On the Pseudorandomness of Top-Level Schemes of Block Ciphers
Block ciphers are usually based on one top-level scheme into which we plug “round functions”. To analyze security, it is important to study the intrinsic security provided by t...

A Key Distribution Scheme Preventing Collusion Attacks in Ubiquitous Heterogeneous Sensor Networks
Abstract. Random key pre-distribution schemes are vulnerable to collusion attacks. In this paper, we propose a new key management scheme for ubiquitous heterogeneous sensor network...

Learning a Hidden Matching
We consider the problem of learning a matching (i.e., a graph in which all vertices have degree 0 or 1) in a model where the only allowed operation is to query whether a set of ve...
