Project description
A deeper look at proof systems
Verifiable computing has emerged as a key component in the future growth of blockchains and cloud computing. Found in a variety of technical applications involved in real-world technologies, it allows a weak verifier to ascertain the correctness of complex computational statements. The EU-funded VERICOMP project will improve our understanding of proof systems with polynomial-time proof generation, to explore their practical applicability and to investigate their connections with foundational questions in cryptography and in complexity theory. By focusing on interactive proof systems for tractable computations, the project will provide a complete characterisation of the complexity of proving and verifying general statements. In turn, this will facilitate breakthroughs in the study of related proof system notions like cryptographic arguments.
Objective
Proof systems allow a weak verifier to ascertain the correctness of complex computational statements. Efficiently-verifiable proof systems are fundamental objects in the study of computation, and have led to some of the deepest and most celebrated insights in cryptography and in complexity theory.
The vast and rich literature on proof systems focuses primarily on proving the correctness of intractable statements, e.g. ones that are NP-complete. While the verification can be efficient, the proofs themselves cannot be generated in polynomial time. This limits the applicability of such proof systems, both from a theoretical perspective and in their real-world impact. This proposal aims to obtain a comprehensive understanding of proof systems with polynomial-time proof generation, to explore their practical applicability, and to investigate their connections with foundational questions in cryptography and in complexity theory.
Our study will focus primarily on interactive proof systems for tractable computations. The proposed research aims to revolutionize our understanding of these foundational objects by providing a complete and tight characterization of the complexity or proving and verifying general statements, by achieving breakthroughs in the study of related proof system notions, such as cryptographic arguments, and by building a fine-grained “algorithmic” theory of proof systems for central polynomial-time computational problems.
Our research will leverage these advances towards diverse applications: from real-world security challenges, such as verifying the correctness of computations performed by the cloud and cryptographic “proofs of work”, to a complexity-theoretic understanding of the complexity of approximating problems in P and of solving them on random instances.
