The current development is built above the HOL (Higher-Order Logic) Isabelle
theory and the formalization of protocols introduced by Larry Paulson. More
details are in his paper
🌐‹https://www.cl.cam.ac.uk/users/lcp/papers/Auth/jcs.pdf›: ∗‹The Inductive
approach to verifying cryptographic protocols› (J. Computer Security 6,
pages 85-128, 1998).

This directory contains a number of files:

▪ 🚫‹Extensions.thy› contains extensions of Larry Paulson's files with
many useful lemmas.

▪ 🚫‹Analz.thy› contains an important theorem about the decomposition of
analz between pparts (pairs) and kparts (messages that are not pairs).

▪ 🚫‹Guard.thy› contains the protocol-independent secrecy theorem for
nonces.

▪ 🚫‹GuardK.thy› is the same for keys.

▪ 🚫‹Guard_Public.thy› extends 🚫‹Guard.thy› and 🚫‹GuardK.thy› for
public-key protocols.

▪ 🚫‹Guard_Shared.thy› extends 🚫‹Guard.thy› and 🚫‹GuardK.thy› for
symmetric-key protocols.

▪ 🚫‹List_Msg.thy› contains definitions on lists (inside messages).

▪ 🚫‹P1.thy› contains the definition of the protocol P1 and the proof of
its properties (strong forward integrity, insertion resilience,
truncation resilience, data confidentiality and non-repudiability).

▪ 🚫‹P2.thy› is the same for the protocol P2

▪ 🚫‹Guard_NS_Public.thy› is for Needham-Schroeder-Lowe

▪ 🚫‹Guard_OtwayRees.thy› is for Otway-Rees

▪ 🚫‹Guard_Yahalom.thy› is for Yahalom

▪ 🚫‹Proto.thy› contains a more precise formalization of protocols with
rules and a protocol-independent theorem for proving guardness from a
preservation property. It also contains the proofs for Needham-Schroeder
as an example.
