Non-malleable Reductions and Applications

Non-malleable codes, introduced by Dziembowski, Pietrzak and Wichs [DPW10], provide a useful message integrity guarantee in situations where traditional error-correction (and even error-detection) is impossible; for example, when the attacker can completel ...

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 ...

Deniable RSA Signature: The Raise and Fall of Ali Baba

Serge Vaudenay

The 40 thieves realize that the fortune in their cave is vanishing. A rumor says that Ali Baba has been granted access (in the form of a certificate) to the cave but they need evidence to get justice from the Caliph. On the other hand, Ali Baba wants to be ...

On Tamper-Resistance from a Theoretical Viewpoint: The Power of Seals

Serge Vaudenay

Tamper-proof devices are pretty powerful. They can be used to have better security in applications. In this work we observe that they can also be maliciously used in order to defeat some common privacy protection mechanisms. We propose the theoretical mode ...
