This thesis focuses on the practical aspects of general two-party Secure Function Evaluation (SFE). A new SFE protocol that allows free evaluation of XOR gates and is provably secure against semi-honest adversaries in the random oracle model is given.

We address basic leaks of private information and also consider other aspects of privacy policies supported by the Platform for Privacy Preferences (P3P) an...

This report is an extension and partial update of de la Fuente and Ciccone (2002).
