Optimal Energy-Delay Routing Protocol With Trust Levels For Wireless Ad Hoc Networks, Eyad Taqieddin, Ann K. Miller, Jagannathan Sarangapani
Optimal Energy-Delay Routing Protocol With Trust Levels For Wireless Ad Hoc Networks, Eyad Taqieddin, Ann K. Miller, Jagannathan Sarangapani

This paper presents the Trust Level Routing (TLR) pro- tocol, an extension of the optimized energy-delay rout- ing (OEDR) protocol, focusing on the integrity, reliability and survivability of the wireless network. TLR is similar to OEDR in that they both are link state routing proto- cols that run in a proactive mode and adopt the concept of multi-point relay (MPR) nodes. However, TLR aims at incorporating trust levels into routing by frequently changing the MPR nodes as well as authenticating the source node and contents of control packets. TLR calcu- lates the link costs based on a composite metric (delay …
Simple, Secure, Selective Delegation In Online Identify Systems, Bryant Gordon Cutler
Simple, Secure, Selective Delegation In Online Identify Systems, Bryant Gordon Cutler
Theses and Dissertations
The ability to delegate privileges to others is so important to users of online identity systems that users create ad hoc delegation systems by sharing authentication credentials if no other easy delegation mechanism is available. With the rise of internet-scale relationship-based single sign-on protocols like OpenID, the security risks of password sharing are unacceptable. We therefore propose SimpleAuth, a simple modification to relationship-based authentication protocols that gives users a secure way to selectively delegate subsets of their privileges, making identity systems more flexible and increasing user security. We also present a proof-of-concept implementation of the SimpleAuth pattern using the sSRP …

Enhanced Security For Preventing Man-In-The-Middle Attacks In Authentication, Dataentry And Transaction Verification, Jason Wells, Damien Hutchinson, Justin Pierce
Australian Information Security Management Conference
There is increasing coverage in the literature highlighting threats to online financial systems. Attacks range from the prevalent reverse social engineering technique known as phishing; where spam emails are sent to customers with links to fake websites, to Trojans that monitor a customer’s account log on process that captures authentication details that are later replayed for financial gain. This ultimately results in loss of monetary funds for affected victims. As technological advances continue to influence the way society makes payment for goods and services, the requirement for more advanced security approaches for transaction verification in the online environment increases. This …
Wireless Authentication Using Remote Passwords, Andrew S. Harding
Wireless Authentication Using Remote Passwords, Andrew S. Harding
Theses and Dissertations
Current authentication methods for wireless networks are difficult to maintain. They often rely on globally shared secrets or heavyweight public-key infrastructure. Wireless Authentication using Remote Passwords (WARP) mitigates authentication woes by providing usable mechanisms for both administrators and end-users. Administrators grant access by simply adding users' personal messaging identifiers (e.g., email addresses, IM handles, cell phone numbers) to an access control list. There is no need to store passwords or other account information. Users simply prove ownership of their authorized identifier to obtain wireless access.
