Trace equivalence decision: negative tests and non-determinism
We consider security properties of cryptographic protocols that can be modeled using the notion of trace equivalence. The notion of equivalence is crucial when specifying privacy-...

Secrecy for bounded security protocols with freshness check is NEXPTIME-complete
The secrecy problem for security protocols is the problem to decide whether or not a given security protocol has leaky runs. In this paper, the (initial) secrecy problem for bound...

Testing Disjointness of Private Datasets
Two parties, say Alice and Bob, possess two sets of elements that belong to a universe of possible values and wish to test whether these sets are disjoint or not. In this paper we ...

A New Sampling Protocol and Applications to Basing Cryptographic Primitives on the Hardness of NP
We investigate the question of what languages can be decided efficiently with the help of a recursive collisionfinding oracle. Such an oracle can be used to break collisionresistan...

Rigid tree automata and applications
We introduce the class of Rigid Tree Automata (RTA), an extension of standard bottom-up automata on ranked trees with distinguished states called rigid. Rigid states define a res...
