The Extensible Messaging and Presence Protocol (XMPP) is one of the most popular Instant Messaging (IM) protocols which uses a client-server working mode. This protocol uses different connection primitives for both client-to-server (c2s) and server-to-server (s2s) connections. It is actively used in mission-critical operations where the reliability and security of communication systems is always imperative...
Pidgin communicator is a multiprotocol instant messenger client, developed by open source community. It was originally a third party client of AIM (AOL Instant Messenger) protocol for Linux operating system founded in 1998. At present, its main goal is to provide common interface for every protocol it supports, so the user does not need care about protocol to use or peer's IM identifier, while he...
The rapid development of instant messaging changes the people's communication, collaboration and entertainment manner radically. Unfortunately, the existing instant messaging technology does not provide built-in support for security features. The security problem of instant messaging system has aroused widespread concern in both academia and industry. In this paper, we proposed a new and secure instant...
In Recent years, the development of smart home applications based on OSGi framework has attracted increasing attention on the delivery of services on heterogeneous devices or platforms. In OSGi framework, bundles communicate with each other through service layer. However, the communication across OSGi frameworks for sharing services or exchanging information is rather limited and has no standard definition...
A common assumption for the state-of-the-art methods of protocol testing is that the protocol description is precise, unambiguous and fully determined. Unfortunately, in many practical situations this assumption turns out to be unrealistic. We propose an architecture of a testing framework where different aspects and facets of protocols are separated in a clear manner so that the adaptation of the...
Based on the deep analysis of IM texts, files and audio protocol characteristics, an instant messenger monitoring system is designed and implemented. By means of capture techniques of network data packets, protocol characteristic identification techniques based on regular expression, and storage strategy for transfer files, the presented monitoring system can monitor texts, transfer files and audio...
The most common method of system administration is accessing the remote system through the network by means of some client-server protocol, giving access to a privileged service always listening on the target system. There are important security and flexibility limitations deriving from the usage of a predictable access port for such a critical application, which can be summarized as the impossibility...
The theory of open complex giant system (OCGS) and its corresponding methodology named Hall for Workshop of Metasynthesis Engineering (HWME) were proposed in 1990s. Many implementations of HWME system have emerged in recent years. As the basis of the HWME system, communication platform became the key factor gradually. At the same time, instant messaging (IM) is more and more popular as the internet...
