  1. Secure Group communication for First Responders [SGFR] By Ganesh Godavari

  2. Outline of Talk • About SGFR • Goals • Software Used • Work done till date • Conclusion

  3. SGFR • This project is sponsored by Network, Information and Space Security (NISSC) • Duration 3 months [June 03 – Aug 03 ] • Principal instructor • Dr Edward Chow, Computer Science, UCCS • Dr Chip Benight, Psychology Dept., UCCS

  4. Goal • The goal is to design a framework for enhancing groupware packages such as instant messenger and video conferencing tools with security through • scalable group key management (Keystone from UT Austin), and • secure model (Bell La Padula)

  5. Software Used • Jabberd • Jabber is an open XML protocol for the real-time exchange of messages and presence between any two points on the Internet. • JabberX • A console-mode client for Jabber • Keystone • A Group Key Management system that establishes and maintains group keys for a group of clients

  6. Work Done Till Date • Integrated JabberX with Keystone for secure group chatting. • Able to transfer files from one machine to all others in the group. • Need to add in the BLP model for file distribution.

  7. Conclusion • Need to modify keystone for error handling • Need to reduce keystone’s dependency on 2 encryption libraries i.e. Cryptolib-1.2, Openssl. Openssl’s crypto library must be sufficient enough. • Need to find another method for file transfer as the current way of file transfer i.e. broadcast is not good. • ( I know TCP broadcast is not used for file transfer ) • Have a partial access control provided by Keystone. Need to provide the access control for file transfer
