Formal Specification and Verification of the Intrusion-Tolerant Enclaves Protocol

In this paper, we present a correctness proof of the Intrusion-tolerant Enclaves protocol [10]. Enclaves is a group-membership protocol. It assumes a Byzantine failure model, and has a maximum resiliency of one third. To carry out the proof, we adaptively combine a number of techniques, namely model checking, theorem proving and analytical mathematics. We use the..
