Making The Key Agreement Protocol In Mobile Ad Hoc Network More Efficient, Gang Yao, Kui Ren, Feng Bao, Robert H. Deng, Dengguo Feng
Research Collection School Of Computing and Information Systems
Mobile ad hoc networks offer convenient infrastructureless communications over the shared wireless channel. However, the nature of mobile ad hoc networks makes them vulnerable to security attacks, such as passive eavesdropping over the wireless channel and denial of service attacks by malicious nodes. To ensure the security, several cryptography protocols are implemented. Due to the resource scarcity in mobile ad hoc networks, the protocols must be communication efficient and need as less computational power as possible. Broadcast communication is an important operation for many application in mobile ad hoc networks. To securely broadcast a message, all the members in the …

The expanding availability of health information in an electronic format is strategic for industry-wide efforts to improve the quality and reduce the cnst of health care. The implementation of electronic medical record systems has been hindered by inadequate security provisions. This paper describes the use of frust negotiation as a framework for providing authentication and access control services in healthcare information systems. nust negotiation enables two parties with no pre-existing relationship to establish the trust necessary to perform sensitive transactions via the mutual disclosure of attributes contained within digital credentials. An extension of this system, surrogate irusf negoikiion is introduced …

Application adaptive bandwidth management is a strategy for ensuring secure and reliable network operation in the presence of undesirable applications competing for a network’s crucial bandwidth, covert channels of communication via non-standard traffic on well-known ports, and coordinated Denial of Service attacks. The study undertaken here explored the classification, analysis and management of the network traffic on the basis of ports and protocols used, type of applications, traffic direction and flow rates on the East Tennessee State University’s campus-wide network. Bandwidth measurements over a nine-month period indicated bandwidth abuse of less than 0.0001% of total network bandwidth. The conclusion suggests …

We consider the problem of intrusion analysis and present the Kerf toolkit, whose purpose is to provide an efficient and flexible infrastructure for the analysis of attacks. The Kerf toolkit includes a mechanism for securely recording host and network logging information for a network of workstations, a domain-specific language for querying this stored data, and an interface for viewing the results of such a query, providing feedback on these results, and generating new queries in an iterative fashion. We describe the architecture of Kerf in detail, present examples to demonstrate the power of our query language, and discuss the performance …
Protecting Sensitive Credential Content During Trust Negotiation, Ryan D. Jarvis
Protecting Sensitive Credential Content During Trust Negotiation, Ryan D. Jarvis
Theses and Dissertations
Keeping sensitive information private in a public world is a common concern to users of digital credentials. A digital credential may contain sensitive attributes certifying characteristics about its owner. X.509v3, the most widely used certificate standard, includes support for certificate extensions that make it possible to bind multiple attributes to a public key contained in the certificate. This feature, although convenient, potentially exploits the certificate holder's private information contained in the certificate. There are currently no privacy considerations in place to protect the disclosure of attributes in a certificate. This thesis focuses on protecting sensitive credential content during trust negotiation …

A Case Study In The Security Of Network-Enabled Devices, Simeon Xenitellis, Craig Valli
Research outputs pre 2011
It is becoming increasingly common for appliances and other electronic devices to be network-enabled for usability and automation purposes. There have been fears that malicious users can control such devices remotely. Since the installation base of such network-enabled household devices is still relatively small, we examine the types of vulnerabilities that another such applicance has, the network-enabled printer, which is commonly found in the education and business sector. In this paper we analyse the source of the vulnerabilities and present detailed threat scenarios. In addition, we examine four organisations in Australia and Europe. Based on the results of the case …
