6   Using PGP

Ensemble supports the use of PGP for authenticating members of groups. This work is complete, and several papers have been pusblished with our results. We do not guarantee bullet proof security, however, we do not know of any remaining security bugs. All the Ensemble demo applications support the use of PGP, including mtalk, wbml, and ensemble. These are the instructions for using PGP. Note that PGP is supported for all platforms. Now when you run an application only members that start with the same shared key or who can authenticate each other through PGP will merge into the same group. If you run into problems, you can access PGP's debugging output through the additional command-line arguments, -trace PGP.
