Strengthening Password Authenticaiton using SFE

A prototype of our SFE-based authentication protocol is available. Click here to download. The file contains a modified version of the dropbear-0.52 SSH client and server which implements SFE-based password authentication over an SSH connection.

Privacy Preserving Genomics Tools

PPGT is the implementation used in our paper "Practical Privacy for Genomics Computation". It consists of a general purpose circuit compiler for creating and evaluating secure circuits, and some privacy preserving protocols designed to evaluate edit distance and the Smith-Waterman metric as described in the paper

A prototype of the program is now available. Click here to download.
