A Case Study In Forensic Analysis Of Control, Fred Cohen
Journal of Digital Forensics, Security and Law
This paper describes a case study in which a method for forensic analysis of control was applied to resolve probative technical issues in a legal action. It describes one instance in which the analysis was successfully applied without challenge, addresses the details of most of the different facets of the analysis method, and demonstrates how such analysis provides a systematic approach to using technical methods to address legal issues as a case study.

Extraction Of Electronic Evidence From Voip: Forensic Analysis Of A Virtual Hard Disk Vs Ram, David Irwin, Jill Slay, Arek Dadej, Malcolm Shore
Journal of Digital Forensics, Security and Law
The popularity of Voice over the Internet Protocol (VoIP) is increasing as the cost savings and ease of use is realised by a wide range of home and corporate users. However, the technology is also attractive to criminals. This is because VoIP is a global telephony service, in which it is difficult to verify the user’s identification. The security of placing such calls may also be appealing to criminals, as many implementations use strong encryption to secure both the voice payload as well as to control messages making monitoring such VoIP calls difficult since conventional methods such as wire-tapping is …

Book Review: Ios Forensic Analysis: For Iphone, Ipad And Ipod Touch, Christopher Schulte
Journal of Digital Forensics, Security and Law
As Digital Forensics practitioners, we know that our discipline is constantly evolving. Keeping abreast means we need to continually refine and broaden our knowledge pools through experience, education, research, peer exchange, and more. Mobile device forensics can be especially dynamic and challenging. With multiple standards in place at the hardware, operating system, and user interface levels, it can be daunting to preserve, analyze, search and report on these tiny yet ubiquitous hand-held computers. Apple Computer’s line of mobile products (iOS devices - iPhone, iPad, iPod Touch) is no exception to this rule.

Inheritance powder is the name that was given to poisons, especially arsenic, that were commonly used in the 17th and early 18th centuries to hasten the death of the elderly. For most of the 17th century, arsenic was deadly but undetectable, making it nearly impossible to prove that someone had been poisoned. The first arsenic test produced a gas—hardly something that a scientist could show to a judge. Faced with a growing epidemic of poisonings, doctors and chemists spent decades searching for something better
Technology Corner: Brute Force Password Generation -- Basic Iterative And Recursive Algorithms, Nick V. Flor, Haile Shannon
Technology Corner: Brute Force Password Generation -- Basic Iterative And Recursive Algorithms, Nick V. Flor, Haile Shannon
Journal of Digital Forensics, Security and Law
Most information systems are secured at minimum by some form of password protection. For various reasons a password may be unavailable, requiring some form of password recovery procedure. One such procedure is software-based automated password recovery, where a program attempts to log into a system by repeatedly trying different password combinations. At the core of such software is a password generator. This article describes the basic iterative and recursive algorithms for generating all possible passwords of a given length, which is commonly referred to as brute-force password generation. The paper ends with a discussion of alternative password recovery procedures one …
Identity-Based Strong Designated Verifier Signature Revisited, Qiong Huang, Guomin Yang, Duncan S. Wong, Willy Susilo
Identity-Based Strong Designated Verifier Signature Revisited, Qiong Huang, Guomin Yang, Duncan S. Wong, Willy Susilo
Research Collection School Of Computing and Information Systems
Designated verifier signature (DVS) allows the signer to persuade a verifier the validity of a statement but prevent the verifier from transferring the conviction. Strong designated verifier signature (SDVS) is a variant of DVS, which only allows the verifier to privately check the validity of the signer’s signature. In this work we observe that the unforgeability model considered in the existing identity-based SDVS schemes is not strong enough to capture practical attacks, and propose to consider another model which is shown to be strictly stronger than the old one. We then propose a new efficient construction of identity-based SDVS scheme, …

Since the first handheld cellular phone was introduced in 1970s, the mobile phone has changed significantly both in terms of popularity and functionality. With more than 4.6 billion subscribers around the world, it has become a ubiquitous device in our daily life. Apart from the traditional telephony and text messaging services, people are enjoying a much wider range of mobile services over a variety of network connections in the form of mobile applications. Although a number of security mechanisms such as authentication, antivirus, and firewall applications are available, it is still difficult to keep up with various mobile threats (i.e. …
Security Risk Management: A Psychometric Map Of Expert Knowledge Structure, David Brooks
Security Risk Management: A Psychometric Map Of Expert Knowledge Structure, David Brooks
Research outputs 2011
The security industry operates within a diverse and multi-disciplined knowledge base, with risk management as a fundamental knowledge domain within security to mitigate its risks. Nevertheless, there has been limited research in understanding and mapping security expert knowledge structures within security risk management to consider if parts of security risk management are unique from more general risk management. This interpretive study applied a technique of multidimensional scaling (MDS) to develop and present a psychometric map within the knowledge domain of security risk management, validated with expert interviews. The psychometric MDS security risk management concept map presented the expert knowledge structure …
Analysis Of Data Remaining On Second Hand Adsl Routers, Patryk Szewczyk
Analysis Of Data Remaining On Second Hand Adsl Routers, Patryk Szewczyk
Research outputs 2011
In theory, an ADSL router can provide an additional layer of security to a wired and wireless network through; access control, wireless encryption, firewall rule sets, and network event logging. An ADSL router may also contain the users’ usage habits and broadband account credentials. However, end-users may be unaware of the intricacies of the security measures available and the potentially confidential information stored on their device. As a result a second hand ADSL router may contain a wealth of user-specific information if not wiped and disposed of in a secure manner. This paper shows the data that was acquired from …
Efficient Strong Designated Verifier Signature Schemes Without Random Oracle Or With Non-Delegatability, Qiong Huang, Guomin Yang, Duncan S. Wong, Willy Susilo
Efficient Strong Designated Verifier Signature Schemes Without Random Oracle Or With Non-Delegatability, Qiong Huang, Guomin Yang, Duncan S. Wong, Willy Susilo
Research Collection School Of Computing and Information Systems
Designated verifier signature (DVS) allows a signer to convince a designated verifier that a signature is generated by the signer without letting the verifier transfer the conviction to others, while the public can still tell that the signature must be generated by one of them. Strong DVS (SDVS) strengthens the latter part by restricting the public from telling whether the signature is generated by one of them or by someone else. In this paper, we propose two new SDVS schemes. Compared with existing SDVS schemes, the first new scheme has almost the same signature size and meanwhile, is proven secure …

Lightweight Delegated Subset Test With Privacy Protection, Xuhua Zhou, Xuhua Ding, Kefei Chen
Research Collection School Of Computing and Information Systems
Delegated subset tests are mandatory in many applications, such as content-based networks and outsourced text retrieval, where an untrusted server evaluates the degree of matching between two data sets. We design a novel scheme to protect the privacy of the data sets in comparison against the untrusted server, with half of the computation cost and half of the ciphertext size of existing solutions based on predicate only encryption supporting inner product.
