With the increasing threat of cyber and other attacks on critical infrastructure, federal governments throughout the world have been organizing industry to share information on possible threats. In Australia the Office of the Attorney General has formed ...

Early works on Private Information Retrieval (PIR) focused on minimizing the necessary communication overhead. They seemed to achieve this goal but at the expense of query response time. To mitigate this weakness, protocols with secure coprocessors were ...

Digital forensics investigations aim to find evidence that helps confirm or disprove a hypothesis about an alleged computer-based crime. However, the ease with which computer-literate criminals can falsify computer event logs makes the prosecutor's job ...

Over the last decade spam has become a serious problem to email-users all over the world. Most of the daily email-traffic consists of this unwanted spam. There are various methods that have been proposed to fight spam, from IP-based blocking to ...

UCON_ABC is an emerging access control framework that lacks an administration model. In this paper we define the problem of administration and propose a novel administrative model. At the core of this model is the concept of attribute, which is also the ...

Abuse of free Internet resources and services from false account creation, to spam, to identity theft, excessive bandwidth usage, or even vote stuffing online polls is a big problem. The Completely Automatic Public Turing Test to tell Computers and ...

Understanding the complex dynamic and uncertain characteristics of organisational employees who perform authorised or unauthorised information security activities is deemed to be a very important and challenging task. This paper presents a conceptual ...

We consider a new form of authenticated key exchange which we call multi-factor password-authenticated key exchange, where session establishment depends on successful authentication of multiple short secrets that are complementary in nature, such as a ...

To date, most applications of algebraic analysis and attacks on stream ciphers are on those based on linear feedback shift registers (LFSRs). In this paper, we extend algebraic analysis to non-LFSR based stream ciphers. Specifically, we perform an ...

We show how to construct a certificateless key agreement protocol from the certificateless key encapsulation mechanism introduced by Lippold et al. (2009a) in ICISC 2009 using the Boyd et al. (2008) protocol from ACISP 2008. We introduce the Canetti-...

We develop a word combinatorial approach to multi-collisions in generalized iterated hash functions. The work rests on the notable discoveries of A. Joux and on generalizations provided by M. Nandi and D. Stinson as well as J. Hoch and A. Shamir. New ...
