Verifiable Elections with Commitment Consistent Encryption - A Primer

نویسنده

  • Olivier Pereira
چکیده

This note provides an introduction to the PPATS Commitment Consistent Encryption (CCE) scheme proposed by Cuvelier, Pereira and Peters [7] and its use in the design of end-to-end verifiable elections with a perfectly private audit trail. These elections can be verified using audit data that will never leak any information about the vote, even if all the private keys of the elections are compromised, or if the cryptographic assumptions are broken.

Election Verifiability or Ballot Privacy: Do We Need to Choose?

We propose a new encryption primitive, commitment consistent encryption (CCE), and instances of this primitive that enable building the first universally verifiable voting schemes with a perfectly private audit trail (PPAT) and practical complexity. That is: – the audit trail that is published for verifying elections guarantees everlasting privacy, and – the computational load required from the...

Secret, verifiable auctions from elections

Auctions and elections are seemingly disjoint. Nevertheless, similar cryptographic primitives are used in both domains. For instance, mixnets, homomorphic encryption and trapdoor bit-commitments have been used by state-of-the-art schemes in both domains. These developments have appeared independently. For example, the adoption of mixnets in elections preceded a similar adoption in auctions by o...

Prêt à Voter: All-In-One

A number of voter-verifiable electronic voting schemes have been introduced in the recent decades. These schemes not only provide each voter with a receipt without the threat of coercion and ballot selling, but also the ballot tallying phase can be publicly verified. Furthermore, these schemes are robust because the power of authorities can be threshold distributed. Generally speaking, the homo...

End-to-end veriable voting with Prêt à Voter

Transparent and verifiable elections can be achieved by end-to-end verifiable electronic voting systems. The purpose of such systems is to enable voters to verify the inclusion of their vote in the final tally while keeping the votes secret. Achieving verifiability and secrecy at the same time is hard and this thesis explores the properties of verifiable electronic voting systems and describes ...

SESOS: A Verifiable Searchable Outsourcing Scheme for Ordered Structured Data in Cloud Computing

While cloud computing is growing at a remarkable speed, privacy issues are far from being solved. One way to diminish privacy concerns is to store data on the cloud in encrypted form. However, encryption often hinders useful computation cloud services. A theoretical approach is to employ the so-called fully homomorphic encryption, yet the overhead is so high that it is not considered a viable s...
