Covert6: A Tool To Corroborate The Existence Of Ipv6 Covert Channels, Raymond A. Hansen, Lourdes Gino, Dominic Savio

Annual ADFSL Conference on Digital Forensics, Security and Law

Covert channels are any communication channel that can be exploited to transfer information in a manner that violates the system’s security policy. Research in the field has shown that, like many communication channels, IPv4 and the TCP/IP protocol suite have been susceptible to covert channels, which could be exploited to leak data or be used for anonymous communications. With the introduction of IPv6, researchers are acutely aware that many vulnerabilities of IPv4 have been remediated in IPv6. However, a proof of concept covert channel system was demonstrated in 2006. A decade later, IPv6 and its related protocols have undergone major …

Acceleration Of Statistical Detection Of Zero-Day Malware In The Memory Dump Using Cuda-Enabled Gpu Hardware, Igor Korkin, Iwan Nesterow

Annual ADFSL Conference on Digital Forensics, Security and Law

This paper focuses on the anticipatory enhancement of methods of detecting stealth software. Cyber security detection tools are insufficiently powerful to reveal the most recent cyber-attacks which use malware. In this paper, we will present first an idea of the highest stealth malware, as this is the most complicated scenario for detection because it combines both existing anti-forensic techniques together with their potential improvements. Second, we will present new detection methods which are resilient to this hidden prototype. To help solve this detection challenge, we have analyzed Windows’ memory content using a new method of Shannon Entropy calculation; methods of …

Using Computer Behavior Profiles To Differentiate Between Users In A Digital Investigation, Shruti Gupta, Marcus Rogers

Annual ADFSL Conference on Digital Forensics, Security and Law

Most digital crimes involve finding evidence on the computer and then linking it to a suspect using login information, such as a username and a password. However, login information is often shared or compromised. In such a situation, there needs to be a way to identify the user without relying exclusively on login credentials. This paper introduces the concept that users may show behavioral traits which might provide more information about the user on the computer. This hypothesis was tested by conducting an experiment in which subjects were required to perform common tasks on a computer, over multiple sessions. The …

Current Challenges And Future Research Areas For Digital Forensic Investigation, David Lillis, Brett A. Becker, Tadhg O’Sullivan, Mark Scanlon

Annual ADFSL Conference on Digital Forensics, Security and Law

Given the ever-increasing prevalence of technology in modern life, there is a corresponding increase in the likelihood of digital devices being pertinent to a criminal investigation or civil litigation. As a direct consequence, the number of investigations requiring digital forensic expertise is resulting in huge digital evidence backlogs being encountered by law enforcement agencies throughout the world. It can be anticipated that the number of cases requiring digital forensic analysis will greatly increase in the future. It is also likely that each case will require the analysis of an increasing number of devices including computers, smartphones, tablets, cloud-based services, Internet …

Forensic Analysis Of Ares Galaxy Peer-To-Peer Network, Frank Kolenbrander, Nhien-An Le-Khac, Tahar Kechadi

Annual ADFSL Conference on Digital Forensics, Security and Law

Child Abuse Material (CAM) is widely available on P2P networks. Over the last decade several tools were made for 24/7 monitoring of peer-to-peer (P2P) networks to discover suspects that use these networks for downloading and distribution of CAM. For some countries the amount of cases generated by these tools is so great that Law Enforcement (LE) just cannot handle them all. This is not only leading to backlogs and prioritizing of cases but also leading to discussions about the possibility of disrupting these networks and sending warning messages to potential CAM offenders. Recently, investigators are reporting that they are creating …

Counting Solutions To Discrete Non-Algebraic Equations Modulo Prime Powers, Abigail Mann

Mathematical Sciences Technical Reports (MSTR)

As society becomes more reliant on computers, cryptographic security becomes increasingly important. Current encryption schemes include the ElGamal signature scheme, which depends on the complexity of the discrete logarithm problem. It is thought that the functions that such schemes use have inverses that are computationally intractable. In relation to this, we are interested in counting the solutions to a generalization of the discrete logarithm problem modulo a prime power. This is achieved by interpolating to p-adic functions, and using Hensel's lemma, or other methods in the case of singular lifting, and the Chinese Remainder Theorem.

