This paper addresses the problem of de ning views that span several objectbases. Views are expressed in terms of an object algebra. We are interested in the degrees of coupling an...
We present Drac, a system designed to provide anonymity and unobservability for real-time instant messaging and voice-over-IP communications against a global passive adversary. The...
This paper considers enumeration of substring equivalence classes introduced by Blumer et al. [1]. They used the equivalence classes to define an index structure called compact dir...
In this paper we summarize recent developments in compact dynamical modeling for both linear and nonlinear systems arising in analog applications. These techniques include methods...
A new remote password authentication scheme based on IC cards is proposed in this paper. By using the scheme, a remote password can be authenticated without either a password file...
