We start with presenting motivation and goals for the Future Internet, and reviewing basics of trust in computing.

The Pervasive Trust Foundation (PTF) for the Future Internet is proposed next. This includes presenting motivation for trust foundation for the Future Internet, showing placement of security services and mechanisms within the architecture, and trust considerations for security services.

Inefficient operation of the PTF-based architecture is the main obstacle to making such architecture a reality. There are two classes of approaches that can reduce operational costs. First, inherent PTF properties result in automatic cost-saving. Second, additional cost-saving techniques --such as leveraging high-trust enclaves, or using enclave "insurers"-- can be used.

The architectural principles presented here are a position statement, and their practical verification will require substantial research efforts.
