Matryoshka: Hiding Secret Communication in Plain Sight

Christina Fragouli, Iris Safaka

We want to enable a pair of communicating users to exchange secret messages while hiding the fact that secret communication is taking place. We propose a linguistic steganography approach, where each human message is hidden in another human-like message. A ...

Riffle: An Efficient Communication System With Strong Anonymity

Bryan Alexander Ford, David Lazar

Existing anonymity systems sacrifice anonymity for efficient communication or vice-versa. Onion-routing achieves low latency, high bandwidth, and scalable anonymous communication, but is susceptible to traffic analysis attacks. Designs based on DC-Nets, on ...

Metadata Protection Considerations for TLS Present and Future

Bryan Alexander Ford

TLS 1.3 takes important steps to improve both performance and security, so far offers little protection against traffic analysis or fingerprinting using unencrypted metadata or other side-channels such as transmission lengths and timings. This paper explor ...

Towards Unconditional Tor-Like Anonymity

Christina Fragouli, László Czap, Iris Safaka

We design and evaluate a traffic anonymization protocol for wireless networks, aiming to protect against computationally powerful adversaries. Our protocol builds on recent key-generation techniques, that leverage intrinsic properties of the wireless toget ...

Seeking Anonymity in an Internet Panopticon

Bryan Alexander Ford

Internet, users often need to assume, by default, that their every statement or action online is monitored and tracked. The Dissent project at Yale University takes a collective approach to online anonymity, based on different algorithmic foundations from ...

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 ...

Privacy of Community Pseudonyms in Wireless Peer-to-Peer Networks

Jean-Pierre Hubaux, Murtuza Jadliwala, Julien Freudiger, Valtteri Niemi

Wireless networks offer novel means to enhance social interactions. In particular, peer-to-peer wireless communications enable direct and real-time interaction with nearby devices and communities and could extend current online social networks by providing ...

Distributed Authentication in Anonymous Mobile Communities

Hamza Harkous

With the recent boom in smartphones technology, online social networks are going mobile. This trend urged phone manufacturers and social networking companies to seek novel business strategies to monetize from these new "gateways" and to give the users ...

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 ...

Dissent in Numbers: Making Strong Anonymity Scale

Bryan Alexander Ford, Henry Nathaniel Corrigan-Gibbs

Current anonymous communication systems make a trade-off between weak anonymity among many nodes, via onion routing, and strong anonymity among few nodes, via DC-nets. We develop novel techniques in Dissent, a practical group anonymity system, to increase ...
