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...
The rapid growth in market demands for high-quality, state-of-the-art, and reliable communication services increases the amount of session-control signaling, which is mainly based on the Session Initiation Protocol (SIP). Many research activities dealing with the Quality of Service (QoS) have been focused on media-related service components, whereas signaling-related service components have received...
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...
Signal is a new security protocol and accompanying app that provides end-to-end encryption for instant messaging. The core protocol has recently been adopted by WhatsApp, Facebook Messenger, and Google Allo among many others, the first two of these have at least 1 billion active users. Signal includes several uncommon security properties (such as "future secrecy" or "post-compromise...
The development of wireless technology like Internet Protocol version 6 over Low power Wireless Personal Area Networks, which defines IP communication for resource-constrained networks enables communication on the lower layers, while the diverging and incompatible application layer protocols lead to barriers in the way of information transferring between heterogeneous networks. Fortunately, extensible...
Currently, web and mobile-based systems exchange information with other services, mostly through APIs that extend the functionality and enable multipart interoperable information exchange. Most of this is accomplished through the usage of RESTful APIs and data exchange that is conducted using JSON over the HTTP or HTTPS protocol. In the case of the exchange requires some specific security requirements,...
Secure end-to-end communication has become a necessity for many people. In this research paper we survey the most popular and widely used secure anonymous Instant Messaging (IM) services and protocols, study them from a security and anonymity point of view, and investigate how these services or protocols could be compromised.
The Mobile Instant Messaging Service (MIMS) is a popular feature on mobile communication devices today. It is a powerful and cheap facility to send and to receive messages through a handheld portable tool. Currently, many MIMS applications are available to support humans' activities in their everyday life. However, the security of this service needs to be increased for further applications such as...
Nowadays instant messaging (IM), as a viable communication tool, has been widely adopted in the business field. Instant messaging delivers lots of benefits for business, but most people are unaware of its security problems and other potential implications. This paper focuses on investigating the problems and issues associated with the instant messaging in business. The existing literature is critically...
Number of instant messaging (chat) applications grows rapidly, not only in everyday communication of ordinary people, but in business correspondence. Consequently, security and privacy of these kinds of applications are very important. In this paper, CryptoCloak protocol for secure and private chat communication is introduced, together with the prototype IM application implemented in Java programming...
Quantum communication is a new interdisciplinary branch of science which has been developing during the past two decades, which is a new research field combining quantum theory and information theory. Quantum communication is characterized by some features such as being highly efficient and absolutely safe, which is now a hot research area in quantum physics and information science around the world...
Instant Messaging systems are widely used in social software, especially in the mobile Internet era. With the diversified and rapid development of mobile terminal, the systems play an important role in the mobile platform. In this paper, we introduce a kind of technology to implement the cross-platform instant messaging system, which through the HTTP protocol, XMPP protocol, TCP protocol and SSH,...
Mobile Instant Messenger is one of the most application which use to exchange a message between Sender and Receiver over public network, so that it is very important building an application with good level of security aspect and fast communication. This paper propose a secure Mobile IM in excanging data over internet with an virtual network method. In this model, we propose a Mobile Instant Messenger...
In today's world, businesses are under enormous pressure to reduce operational and capital expenditures related to their use of communications technologies. Businesses are also looking into re-organizing to work more collaboratively and efficiently. Unified Communication (UC), the integration of two or more real time communication systems into one platform, is a viable solution in tackling this pressure...
This paper compares two telecommunication standards for plaintext transmission over Session Initiation Protocol (SIP): SIP extension for Text over Internet Protocol (ToIP) and SIP extension for Instant Messaging (IM). ToIP provides a real-time text service, while IM provides a near realtime text service. Originally, SIP is a Voice over Internet Protocol (VoIP) call signaling protocol that uses Real-time...
Instant messaging (IM) stands for a visual mode of communication with the chance of real time responses but without (needed or wished) face-to-face contacts. In particular, youngsters prefer instant messengers to kill time if they are bored and nothing else within range interests them. Harmfully, they may get in touch with inappropriate language there. Much worse, their habitation in such virtual...
After analyzing SRTP (Secure Real-time Transport Protocol) and SIP(session initiation protocole), we identified the need to secure VoIP(Voice over IP) network. Ourstudy assesses the risk of attacks on the VoIP network. Additionally, it offers solutions to the existing VoIP network vulnerabilities while issuing Instant Messages. Using cryptography, we present a general proposal for secure VoIP instant...
Messaging of course has always been a core feature of the Internet. Jabber is a compelling IM solution that is well-suited to meet today's and tomorrow's IM needs. The Jabber system is technically simple, flexible, and surprisingly intuitive. Jabber's open standards are its primary political and business advantage, its use of XML as its standard data format is its crucial technical advantage. A Jabber...
WebRTC, browser-to-browser communication technology, has on short term a desktop strategy, which will unleash its potential in 2013/2014. It is a great opportunity for Telco's to achieve a promise of service continuity for the RCS standard. But general disintermediation patterns and WebRTC going mobile and being an API of its own, are a serious mid-term challenge for operators.
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...
