But Why does it Work? A Rational Protocol Design Treatment of Bitcoin
Blockchain Protocols Rational Protocol Design Bitcoin
2018/2/8
An exciting recent line of work has focused on formally investigating the core cryptographic assumptions underlying the security of Bitcoin. In a nutshell, these works conclude that Bitcoin is secure ...

Complex cryptographic protocols are often designed from simple cryptographic primitives, such as signature schemes, encryption schemes, verifiable random functions, and zero-knowledge proofs, by bridg...
Key Exchange with Unilateral Authentication: Composable Security Definition and Modular Protocol Design
key exchange constructive cryptography
2014/3/10
Key exchange with unilateral authentication (short: unilateral key exchange) is an important primitive in practical security protocols; a prime example is the widely deployed TLS protocol, which is us...
Rational Protocol Design: Cryptography Against Incentive-driven Adversaries

2014/3/10
Existing work on “rational cryptographic protocols” treats each party (or coalition of parties) running the protocol as a selfish agent trying to maximize its utility. In this work we propose a fundam...
Signing on Elements in Bilinear Groups for Modular Protocol Design

This paper addresses the construction of signature schemes whose verification keys, messages,
and signatures are group elements and the verification predicate is a conjunction of
pairing product equ...
