Privacy Protocol for Internet Computer (ICP)

This paper introduces a privacy-preserving transfer architecture for the Internet Computer (ICP). It addresses the need for secure and private data transfer by decoupling deposit and retrieval, using ephemeral intermediaries, and employing a novel Rank-Deficient Matrix Power Function (RDMPF) for encapsulation. The design aims to provide sender identity privacy, content confidentiality, forward secrecy, and verifiable liveness and finality. The fact that it's already in production (ICPP) and has undergone extensive testing adds significant weight to its practical relevance.
