Policy-agile encrypted networks via secure function computation

Recent developments in cryptography in the areas of secure multi-party function computation and homomorphic encryption enable new policy-agile encrypted networking capabilities. By applying algorithms that can securely perform encrypted operations on encrypted data without decryption of either, context- and content-aware decisions can be performed (or policy rules applied) within a new advanced “black core” network while preserving confidentiality of the mission context and content. We discuss three application areas-with applicability to defense, law enforcement, intelligence community, and commercial networks, especially when resource sharing and collaboration across multiple organizations must occur over out-sourced third party infrastructures-that are enabled.
