LAN Messenger
SVERIAN Scientific LAN Messenger Pooja Purohit, Sakhare Shital, Kothari Rasika and Jadhav Dipali Department of Computer Engineering, SVERI’s College of Engineering (Poly.), Pandharpur Student Article Abstract: This is LAN messenger application; it’s a social media project for Final year college students. It is a Client – server application program developed in Visual Studio 2005 (VB .NET). Here the individual can chat with other individual through LAN connection. Even they can exchange file through one computer to other. Administrator can view chat logs through server. Here no need of Internet access. This application can be used in all workplace which is helpful in submitting information and to connect with workplace staff. Introduction: A LAN messenger is an instant messaging program designed for use within a single local area network (LAN). Many LAN messengers offer basic functionality for sending private messages, file transfer , chat rooms and graphical smileys . The advantage of using a simple LAN messenger over a normal instant messenger is that no active Internet connection or central server is required - and only people inside the firewall will have access to the system. LAN messenger is an easy to use, server based LAN messaging application for effective communication. It is correctly identified and works under all operating systems with unlimited user accounts and is the only secure messenger. The simple interface makes special training needless . Literature Review: The LM uses two-tier client server architecture as shown in figure 1. The application handling is completed separately for database queries and updates and for business logic processing and user interface presentation. -

Instant Messaging
Instant Messaging what’s so gr8 about it? Cybertour | March 18 | Cindi Trainor 1 What is IM? Communicate real-time Users are notified when others come online Can share files, communicate via video with most programs IM vs “chat rooms”: When chat first came about, a user would log into a room full of people who were all interested in the same topic, and all those people saw everyone’s messages, but users could send “private” messages to an individual, if desired. IM is kind of the opposite: users primarily send messages to individuals but can set up multiple user chat rooms if desired (but users control who’s in a multi-user chat by invitation). 2 Why Use IM? Instant communication Send links, files, photos instantly Can multi-task Our users are familiar with it 3 Common Features Contacts list “Display picture” – an Customize your icon representing you messages’ Privacy features appearance Log conversations Games Set your status: Send and receive “away,” “offline,” files “busy,” etc. Multi-user chat Emoticons (“smilies”) Profiles With major IM programs, users add only the people that they want to chat with to a contacts list (buddy list, friends list). Messages’ appearance: font face, color, size Files: photos, dox, etc (can sometimes be slow vs using email with attachments) Multi-user chat: “chat rooms” Icons: some are static, some are animated or even customizable “avatars.” Privacy: can set it so that only your buddies can contact you; most have invisible mode 4 But… chat reference? IM is chat reference Hosted systems can be expensive, OR Use IM to supplement hosted system If you aren’t using chat reference in your library, IM is a cheap alternative to hosted systems to get your feet wet. -
Is Bob Sending Mixed Signals?
Is Bob Sending Mixed Signals? Michael Schliep Ian Kariniemi Nicholas Hopper University of Minnesota University of Minnesota University of Minnesota [email protected] [email protected] [email protected] ABSTRACT Demand for end-to-end secure messaging has been growing rapidly and companies have responded by releasing applications that imple- ment end-to-end secure messaging protocols. Signal and protocols based on Signal dominate the secure messaging applications. In this work we analyze conversational security properties provided by the Signal Android application against a variety of real world ad- versaries. We identify vulnerabilities that allow the Signal server to learn the contents of attachments, undetectably re-order and drop messages, and add and drop participants from group conversations. We then perform proof-of-concept attacks against the application to demonstrate the practicality of these vulnerabilities, and suggest mitigations that can detect our attacks. The main conclusion of our work is that we need to consider more than confidentiality and integrity of messages when designing future protocols. We also stress that protocols must protect against compromised servers and at a minimum implement a trust but verify model. 1 INTRODUCTION (a) Alice’s view of the conversa-(b) Bob’s view of the conversa- Recently many software developers and companies have been inte- tion. tion. grating end-to-end encrypted messaging protocols into their chat applications.

Skype Basics
Skype Basics: Instant Messaging can be used as a supplemental communication method to traditional emails and phone calls. Instant Messaging (or IM) is most useful for quick communications, either for a question that has a straightforward answer, or for a conversation that may not require a great deal of details. Winnefox receives Skype for Business as part of our Office365 subscription, and Winnefox staff have begun using it for IM messages; while Skype is more known for video calling, it can also send text-only messages, and has the benefit of being able to integrate with Outlook contacts, so that two separate user names do not need to be maintained. To set up Skype, log in to Office365 in a browser, using the URL https://portal.office.com; it will ask for the email address and password you use to log into Windows (if you do not use an email address to log into Windows, contact Pete Hodge). In the upper-left corner, click the “Office 365” link next to the grid, to bring you to the main landing page for Office365: On this page, go to the upper right side, to the “Install Office 365” link; beneath that, click on “Other Installs”. This brings up a page with all options for Office, including Skype for Business, on the left-hand side of the page. From the Skype for Business page, choose either “Skype for Business Basic (for Office 2016)” or “Skype for Business 2015”, depending on which is the same version as the other Office products installed on your computer. -
Sending Newsgroup and Instant Messages
7.1 LESSON 7 Sending Newsgroup and Instant Messages After completing this lesson, you will be able to: Send and receive newsgroup messages Create and send instant messages Microsoft Outlook offers some alternatives to communicating via e-mail. With instant messages, you can connect with a client who is also using instant messaging to ask a simple question and get the answer immediately. On the other hand, Newsgroups allow you to communicate with a larger audience. When considering the purchase of a new graphics program, for example, you can solicit advice and recommendations by posting a message to a newsgroup for people interested in graphics. You don’t need any practice files to work through the exercises in this lesson. Sending and Receiving Newsgroup Messages A newsgroup is a collection of messages related to a particular topic that are posted by individuals to a news server . Newsgroups are generally focused on discussion of a particular topic, like a sports team, a hobby, or a type of software. Anyone with access to the group can post to the group and read all posted messages. Some newsgroups have a moderator who monitors their use, but most newsgroups are not overseen in this way. A newsgroup can be private, such as an internal company newsgroup, but there are newsgroups open to the public for practically every topic. You gain access to newsgroups through a news server maintained either on your organization’s network or by your Internet service provider (ISP). You use a newsreader program to download, read, and reply to news messages. -
