Gradebadge: Development Of A Cloud-Based Reward Application, Erwin Toni Soekianto Jan 2013

Gradebadge: Development Of A Cloud-Based Reward Application, Erwin Toni Soekianto

Theses Digitization Project

The purpose of this project is to investigate the use of cloud-based services to deliver cutting edge applications. For this purpose, a prototype of a reward application using badges, called Gradebadge, was developed to illustrate and explore this emerging paradigm.


Quantifying Computer Network Security, Ian Burchett Dec 2011

Quantifying Computer Network Security, Ian Burchett

Masters Theses & Specialist Projects

Simplifying network security data to the point that it is readily accessible and usable by a wider audience is increasingly becoming important, as networks become larger and security conditions and threats become more dynamic and complex, requiring a broader and more varied security staff makeup. With the need for a simple metric to quantify the security level on a network, this thesis proposes: simplify a network’s security risk level into a simple metric. Methods for this simplification of an entire network’s security level are conducted on several characteristic networks. Identification of computer network port vulnerabilities from NIST’s Network Vulnerability Database …


Information-Quality Aware Routing In Event-Driven Sensor Networks, Hwee Xian Tan, Mun-Choon Chan, Wendong Xiao, Peng-Yong Kong, Chen-Khong Tham Mar 2010

Information-Quality Aware Routing In Event-Driven Sensor Networks, Hwee Xian Tan, Mun-Choon Chan, Wendong Xiao, Peng-Yong Kong, Chen-Khong Tham

Upon the occurrence of a phenomenon of interest in a wireless sensor network, multiple sensors may be activated, leading to data implosion and redundancy. Data aggregation and/or fusion techniques exploit spatio-temporal correlation among sensory data to reduce traffic load and mitigate congestion. However, this is often at the expense of loss in Information Quality (IQ) of data that is collected at the fusion center. In this work, we address the problem of finding the least-cost routing tree that satisfies a given IQ constraint. We note that the optimal least-cost routing solution is a variation of the classical NP-hard Steiner tree …


Networks - Ii: Overhead Analysis Of Security Implementation Using Ipsec, Muhammad Awais Azam, Zaka -Ul- Mustafa, Usman Tahir, S. M. Ahsan, Muhammad Adnan Naseem, Imran Rashid, Muhammad Adeel Aug 2009

Networks - Ii: Overhead Analysis Of Security Implementation Using Ipsec, Muhammad Awais Azam, Zaka -Ul- Mustafa, Usman Tahir, S. M. Ahsan, Muhammad Adnan Naseem, Imran Rashid, Muhammad Adeel

International Conference on Information and Communication Technologies

Authentication, access control, encryption and auditing make up the essential elements of network security. Researchers have dedicated a large amount of efforts to implement security features that fully incorporate the use of all these elements. Currently, data networks mainly provide authentication and confidentiality services. Confidentiality alone is not able to protect the system, thus, suitable security measures must be taken. However, this security is itself an overhead which must be accounted for. A trade-off must exist between performance and security. This trade-off must be carefully managed so as not to deteriorate the systems being secured. This calls for the true …


Keynote: Emerging Era Of Cooperative Empowerment: Grid, Peer-To-Peer, And Community Computing, Dr. Javed I. Khan Aug 2005

Keynote: Emerging Era Of Cooperative Empowerment: Grid, Peer-To-Peer, And Community Computing, Dr. Javed I. Khan

International Conference on Information and Communication Technologies

In this paper we discuss an emerging trend in high performance computing-the social or community computing. The emergence of screensaver computing, grid computing, peer-to-peer systems, and their demonstrated ability to garner computing power as potent as the supercomputers seems to be auspicious. In this paper we discuss the new phenomenon of community computing-including their potential applications in solving a new set of grand challenge problems. We also discuss the previously uncharted technological challenges architects of these new paradigms are addressing.


Secured Network Model For Management Information System Based On Ip Security (Ipsec) Encryption Using Multilayered Approach Of Network Security, Dr. Amir Hassan Pathan, Muniza Irshad Aug 2005

Secured Network Model For Management Information System Based On Ip Security (Ipsec) Encryption Using Multilayered Approach Of Network Security, Dr. Amir Hassan Pathan, Muniza Irshad

International Conference on Information and Communication Technologies

Secured flow of information through the network and play important role in the management information systems. In this paper I describe Secured Network Model For Corporate & Business Organization In Based On Network Level IP Security (IPSec) Encryption & Its Physical Layout Using Multilayered Approach. I have four important considerations for adoption of secured network model as secured network model for management information system.


A Survey On Intrusion Detection Approaches, A Murali M. Rao Aug 2005

A Survey On Intrusion Detection Approaches, A Murali M. Rao

International Conference on Information and Communication Technologies

Intrusion detection plays one of the key roles in computer security techniques and is one of the prime areas of research. Usages of computer network services are tremendously increasing day by day and at the same time intruders are also playing a major role to deny network services, compromising the crucial services for Email, FTP and Web. Realizing the importance of the problem due to intrusions, many researchers have taken up research in this area and have proposed several solutions. It has come to a stage to take a stock of the research results and project a comprehensive view so …


Multi-Level Modeling Of Software On Hardware In Concurrent Computation, Joann M. Paul, Arne Suppe, Henele I. Adams, Donald E. Thomas Apr 2002

Multi-Level Modeling Of Software On Hardware In Concurrent Computation, Joann M. Paul, Arne Suppe, Henele I. Adams, Donald E. Thomas

Research Collection School Of Computing and Information Systems

The fundamental modeling differences between hardware and software modeling can be thought of as reasoning about connectedness vs. reasoning about interleaved (shared) access to resources. A natural design hierarchy for physical systems is component-based because of the existence of a consistent basis for interconnect between design levels. However, performance modeling and design of concurrent, programmable systems require new ways of thinking about what it means to abstract detail, add detail and partition a model of software executing on hardware. We motivate frequency interleaving (FI) as a common simulation foundation for these systems because it resolves flow and partitioning with software …
