Financial Cryptography Workshops

In electronic voting, we say that a protocol has cast-as-intended verifiability if the contents of each encrypted vote can be audited in order to ensure that they match the voter’s selections. It is traditionally thought that this verification can

VOTE-ID

One way to build secure electronic voting systems is to use Mix-Nets, which break any correlation between voters and their votes. One of the characteristics of Mix-Net-based eVoting is that ballots are usually decrypted individually and, as a consequ

Public Key Cryptography

Groth-Sahai proofs are efficient non-interactive zero-knowledge proofs that have found widespread use in pairing-based cryptography. We propose efficiency improvements of Groth-Sahai proofs in the SXDH setting, which is the one that yields the most e

An attribute-based signature with respect to a signing policy, chosen ad-hoc by the signer, convinces the verifier that the signer holds a subset of attributes satisfying that signing policy. The verifier must obtain no other information about the id
