Identity-Based Encryption

Dan Boneh gave a talk at Princeton today about some recent developments in cryptography based on algebraic geometry. One of these tools is identity-based encryption which is public-key encryption where the public key is just a user's identity such as their email address.

Dan's group has an implementation of the system for Outlook, Yahoo Mail and some other systems. If you want to be the first on your block using the latest and greatest encryption or just want more information check out the IBE web site.

Personally, I send all my email in cleartext. If anyone goes through the hassle of capturing it they will only discover what a boring person I am.
