The theory of reactive systems, introduced by Leifer and Milner and previously extended by the authors, allows the derivation of well-behaved labelled transition systems (LTS) for...
In this paper we identify context-free grammars as coalgebras. To obtain the associated context-free languages (consisting of only finite-length strings) we introduce a general a...
We introduce a new cryptographic primitive, called insubvertible encryption, that produces ciphertexts which can be randomized without the need of any key material. Unlike plain u...

We introduce the notion of sanitizable signatures that offer many attractive security features for certain current and emerging applications. A sanitizable signature allows author...

We give a drawing of Kn in three dimensions in which vertices are placed at integer grid points and edges are drawn crossing-free with at most one bend per edge in a volume bounde...
