Net-centric information spaces have become a necessary concept to support information exchange for tactical warfighting missions using a publish-subscribe-query paradigm. To support dynamic, mission-critical and time-critical operations, information spaces require quality of service (QoS)-enabled dissemination (QED) of information. This paper describes the(More)
Publish-subscribe-based Information Management (IM) services provide a key enabling technology for net-centric operations. This paper describes technology for Quality of Service (QoS) and Internet-Protocol-based Airborne Networking features for IM services. Enhancing IM services with airborne networking features improves effectiveness in combined tactical(More)
Service-Oriented Architecture (SOA) is becoming a major paradigm for distributed application development in the recent explosion of Internet services and cloud computing. However, SOA introduces new security challenges not present in the single-hop client-server architectures due to the involvement of multiple service providers in a service request. The(More)
Transport Layer Security (TLS) and its precursor Secure Sockets Layer (SSL) are the most widely deployed protocol to establish secure communication over insecure Internet Protocol (IP) networks. Providing a secure session layer on top of TCP, TLS is frequently the first defense layer encountered by adversaries who try to cause loss of confidentiality by(More)
Mobile peer-to-peer networks of aerial vehicles (AVs) have become significant in collaborative tasks including military missions and search and rescue operations. However, the nature of the communication between the nodes in these networks makes the disseminated data prone to interception by malicious parties, which could cause serious harm for the(More)
An increasing number of military systems are being developed using service orientation. Some of the features that make service orientation appealing, like loose coupling, dynamism and composition-oriented system construction, make securing service-based systems more complicated. We have been developing technologies for Advanced Protected Services (APS) to(More)
Service-oriented architecture (SOA) middleware has emerged as a powerful and popular distributed computing paradigm due to its high-level abstractions for composing systems and encapsulating platform-level details and complexities. Control of some details encapsulated by SOA middleware is necessary, however, to provide managed quality-of-service (QoS) for(More)
This paper presents a policy-driven approach to quality-of-service (QoS) management that works with existing service-oriented data dissemination middleware, such as the Java Messaging Service (JMS). Our approach includes services that (1) support specifying and enforcing the QoS preferences of individual clients, (2) mediate and aggregate QoS management on(More)
Mobile devices performing mission-critical functions at the tactical edge, such as those employed by first responders, military personnel, and law enforcement, operate in environments that are vastly different from enterprise computing environments. In spite of the differences in resource availability, threat models, vulnerabilities, information formats,(More)
