Secure Portable Execution Environments: A Review Of Available Technologies, Peter James Jan 2008

Secure Portable Execution Environments: A Review Of Available Technologies, Peter James

Australian Information Security Management Conference

Live operating systems and virtualisation allow a known, defined, safe and secure execution environment to be loaded in to a PC’s memory and executed with either minimal or possibly no reliance on the PC’s internal hard disk drive. The ability to boot a live operating system or load a virtual environment (containing an operating system) from a USB storage device allows a secure portable execution environment to be created. Portable execution environments have typically been used by technologists, for example to recover data from a failing PC internal hard disk drive or to perform forensic analysis. However, with the commercial …

Security Issues Of Ieee 802.16 (Wimax), Jamshed Hasan Dec 2006

Security Issues Of Ieee 802.16 (Wimax), Jamshed Hasan

Australian Information Security Management Conference

Worldwide Interoperability for Microwave Access (WiMAX) is going to be an emerging wireless technology for the future. With the increasing popularity of Broadband internet, wireless networking market is thriving. Wireless network is not fully secure due to rapid release of new technologies, market competition and lack of physical infrastructure. In the IEEE 802.11 technology, security was added later. Iin IEEE 802.16, security has been considered as the main issue during the design of the protocol. However, security mechanism of the IEEE 802.16 (WiMAX) still remains a question. WiMAX is relatively a new technology; not deployed widely to justify the evidence …

Security Analysis Of Two Signcryption Schemes, Guilin Wang, Robert H. Deng, Dongjin Kwak, Sangjae Moon Sep 2004

Security Analysis Of Two Signcryption Schemes, Guilin Wang, Robert H. Deng, Dongjin Kwak, Sangjae Moon

Research Collection School Of Computing and Information Systems

Signcryption is a new cryptographic primitive that performs signing and encryption simultaneously, at a cost significantly lower than that required by the traditional signature-then-encryption approach. In this paper, we present a security analysis of two such schemes: the Huang-Chang convertible signcryption scheme, and the Kwak-Moon group signcryption scheme. Our results show that both schemes are insecure. Specifically, the Huang-Chang scheme fails to provide confidentiality, while the Kwak-Moon scheme does not satisfy the properties of unforgeability, coalition-resistance, and traceability.

Making The Key Agreement Protocol In Mobile Ad Hoc Network More Efficient, Gang Yao, Kui Ren, Feng Bao, Robert H. Deng, Dengguo Feng Oct 2003

Making The Key Agreement Protocol In Mobile Ad Hoc Network More Efficient, Gang Yao, Kui Ren, Feng Bao, Robert H. Deng, Dengguo Feng

Research Collection School Of Computing and Information Systems

Mobile ad hoc networks offer convenient infrastructureless communications over the shared wireless channel. However, the nature of mobile ad hoc networks makes them vulnerable to security attacks, such as passive eavesdropping over the wireless channel and denial of service attacks by malicious nodes. To ensure the security, several cryptography protocols are implemented. Due to the resource scarcity in mobile ad hoc networks, the protocols must be communication efficient and need as less computational power as possible. Broadcast communication is an important operation for many application in mobile ad hoc networks. To securely broadcast a message, all the members in the …