Secure Declassification In Faceted Javascript, Tam Wing

Master's Projects

Information leaks currently represent a major security vulnerability. Malicious code, when injected into a trusted environment and executed in the context of the victim’s privileges, often results in the loss of sensitive information. To address this security issue, this paper focuses on the idea of information flow control using faceted execution [3]. This mechanism allows the interpreter to efficiently keep track of variables across multiple security levels, achieving termination-insensitive non-interference (TINI). With TINI, a program can only leak one bit of data, caused by the termination of a program. One key benefit of having faceted execution is that flow policy …

Statistical Analysis Of Binary Functional Graphs Of The Discrete Logarithm, Mitchell Orzech

Mathematical Sciences Technical Reports (MSTR)

The increased use of cryptography to protect our personal information makes us want to understand the security of cryptosystems. The security of many cryptosystems relies on solving the discrete logarithm, which is thought to be relatively difficult. Therefore, we focus on the statistical analysis of certain properties of the graph of the discrete logarithm. We discovered the expected value and variance of a certain property of the graph and compare the expected value to experimental data. Our finding did not coincide with our intuition of the data following a Gaussian distribution given a large sample size. Thus, we found the …

Cyber Security Awareness In Higher Education, Toni Hunt

Symposium Of University Research and Creative Expression (SOURCE)

With technology advancing every day our society is becoming more connected than we have ever been before. While these advances are making our daily lives easier they are also adding extra risks to our personal information. Most people do not think about their identities getting stolen when they make an online purchase, check their email, or use social media. However, each time that you put your personal information on the Internet you are at risk of that information getting stolen. This is especially true for students, who spend so much time online doing school activities. Every time that they login …

The History Of Chinese Cybersecurity: Current Effects On Chinese Society Economy, And Foreign Relations, Vaughn C. Rogers

Seton Hall University Dissertations and Theses (ETDs)

Chinese cybersecurity has become an infamous topic in the field of cybersecurity today, causing a great deal of controversy. The controversy stems from whether or not censorship is hindering Chinese economy, society, and relationships with other countries. The White Papers (中国政府白皮书), the Constitution of the People’s Republic of China (中华人民共和国宪法), and The Internet in China (中国互联网状况) all suggest that there is a free flow of Internet both within and without China that promotes peaceful socioeconomic development which the Chinese government seeks to promote. But is China sacrificing lucrative business prospects to secure …

Taint And Information Flow Analysis Using Sweet.Js Macros, Prakasam Kannan

Master's Projects

JavaScript has been the primary language for application development in browsers and with the advent of JIT compilers, it is increasingly becoming popular on server side development as well. However, JavaScript suffers from vulnerabilities like cross site scripting and malicious advertisement code on the the client side and on the server side from SQL injection.

In this paper, we present a dynamic approach to efficiently track information flow and taint detection to aid in mitigation and prevention of such attacks using JavaScript based hygienic macros. We use Sweet.js and object proxies to override built-in JavaScript operators to track information flow …

Detecting Objective-C Malware Through Memory Forensics, Andrew Case

LSU New Orleans Theses and Dissertations

Memory forensics is increasingly used to detect and analyze sophisticated malware. In the last decade, major advances in memory forensics have made analysis of kernel-level malware straightforward. Kernel-level malware has been favored by attackers because it essentially provides complete control over a machine. This has changed recently as operating systems vendors now routinely enforce driving signing and strategies for protecting kernel data, such as Patch Guard, have made userland attacks much more attractive to malware authors.

In this thesis, new techniques for detecting userland malware written in Objective-C on Mac OS X are presented. As the thesis illustrates, Objective-C provides …

Information Technology Proposal For The Town Of Spencer, Vijay Basava, Corey Kenyon, Mahdi Soltani

School of Professional Studies

The Town of Spencer came to us looking for a plan to build and maintain their own personal fiber network for connection between departments and to improve data security for important information. After assessing the existing landscape and determining the various paths forward, we created network diagrams and plans for the movement forward of this project.

After assessing a variety of plans, we found that a full single-mode fiber network would be the best system for the implementation in Spencer. While it was the highest cost, it also scored the highest in our assessment.

Anonymous Identity-Based Broadcast Encryption With Chosen-Ciphertext Security, Kai He, Jian Weng, Jia-Nan Liu, Joseph K. Liu, Wei Liu, Deng, Robert H.

Research Collection School Of Computing and Information Systems

In this paper, we propose the first identity-based broadcast encryption scheme, which can simultaneously achieves confidentiality and full anonymity against adaptive chosen-ciphertext attacks under a standard assumption. In addition, two further desirable features are also provided: one is fully-collusion resistant which means that even if all users outside of receivers S collude they cannot obtain any information about the plaintext. The other one is stateless which means that the users in the system do not need to update their private keys when the other users join or leave our system. In particular, our scheme is highly efficient, where the public …

Efficient Verifiable Computation Of Linear And Quadratic Functions Over Encrypted Data, Ngoc Hieu Tran, Hwee Hwa Pang, Robert H. Deng

Research Collection School Of Computing and Information Systems

In data outsourcing, a client stores a large amount of data on an untrusted server; subsequently, the client can request the server to compute a function on any subset of the data. This setting naturally leads to two security requirements: confidentiality of input data, and authenticity of computations. Existing approaches that satisfy both requirements simultaneously are built on fully homomorphic encryption, which involves expensive computation on the server and client and hence is impractical. In this paper, we propose two verifiable homomorphic encryption schemes that do not rely on fully homomorphic encryption. The first is a simple and efficient scheme …
