Fast Authentication in Heterogeneous Wireless Networks
The growing diffusion of wireless devices is leading to an increasing demand for mobility and security. At the same time, most applications can only tolerate short breaks in the data flow, so that it is a challenge to find out mobility and authentication methods able to cope with these constraints. This paper aims to propose an authentication scheme which significantly shortens the authentication latency and that can be deployed in a variety of wireless environments ranging from common Wireless LANs (WLANs) to satellite-based access networks

A modularized electronic payment system for agent-based e-commerce
With the explosive growth of the Internet, electronic-commerce (e-commerce) is an increasingly important segment of commercial activities on the web. The Secure Agent Fabrication, Evolution & Roaming (SAFER) architecture was proposed to further facilitate e-commerce using agent technology. In this paper, the electronic payment aspect of SAFER will be explored. The Secure Electronic Transaction (SET) protocol and E-Cash were selected as the bases for the electronic payment system implementation. The various modules of the payment system and how they interface with each other are shown. An extensible implementation done using JavaTM will also be elaborated. This application incorporates agent roaming functionality and the ability to conduct e-commerce transactions and carry out intelligent e-payment procedures
The Horcrux Protocol: A Method for Decentralized Biometric-based Self-sovereign Identity
Most user authentication methods and identity proving systems rely on a
centralized database. Such information storage presents a single point of
compromise from a security perspective. If this system is compromised it poses
a direct threat to users' digital identities. This paper proposes a
decentralized authentication method, called the Horcrux protocol, in which
there is no such single point of compromise. The protocol relies on
decentralized identifiers (DIDs) under development by the W3C Verifiable Claims
Community Group and the concept of self-sovereign identity. To accomplish this,
we propose specification and implementation of a decentralized biometric
credential storage option via blockchains using DIDs and DID documents within
the IEEE 2410-2017 Biometric Open Protocol Standard (BOPS)
AliEnFS - a Linux File System for the AliEn Grid Services
Among the services offered by the AliEn (ALICE Environment
http://alien.cern.ch) Grid framework there is a virtual file catalogue to allow
transparent access to distributed data-sets using various file transfer
protocols. (AliEn File System) integrates the AliEn file catalogue as
a new file system type into the Linux kernel using LUFS, a hybrid user space
file system framework (Open Source http://lufs.sourceforge.net). LUFS uses a
special kernel interface level called VFS (Virtual File System Switch) to
communicate via a generalised file system interface to the AliEn file system
daemon. The AliEn framework is used for authentication, catalogue browsing,
file registration and read/write transfer operations. A C++ API implements the
generic file system operations. The goal of AliEnFS is to allow users easy
interactive access to a worldwide distributed virtual file system using
familiar shell commands (f.e. cp,ls,rm ...) The paper discusses general aspects
of Grid File Systems, the AliEn implementation and present and future
developments for the AliEn Grid File System.Comment: 9 pages, 12 figure
