Makowskyvent data, generated by low capability sensor devices, to more capable processing points and vice versa, needs to be addressed for the success of the ECA paradigm in this environment. The problem becomes interesting because strong cryptographic techniques for achieving integrity impose unacceptable

Ideally, using the defined mappings, one would be able to issue a single query that will be rewritten automatically to all the databases, instead of manually writing a query to each database. In a centrally mediated architecture a query is written in terms of a global schema or ontology that integ

To quantitatively assess the security of networked systems, one must first understand which and how vulnerabilities can be combined for an attack. Such an understanding becomes possible with recent advan

Since the users may not be able to adequately protect their cryptographic credentials, our service leverages some better protected servers to help fulfill such authentication needs. Compared with previous proposals, our service has
