Note: I am no longer maintaining this page. For a frequently updated (and much more complete) list of IBE cryptosystems visit the pairing-based crypto lounge.

This page contains a list of resources (research papers, applications, links, etc.) related to identity-based encryption (IBE) (or identity-based cryptography (IBC) if you prefer). If you need to find a paper listed here you can use IACR eprint, Citeseer or Google. If you want me to add something to this list, or update an entry, please don't hesitate to contact me. Moreover, please note that the list is not sorted in any way, and that some entries are more complete than others.
