This poster presents new perspectives for open and trusted mobile applications. The Near Field Communication (NFC) radio interface is widely available for smartphones. It is usually involved in payments, access control, and transport services. We describe an open experimental platform, developed by the MOBISIM project. The prototype provides contactless payments in legacy frameworks. It comprises...
While originating as an instant messaging infrastructure, the eXtensible Messaging and Presence Protocol (XMPP) has its applications as a lightweight middleware for real-time event distribution, e.g. for mobile computing or the Internet of Things. Services based on XMPP are traditionally realized as server components with simple local registration for discovery, which is not appropriate for distributed...
Wireless Local Area Networks (WLANs) based on the IEEE 802.11 standards are becoming increasingly popular in businesses, governments, educations, public and individual. However, when transmissions are broadcast over radio waves, interception and masquerading becomes trivial to anyone with a radio, and so there is a need to employ additional mechanisms to protect the communication. In this paper, we...
In these days, there are many attempts for convergence with several types of networks. Jang proposed a new initial setup in SNMPv3 to enhance the secure network operation suitable for sensor networks. This model requires more time at initial step than previous models. For mobile ad-hoc networks where connections are established dynamically, simplification of initial step is needed. Therefore, we propose...
The seamless combining with context-aware sensors and numerous devices and e-home server will soon become a part of our home environment in the near future. We name it as a context-aware home based on ubiquitous computing concept. This context-aware home reduces participations of users in order to realize a ubiquitous computing and automates various services. Therefore, the risk of privacy violation...
In order to encapsulate data and to convey information more efficiently and more security, a draft frame based on active block ciphers for application layer of Internet which could transmit orange data into semantic security and semantic integrity was designed according to scalable purpose. To different network environment, there were different intelligent choices about block cipher algorithms to...
The increased availability of mobile broadband connec- tions enables the expansion of software downloads to mobile devices. This leads to greater number of available services and a better utilisation of the computational power of mobile devices. The downside of this increased software availability is an increase in the possible attack vectors. One scenario is the misuse of resources, for example,...
The paper describes a revised version of Crypto-fraglets, and an enhancement of the framework with access control mechanisms. Fraglets is an interesting computing model that has connections with communication protocols, formal rewriting systems and biological systems. Indeed, fraglets basic mechanisms resemble bio-chemical reactions.
This is an introduction to the proceedings of the MWS 2007 workshop held at EDOC 2007. It first explains the motivation for and background of the workshop. Then, it contains a short description of the keynote, each long and short peer-reviewed paper, and the discussion session "impact of various execution environments on middleware for web services". After the closing statements, MWS 2007...
Expected growth in use and implementation of wireless sensor networks (WSNs) in different environments and for different applications creates new security challenges. In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence...
This paper proposes a fast forward medium access control protocol (FFMAC) for quality-of-service (QoS) guarantee in multihop IEEE 802.11s wireless mesh networks with multiple channels. To the best of our knowledge, the proposed protocol is the first one which considers the multihop and multichannel issues simultaneously. It provides higher priority for real-time applications, while remaining the distributed...
