Securing Broadcast Against Dishonest Receivers

Christina Fragouli, Suhas Diggavi, László Czap, Vinod Malathidevi Prabhakaran

Consider a sender, Alice, who wants to transmit private messages to two receivers, Bob and Calvin, using unreliable wireless broadcast transmissions and short public feedback from Bob and Calvin. In [1], we assumed that Bob and Calvin provide honest feedba ...

A Distributed Polling with Probabilistic Privacy

Rachid Guerraoui, Florian Huc, Yahya Benkaouz

In this paper, we present PDP, a distributed polling protocol that enables a set of participants to gather their opinion on a common interest without revealing their point of view. PDP does not rely on any centralized authority or on heavyweight cryptograp ...

Scalable and Secure Polling in Dynamic Distributed Networks

Rachid Guerraoui, Anne-Marie Kermarrec, Hamza Harkous, Florian Huc

We consider the problem of securely conducting a poll in synchronous dynamic networks equipped with a Public Key Infrastructure (PKI). Whereas previous distributed solutions had a communication cost of O(n^2) in an n nodes system, we present SPP (Secure an ...

Quantification of "Fuzzy" Chemical Concepts: A Computational Perspective

Matthew Wodrich, Jérôme Florian Gonthier

Chemists recurrently utilize "fuzzy'' chemical concepts (e.g. atomic charges, the chemical bond, strain, aromaticity, branching, etc.), which lack unique quantitative assessments but, nonetheless, are frequently employed as tools for understanding the intr ...

Unconditionally-Secure Robust Secret Sharing with Compact Shares

Alfonso Bolívar Cevallos Manzano

We consider the problem of reconstructing a shared secret in the presence of faulty shares, with unconditional security. We require that any t shares give no information on the shared secret, and reconstruction is possible even if up to t out of the n shar ...

A Non-interactive Range Proof with Constant Communication

Rafik Chaabouni, Helger Lipmaa

In a range proof, the prover convinces the verifier in zero-knowledge that he has encrypted or committed to a value a ∈ [0,H] where H is a public constant. Most of the previous non-interactive range proofs have been proven secure in the random oracle model ...

Broadcasting Private Messages Securely

Christina Fragouli, Suhas Diggavi, László Czap, Vinod Malathidevi Prabhakaran

Consider a source, Alice, broadcasting private messages to multiple receivers through a broadcast erasure channel; users send back to Alice public feedback that she causally uses to decide the coding strategy for her following transmissions. Recently, the ...

Multi-terminal Secrecy in a Linear Non-coherent Packetized Networks

Christina Fragouli, Mahdi Jafari Siavoshani

We consider a group of m+1 trusted nodes that aim to create a shared secret key K over a network in the presence of a passive eavesdropper, Eve. We assume a linear non-coherent network coding broadcast channel (over a finite field F_q ) from one of the hon ...
