Specifying electronic voting protocols in typed MSR

Abstract

Electronic voting, as well as other privacy-preserving protocols, use special cryptographic primitives and techniques that are not widely used in other types of protocols, e.g. in authentication protocols. These include blind signatures, commitments, zero-knowledge proofs, mixes and homomorphic encryption. Furthermore, typical formalizations of the Dolev-Yao intruder's capabilities do not take into account these primitives and techniques, nor do they consider some types of attacks that e-voting as well as other types of protocols are designed to protect against, such as privacy attacks due to undesired linkability of protocol executions. This work aims to extend Typed MSR so that it is able to support the specification of privacy-preserving protocols, as well as the capabilities of a Dolev-Yao intruder designed to attack such protocols.
