Non-malleable codes were introduced by Dziembowski, Pietrzak, and Wichs (JACM 2018) as a generalization of standard error correcting codes to handle severe forms of tampering on codewords. This notion...

Motivated by the problem of how to communicate over a public channel with an active adversary, Dodis and Wichs (STOC’09) introduced the notion of a non-malleable extractor. A non-malleable extractor n...

We study the question of basing symmetric key cryptography on weak secrets. In this setting, Alice
and Bob share an n-bit secretW, which might not be uniformly random, but the adversary has at least
