Whitepaper: Secure and Reliable Java-Based Middleware - Challenges and Solutions

by Ecole Polytechnique Federale de LausanneJan 13, 2012

Java and the Java Virtual Machine (JVM) are a predominant programming language and deployment platform for complex, component-oriented systems. This white paper is an overview of shortcomings in the JVM that hinder the development of secure and reliable component execution platforms. Java-based middleware is designed for component-oriented application development the underlying Java runtime system does not provide the necessary means to guarantee security and reliability with presence of


Whitepaper: Entrepreneurship, Technological Change And Endogenous Returns To Ability

by Ecole Polytechnique Federale de LausanneJan 13, 2012

This paper published by Ecole Polytechnique proposes a model of entrepreneurial activity highlighting a non-monotone relationship between technological change and ability-based sorting into entrepreneurial types. Entrepreneurial decisions are examined in a two-stage model under uncertainty in which entrepreneurs decide to abandon a project and start a new venture depending on technological change and on ability. The paper investigates how technological change affects the comparative advantage of


Whitepaper: An FPGA Dynamically Reconfigurable Framework for Modular Robotics

by Ecole Polytechnique Federale de LausanneJan 12, 2012

This paper published by FPGA proposes a framework for performing it in an easy way, for a specific application: Modular Robotics. An architecture containing a Microblaze processor and a reconfigurable module is proposed. The presented approach may increase system flexibility thanks to DPR, while keeping low memory requirements given the Bluetooth access to a bitstream repository.


Whitepaper: Fuelling WiFi Deployment: A Reputation-Based Solution

by Ecole Polytechnique Federale de LausanneJan 12, 2012

Wi-Fi networks have a very strong potential: They are easy to deploy, they use free spectrum frequencies and they allow the users to have an Internet connection that is several times faster that any cable modem connection. Furthermore, the equipment is inexpensive. The rapid growth of WiFi over the past two years reveals the willingness of the Wireless Internet Service Providers (WISPs) to develop this technology and the interest of the users in this new service. This research paper presents a


Whitepaper: Reducing Time Complexity in RFID Systems

by Ecole Polytechnique Federale de LausanneJan 12, 2012

Radio frequency identification systems based on low-cost computing devices is the new plaything that every company would like to adopt. Its goal can be either to improve the productivity or to strengthen the security. Specific identification protocols based on symmetric challenge response have been developed to assure the privacy of the device bearers. Although these protocols fit the devices’ constraints, they always suffer from a large time complexity. This white paper shows that their
