryptography called Cryptonite, this is an initiative of Hackerspace Budapest. Last week I gave a presentation at Cryptonite, I spoke about following two topics:
Man vs Machine - If no trusted computer is available, can a human apply strong cryptographic protection (encryption/authentication) to a message, and if yes, how? Literature calls this area as human-computer cryptography or pencil-and-paper cryptography.
Alternatives to PKI-based SSL on the web - I spoke about the CA/Browser Forum's attempts for reinforcing PKI, and also about concepts radically different to having a CA hierarchy such as those of the Certificate Patrol and Perspectives/Convergence projects. The audience also added MonkeySphere as a similar initiative.
My slides are in English, but I spoke in Hungarian.
