This thesis describes a new trust model for OpenPGP encryption. This trust model uses conditional rule-based trust to establish key validity and trust. This thesis describes "Trust Rules" that may be used to sort and categorize keys automatically without user interaction. "Trust Rules" are also capable of integrating key revocation status into its calculations so it too is automated. This thesis presents that conditional trust established through "Trust Rules" can enforce stricter security while reducing the burden of use and automating the process of key validity, trust, and revocation.
