Apparaît dans la collection : 2016 - T1 - WS5 - Secrecy and privacy theme

Over the last few decades, the information theory and the cryptography communities have often studied related security problems. However, they have more than often adopted very different approaches and techniques. The main purpose of this talk is to contribute to bridging this gap, by providing a cryptographic viewpoint on some security problems considered in the information-theory and physical-layer communities. The hope is to convey how to cryptographic approach (both on security metrics and proofs) can be beneficial to information theorists, but also, conversely, how information-theoretic insights can be helpful to cryptographers. I will start this talk with the classical wiretap setting, and then hopefully move on to other topics. (The talk is partially based on joint works with Mihir Bellare and Alexander Vardy. )
