| Popis: | 97 Design and Implement of a Secure Instant Messaging System with Smart Card Abstract Instant Messaging (IM) is one of the most important Internet applications that enable real-time exchange messages through personal computers. IM allows users to send texts, audio and video files, and other types file. People are using IM both for personal and business reasons. However, most IM systems are not secure. In order to find a solution to secure IM communications, we designed and implemented a Secure Instant Messaging and Presence Protocol (SIMPP) for the Third-Party (two users and one server) IM communication models. The SIMPP is base on elliptic-curve cryptography. At the same time to enhance the security and convenience. We simplify some process to enter SIMPP with contact and contactless smart card. The proposed IM service is compatible with IETF XMPP (eXtensible Messaging and Presence Protocol) Standard. We choose jabberd2 software to create a SIMPP server on the Linux Platform, wherein we used Borland C++ Builder 6 to create a SIMPP client on the Windows platform.
