Title: Securely Obfuscating Re-Encryption

Abstract:
In this talk I will present a recent paper about code obfuscation
which is the first postive  result for a traditional crypto functionality,
re-encryption functionality.
Note that other positive results in the standard model only apply to very simple
point functions.

To make the results meaningful, the authors use a new definition of obfuscation.
