The security analysis of real-world protocols involves reduction steps that are conceptually
simple but still have to account for many protocol complications found in standards and …

State-separating proofs (SSP) is a recent methodology for structuring game-based
cryptographic proofs in a modular way, by using algebraic laws to exploit the modular …

Secure Multi-Party Computation (MPC) is an important enabling technology for data privacy
in modern distributed applications. Currently, proof methods for low-level MPC protocols are …

Garbling schemes allow to garble a circuit C and an input x such that C (x) can be computed
while hiding both C and x. In the context of adaptive security, an adversary specifies the …

Machine-checked cryptography aims to reinforce confidence in the primitives and protocols
that underpin all digital security. However, machine-checked proof techniques remain in …

Cryptographic protocols are commonly used to provide security for network traffic and digital
interactions in general. Security means different things in different contexts. The most …

Cryptographers rely on visualization to effectively communicate cryptographic constructions
with one another. Visual frameworks such as constructive cryptography (TOSCA 2011), the …

Garbling schemes allow to garble a circuit $ C $ and an input $ x $ such that $ C (x) $ can be
computed while hiding both $ C $ and $ x $. In the context of adaptive security, an adversary …

Abstract Machine-checked cryptography aims to reinforce confidence in the primitives and
protocols that underpin all digital security. However, machine-checked proof techniques …

The sumcheck protocol is an interactive proof which is widely used in computational
complexity and cryptography. First introduced in 1992, the proofs of its security properties …
