The Research and Implementation of EAP - FAST Protocol in Public Wireless Local Area Network

Cao Ping,Pei Wenjiang

Strategic Study of CAE 2005, Volume 7, Issue 12,   Pages 78-82

Abstract:

Since the LEAP wireless authentication protocol is vulnerable to dictionary attacks, the flexibleauthentication via secure tunneling (EAP - FAST) was introduced by Cisco Corporation in 2004, which establishesa mutually authenticated protected tunnel to protect the authentication data.research and design this protocol in public wireless local area network, and implement the function of EAP- FAST peer, authenticator and FAST server in PWLAN integrate experimentation flat.

Managing obsolescence of embedded hardware and software in secure and trusted systems

Zachary A. COLLIER, James H. LAMBERT

Frontiers of Engineering Management 2020, Volume 7, Issue 2,   Pages 172-181 doi: 10.1007/s42524-019-0032-5

Abstract: Obsolescence of integrated systems which contain hardware and software is a problem that affects multiple industries and can occur for many reasons, including technological, economic, organizational, and social factors. It is especially acute in products and systems that have long life cycles, where a high rate of technological innovation of the subcomponents result in a mismatch in life cycles between the components and the systems. While several approaches for obsolescence forecasting exist, they often require data that may not be available. This paper describes an approach using non-probabilistic scenarios coupled with decision analysis to investigate how particular scenarios influence priority setting for products and systems. Scenarios are generated from a list of emergent and future conditions related to obsolescence. The key result is an identification of the most and least disruptive scenarios to the decision maker’s priorities. An example is presented related to the selection of technologies for energy islanding, which demonstrates the methodology using six obsolescence scenarios. The paper should be of broad interest to scholars and practitioners engaged with enterprise risk management and similar challenges of large-scale systems.
