SCoT: A secure content-oriented transport

Secure SCTP - A Versatile Secure Transport Protocol

The Stream Control Transmission Protocol (SCTP) is a new general purpose transport protocol defined by the IETF. Originally intended for the transport of voice signaling data (SS7) over IP networks, SCTP together with newly defined extensions is increasingly considered for other application scenarios as well. These require strong security solutions to authenticate the communication partners and...

SCoT: A Spoken Conversational Tutor

We describe SCoT, a Spoken Conversational Tutor, which has been implemented in order to investigate the advantages of natural language in tutoring, especially spoken language. SCoT uses a generic architecture for conversational intelligence which has capabilities such as turn management and coordination of multi-modal input and output. SCoT also includes a set of domain independent tutorial rec...

A Multilevel Secure Object- Oriented Data Model

Recently, several security models have appeared in the literature dealing with mandatory access controls in object-oriented databases. While some of them are of considerable interest and merit (see the later section " Review of relevant research " for a discussion), they seem to lack intuitive appeal because they do not appear to model security in a way that takes full advantage of the object-o...

SODA: A secure object-oriented database system

This paper describes a security model for object-oriented systems. The model supports a flexible data classification policy based on inheritance. The classification policy allows for a smooth transition bctwccn rigid classification rules and unlimited polyinstantiation. The security model treats the data model as well as the computational model of object-oriented systems allowing more flexibili...
