We provide attacks and analysis that capture a tradeoff, in the ideal-permutation model, between the speed of a permutation-based hash function and its potential security. For coll...

Standard security notions for encryption schemes do not guarantee any security if the encrypted messages depend on the secret key. Yet it is exactly the stronger notion of security...

Predicate encryption is a new paradigm for public-key encryption generalizing, among other things, identity-based encryption. In a predicate encryption scheme, secret keys corresp...
