The Layered Games Framework for Specifications and Analysis of Security Protocols
Eprint
https://eprint.iacr.org/2006/398
Amir Herzberg Igal Yoffe
We establish rigorous foundations to the use of modular, layered design for building complex distributed systems. Layering is key to the design of the Internet and other distributed systems, hence such solid, theoretical...

The Delivery and Evidences Layer
Eprint
https://eprint.iacr.org/2007/139
Amir Herzberg Igal Yoffe
Evidences of delivery are essential for resolving (and avoiding) disputes on delivery of messages, in classical as well as electronic commerce. We present the first rigorous specifications and provably-secure implementation,...

Provable Security for PKI Schemes
Eprint
https://eprint.iacr.org/2019/807
Hemi Leibowitz Amir Herzberg Ewa Syta
In this work we apply the systematic approach of game-based security specifications and proofs by reductions, to the design and evaluation of public key infrastructure (PKI) schemes. The importance of rigorous definitions and...

ROYALE: A Framework for Universally Composable Card Games with Financial Rewards and Penalties Enforcement
Eprint
https://eprint.iacr.org/2018/157
Bernardo David Rafael Dowsley Mario Larangeira
While many tailor made card game protocols are known, the vast majority of those suffer from three main issues: lack of mechanisms for distributing financial rewards and punishing cheaters, lack of composability guarantees and...

Folklore, Practice and Theory of Robust Combiners
Eprint
https://eprint.iacr.org/2002/135
Amir Herzberg
Cryptographic schemes are often designed as a combination of multiple component cryptographic modules. Such a combiner design is {\em robust} for a (security) specification if it meets the specification, provided that a...

Towards Provably-Secure Timed E-Commerce: The Trusted Delivery Layer
Eprint
https://eprint.iacr.org/2002/084
Amir Herzberg
Certified exchange of messages is an essential mechanism for e-commerce; the timing aspects (timeouts and timestamps) are very important for practical applications. However existing formal methods for security analysis assume...
