Efficient Fail-Stop Signatures from the Factoring Assumption

Khaled Ouafi, Atefeh Mashatan

In this paper, we revisit the construction of fail-stop signatures from the factoring assumption. These signatures were originally proposed to provide information-theoretic-based security against forgeries. In contrast to classical signature schemes, in wh ...

OREN: Optimal Revocations in Ephemeral Networks

Jean-Pierre Hubaux, Maxime Raya, Igor Bilogrevic

Public-key certificates allow a multitude of entities to securely exchange and verify the authenticity of data. However, the ability to effectively revoke compromised or untrustworthy certificates is of great importance when coping with misbehavior. In thi ...

Secret message capacity of erasure broadcast channels with feedback

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

We characterize the secret message capacity of a wiretapped erasure channel where causal channel state informa- tion of the honest nodes is publicly available. In doing so, we establish an intimate connection between message secrecy and secret key generati ...

Pollution Attack Defense for Coding Based Sensor Storage

László Czap, Levente Buttyan

We present a novel information theoretic approach to make network coding based storage secure against pollution attacks in sensor networks. The approach is based on a new decoding algorithm which makes it possible to ﬁnd adversarial blocks using one more e ...

Spatial Awareness in Full-Body Immersive Interactions: Where Do We Stand?

Ronan Boulic, Manuel Peinado, Daniel Raunhardt, Damien Maupu

We are interested in developing real-time applications such as games or virtual prototyping that take advantage of the user full-body input to control a wide range of entities, from a self-similar avatar to any type of animated characters, including virtua ...

A Mobile World of Security

Rüdiger Urbanke, Christina Fragouli, Panagiotis Papadimitratos, Christine Neuberg

Mobile users are increasing fast in numbers, new types of services and applications become available, and new mobile systems (e.g., for intelligent transportation) emerge. Meanwhile, the need for securing communication in such large scale, highly dynamic s ...

The Extended Access Control for Machine Readable Travel Documents

Rafik Chaabouni

Machine Readable travel documents have been rapidly put in place since 2004. The initial standard was made by the ICAO and it has been quickly followed by the Extended Access Control (EAC). In this presentation, we discuss about the evolution of these stan ...

Practical unconditionally secure two-channel message authentication

Atefeh Mashatan

We investigate unconditional security for message authentication protocols that are designed using two-channel cryptography. (Two-channel cryptography employs a broadband, insecure wireless channel and an authenticated, narrow-band manual channel at the sa ...

Interpreting Hash Function Security Proofs

Juraj Sarinay

We provide a concrete security treatment of several "provably secure" hash functions. Interpreting arguments behind MQ-HASH, FSB, SWIFFTX and VSH we identify similar lines of reasoning. We aim to formulate the main security claims in a language closer to t ...

Signatures for Multisource Network Coding

László Czap

We consider the problem of securing inter-ﬂow network coding with multiple sources. We present a practical homomorphic signature scheme that makes possible to verify network coded packets composed of data originating from diﬀerent sources. The multi-source ...
