Radiation Hardened, Reprogrammable Internet Protocol Encryptor

Our architecture builds on the basic tenets of high assurance cryptographic design, and provides a reprogrammable, modular architecture that: 1) Ensures integrity and confidentiality of information 2) Provides authentication and non-repudiation services. 3) Both physically and logically separates the security and non-security functions to support NSA evaluation and certification. 4) Identifies and allocates the security functions that must be implemented using high assurance design techniques. 5) Object oriented approach to security and cryptographic functions and implementation, and 6) is radiation hardened. The Radiation Hard Reprogrammable Internet Protocol Encryptor (RH-IPE) is based on the PSIAM-II Cryptographic Module and is designed using available commercial Field Programmable Gate Arrays, with the goal of maximizing re-programmability by allowing for the architecture to be updated using newer VHDL code. The design is minimizes re-certification activities as long as the security design rules and techniques used in the PSIAM-II design and embedment are strictly adhered to; plus provides a direct path for radiation hardening. The RH-IPE is based on a highly redundant architecture, where all critical functions are performed in parallel using similar logic that operate independently, with all critical decisions compared by redundant check functions to assure 100% consistency of results.
