3 The Problem There is no single Public Key Infrastructure Discrete Trust Domains abound Different systems incorporate differing –Technical Solutions –Policy Decisions The Federal Government needs a mechanism for reliance on external Trust Domains. Interoperability is the CHALLENGE –Technical Interoperability –Policy Interoperability

4 Islands of Trust
