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

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

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

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)

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

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.

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
