The information flow property of Non-Interference was recently relaxed into Abstract NonInterference (ANI), a weakened version where attackers can only observe properties of data,...
We study a clean machine model for external memory and stream processing. We show that the number of scans of the external data induces a strict hierarchy (as long as work space is...
We show the following results regarding complete sets. • NP-complete sets and PSPACE-complete sets are many-one autoreducible. • Complete sets of any level of PH, MODPH, or th...
We first consider infinite two-player games on pushdown graphs. In previous work, Cachat, Duparc and Thomas [4] have presented a winning decidable condition that is Σ3-complete ...
We consider the issues of implicitness and cache-obliviousness in the classical dictionary problem for n distinct keys over an unbounded and ordered universe. One finding in this ...
