Distributed Public-Key Cryptography from Weak Secrets
Abstract.We introduce the notion of distributed password-based publickey cryptography, where a virtual high-entropy private key is implicitly dened as a concatenation of low-entrop...

Non-malleable extractors and symmetric key cryptography from weak secrets
We study the question of basing symmetric key cryptography on weak secrets. In this setting, Alice and Bob share an n-bit secret W, which might not be uniformly random, but the ad...

Cryptography from Sunspots: How to Use an Imperfect Reference String
The Common Reference String (CRS) model equips all protocol participants with a common string that is sampled from a pre-specified distribution, say the uniform distribution. Thi...
