Talk for ICT group in University of Calgary

I had a great and friendly talk in Calgary with ICT group members. They gave me an opportunity for presenting my PhD research. Here is my slides.

Identity based cryptosystems

I did a quick reading on "identity-based" cryptography. The idea was firstly proposed by Shamir in 1994: "Identity based cryptosystems and signituare schemes".
The idea is to get rid of public key exchange protocols, third trusted parties, CAs in an assymetric (public/private) key cryptosystem by using the pre-known id of the users (like email address, social number, etc.) as their public key.

what is a public key's life cycle?

Although the key life cycle seems to be an important factor in cryptosystems' security, I couldn't find a solid refrence on the topic. After hours of web search, a discreption on RSA Lab's website is satisfactory.
