Most of the proposed algorithms in ad hoc networks assume homogeneous nodes with similar transmission range and capabilities. However, in heterogeneous ad hoc network, it is not ne...
The use of policy-based mechanisms significantly reduces the complexity associated with applicational development and operation. In particular, history-based policies allow the s...
Abstract. Todays data stream management systems (DSMSs) lack security functionality. Based on adversary scenarios we show how a DSMS architecture can be protected. We sketch a gene...
When a private relational table is published using views, secrecy or privacy may be violated. This paper uses a formally-defined notion of k-anonymity to measure disclosure by vi...
Abstract. It is almost a folklore-knowledge that hash-based time-stamping schemes are secure if the underlying hash function is collisionresistant but still no rigorous proofs have...
