Keeping Authorities “Honest or Bust” with Decentralized Witness Cosigning

Bryan Alexander Ford, Linus Gasser, Philipp Svetolik Jovanovic, Nicolas Gailly, Ismail Khoffi

Abstract—The secret keys of critical network authorities – such as time, name, certificate, and software update services – represent high-value targets for hackers, criminals, and spy agencies wishing to use these keys secretly to compromise other hosts. T ...

Method for privacy-preserving medical risk test

Jean-Pierre Hubaux, Amalio Telenti, Erman Ayday, Jean Louis Raisaro

A privacy-preserving method for performing a disease susceptibility test on a patient, said method comprising: (I) performing homomorphic computations, (J) obtaining a test result which is partly decrypted with a first part (prk1 resp. prk2) of a private k ...

Privacy-Preserving Photo Sharing based on a Public Key Infrastructure

Touradj Ebrahimi, Lin Yuan, David Mc Nally

A significant number of pictures are posted to social media sites or exchanged through instant messaging and cloud-based sharing services. Most social media services offer a range of access control mechanisms to protect users privacy. As it is not in the b ...

An FPGA-Based 4 Mbps Secret Key Distillation Engine for Quantum Key Distribution Systems

Andreas Peter Burg, Jeremy Hugues-Felix Constantin, Nicholas Alexander Preyss, Pascal Junod

Quantum key distribution (QKD) enables provably secure communication between two parties over an optical ber that arguably withstands any form of attack. Besides the need for a suitable physical signalling scheme and the corresponding devices, QKD also req ...

Method and device for proving his identity

Serge Vaudenay, Ioana Cristina Carlson

The invention is related to a method allowing a prover holding a secret key (x) to prove its identity to a verifier and to prove to this verifier that he is within a predetermined distance of this verifier, said method comprising an initialization phase du ...

Optimal polynomial blow up range for critical wave maps

Can Gao

We prove that the critical Wave Maps equation with target

S^2

and origin ℝ

^{2+1}

admits energy class blow up solutions of the form [ u(t, r) = Q(\lambda(t)r) + \epsilon(t, r) ] where

Q:ℝ²\rightarrow S^2

is the ground state harmonic map and $\lambda ...

Efficient Non-malleable Codes and Key-Derivation for Poly-size Tampering Circuits

Sebastian Faust

Non-malleable codes, defined by Dziembowski, Pietrzak and Wichs (ICS ’10), provide roughly the following guarantee: if a codeword c encoding some message x is tampered to c' = f(c) such that c c, then the tampered message x contained in c reveals no inf ...

Secure Wireless Communications via Cooperative Transmitting

Ninoslav Marina

Information-theoretic secrecy is combined with cryptographic secrecy to create a secret-key exchange protocol for wireless networks. A network of transmitters, which already have cryptographically secured channels between them, cooperate to exchange a secr ...

Triangle Network Secrecy

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

We characterize the secret message capacity of the triangle network, that consists of a source, a relay and a destination connected through orthogonal erasure channels. A passive eavesdropper, Eve, wiretaps any one of the three channels. The source and the ...
