A Conceptual Model For Federated Authentication In The Cloud, Abdulwahid Al Abdulwahid, Nathan Clarke, Steven Furnell, Ingo Stengel
A Conceptual Model For Federated Authentication In The Cloud, Abdulwahid Al Abdulwahid, Nathan Clarke, Steven Furnell, Ingo Stengel
Australian Information Security Management Conference
Authentication is a key security control for any computing system, whether that is a PC, server, laptop, tablet or mobile phone. However, authentication is traditionally poorly served, with existing implementations falling foul of a variety of weaknesses. Passwords are poorly selected, reused and shared (to name but a few). Research has suggested novel approaches to authentication such as transparent authentication and cooperative and distributed authentication. However, these technologies merely focus upon individual platforms rather than providing a universal and federated authentication approach that can be used across technologies and services. The advent of cloud computing, its universal connectivity, scalability and …
Security Of Internet Protocol Cameras – A Case Example, William Campbell
Security Of Internet Protocol Cameras – A Case Example, William Campbell
Australian Digital Forensics Conference
The interaction of consumer devices and the internet, especially in relation to security, has always been tenuous. Where it is in the best interests of companies to produce products that are cheap and accessible, these traits often go against that of security. This investigation undertakes an analysis of one such device – the DCS 930L internet protocol camera from D Link. This camera is analysed for vulnerabilities, with an emphasis on those relating to authentication mechanisms. Several vulnerabilities are identified, and potential attacks based on these are discussed. Solutions or mitigations to these vulnerabilities are presented.
A Secure And Effective Anonymous User Authentication Scheme For Roaming Service In Global Mobility Networks, Fengtong Wen, Willy Susilo, Guomin Yang
A Secure And Effective Anonymous User Authentication Scheme For Roaming Service In Global Mobility Networks, Fengtong Wen, Willy Susilo, Guomin Yang
Research Collection School Of Computing and Information Systems
In global mobility networks, anonymous user authentication is an essential task for enabling roaming service. In a recent paper, Jiang et al. proposed a smart card based anonymous user authentication scheme for roaming service in global mobility networks. This scheme can protect user privacy and is believed to have many abilities to resist a range of network attacks, even if the secret information stored in the smart card is compromised. In this paper, we analyze the security of Jiang et al.’s scheme, and show that the scheme is in fact insecure against the stolen-verifier attack and replay attack. Then, we …
Technique For Authenticating H.264/Svc Streams In Surveillance Applications, Wei Zhuo, Robert H. Deng, Jialie Shen, Yongdong Wu, Xuhua Ding, Swee Won Lo
Technique For Authenticating H.264/Svc Streams In Surveillance Applications, Wei Zhuo, Robert H. Deng, Jialie Shen, Yongdong Wu, Xuhua Ding, Swee Won Lo
Research Collection School Of Computing and Information Systems
Surveillance codestreams coded by H.264/SVC (scalable video coding), which consists of one base layer and one or more enhancement layers, supply flexible and various quality, resolution, and temporal (sub)codestreams such that clients with different network bandwidth and terminal devices can seamlessly access them. In this paper, we present a robust authentication scheme for them in order to insure the integrity of SVC surveillance codestreams, named AUSSC (Authenticating SVC Surveillance Codestreams). AUSSC exploits cryptographic-based authentication for base layer and content-based authentication for enhancement layers. For content-based authentication, AUSSC extracts full features from the first frame of each GOP (group of picture) …
Hybrid Spread-Spectrum Tcp For Combating Fraudulent Cyber Activities Against Reconnaissance Attacks, Simon Enoch Yusuf, Olumide Longe
Hybrid Spread-Spectrum Tcp For Combating Fraudulent Cyber Activities Against Reconnaissance Attacks, Simon Enoch Yusuf, Olumide Longe
The African Journal of Information Systems
The inefficiencies of current intrusion detection system against fraudulent cyber activities attracts the attention of computer gurus, also known as “hackers” to exploit known weakness on a particular host or network. These hackers are expert programmers who mainly focus on how the Internet works, and they interact with each other to know its strengths and weaknesses. Then they develop advanced tools which an average attacker with little background can use to know the liveness, reachability and running service on the network. Once an attacker identifies these details, he can accurately launch an effective attack and get maximum benefit out of …
Exploiting Human Factors In User Authentication, Payas Gupta
Exploiting Human Factors In User Authentication, Payas Gupta
Dissertations and Theses Collection (Open Access)
Our overarching issue in security is the human factor – and dealing with it is perhaps one of the biggest challenges we face today. Human factor is often described as the weakest part of a security system and users are often described as the weakest link in the security chain. In this thesis, we focus on two problems which are caused by human factors in user authentication and propose respective solutions. a) Secrecy information inference attack – publicly available information can be used to infer some secrecy information about the user. b) Coercion attack – where an attacker forces a …
