Bloom Filters Optimized Wu-Manber For Intrusion Detection, Monther Aldwairi, Koloud Al-Khamaiseh, Fatima Alharbi, Babar Shah

Journal of Digital Forensics, Security and Law

With increasing number and severity of attacks, monitoring ingress and egress network traffic is becoming essential everyday task. Intrusion detection systems are the main tools for capturing and searching network traffic for potential harm. Signature-based intrusion detection systems are the most widely used, and they simply use a pattern matching algorithms to locate attack signatures in intercepted network traffic. Pattern matching algorithms are very expensive in terms of running time and memory usage, leaving intrusion detection systems unable to detect attacks in real-time. We propose a Bloom filters optimized Wu-Manber pattern matching algorithm to speed up intrusion detection. The Bloom …

The Impact Of Md5 File Hash Collisions On Digital Forensic Imaging, Gary C. Kessler

Journal of Digital Forensics, Security and Law

The Message Digest 5 (MD5) hash is commonly used as for integrity verification in the forensic imaging process. The ability to force MD5 hash collisions has been a reality for more than a decade, although there is a general consensus that hash collisions are of minimal impact to the practice of computer forensics. This paper describes an experiment to determine the results of imaging two disks that are identical except for one file, the two versions of which have different content but otherwise occupy the same byte positions on the disk, are the same size, and have the same hash …

Cryptanalysis Of Homophonic Substitution Cipher Using Hidden Markov Models, Guannan Zhong

Master's Projects

We investigate the effectiveness of a Hidden Markov Model (HMM) with random restarts as a mean of breaking a homophonic substitution cipher. Based on extensive experiments, we find that such an HMM-based attack outperforms a previously de- veloped nested hill climb approach, particularly when the ciphertext message is short. We then consider a combination cipher, consisting of a homophonic substitution and a column transposition. We develop and analyze an attack on such a cipher. This attack employs an HMM (with random restarts), together with a hill climb to recover the column permutation. We show that this attack can succeed on …

A Privacy-Preserving Outsourced Functional Computation Framework Across Large-Scale Multiple Encrypted Domains, Ximeng Liu, Baodong Qin, Robert H. Deng, Rongxing Lu, Jianfeng Ma

Research Collection School Of Computing and Information Systems

In this paper, we propose a framework for privacy-preserving outsourced functional computation across large-scale multiple encrypted domains, which we refer to as POFD. With POFD, a user can obtain the output of a function computed over encrypted data from multiple domains while protecting the privacy of the function itself, its input and its output. Specifically, we introduce two notions of POFD, the basic POFD and its enhanced version, in order to tradeoff the levels of privacy protection and performance. We present three protocols, named Multi-domain Secure Multiplication protocol (MSM), Secure Exponent Calculation protocol with private Base (SECB), and Secure Exponent …

Security Testing With Misuse Case Modeling, Samer Yousef Khamaiseh

Boise State University Theses and Dissertations

Having a comprehensive model of security requirements is a crucial step towards developing a reliable software system. An effective model of security requirements which describes the possible scenarios that may affect the security aspects of the system under development can be an effective approach for subsequent use in generating security test cases.

Misuse case was first proposed by Sinder and Opdahl as an approach to extract the security requirements of the system under development [1]. A misuse case is a use case representing scenarios that might be followed by a system adversary in order to compromise the system; that is …
