Modeling and Analyzing Security Protocols with Tamarin
The Tamarin prover is an open-source analysis tool for cryptographic protocols. Given a specification of a protocol, possible adversaries, and the desired security properties, Tamarin either verifies the protocol or provides counter examples witnessing attacks. Tamarin is a robust and powerful analysis tool: it has been under development for over a decade and has reached a state of maturity where it can be applied to model and analyze a wide range of real-world cryptographic protocols. It is now one of the leading tools in this domain, with a wide and active user community spanning both academia and industry. The objective of this book is to help both researchers and practitioners to gain a general understanding of how Formal Methods tools like Tamarin can be used to analyze and improve the quality of real-world protocols. Moreover, we specifically showcase the Tamarin prover and provide guidance on its usage. In this sense, this book provides a user’s manual forTamarin. But it goes far beyond that, highlighting Tamarin’s underlying theory and its use in modeling and applications.

Security protocols are widely used to ensure secure communications over insecure networks, such as the internet or airwaves. These protocols use strong cryptography to prevent intruders from reading or modifying the messages. However, using cryptography is not enough to ensure their correctness. Combined with their typical small size, which suggests that one could easily assess their correctness, this often results in incorrectly designed protocols. The authors present a methodology for formally describing security protocols and their environment. This methodology includes a model for describing protocols, their execution model, and the intruder model. The models are extended with a number of well-defined security properties, which capture the notions of correct protocols, and secrecy of data. The methodology can be used to prove that protocols satisfy these properties. Based on the model they have developed a tool set called Scyther that can automatically find attacks on security protocols or prove their correctness. In case studies they show the application of the methodology as well as the effectiveness of the analysis tool. The methodology’s strong mathematical basis, the strong separation of concerns in the model, and the accompanying tool set make it ideally suited both for researchers and graduate students of information security or formal methods and for advanced professionals designing critical security protocols.
