	[STW96] *M. Steiner, G. Tsudik and M. Waidner,* *Diffie-Hellman Key Distribution Extended to Groups* *ACM CCS'96, March 1996*
		This paper introduces the group Diffie-Hellman key agreement protocols GDH.1-3 and proves their security.
	[STW97] *M. Steiner, G. Tsudik and M. Waidner* *CLIQUES: A New Approach to Group Key Agreement* *IEEE ICDCS'97, May 1997*
		This paper extendes STW96 to support dynamic membership (auxhiliary key agreement) operations. Protocols for join, leave, partition, and merge are defined and proven secure.
	[AST98] *G. Ateniese, M. Steiner and G. Tsudik* *Authenticated Group Key Agreement and Friends* *ACM CCS'98, November 1998*
		A notion of group key authenitication is considered and a concrete (provably-secure) authenticated group key agreement protocol is proposed.
	[ACHKT00] *G. Ateniese, O. Chevassut, D. Hasse, Y. Kim and G. Tsudik* *The Design of a Group Key Agreement API* *DARPA DISCEX 2000, Jan. 2000*
		This paper describes the Cliques GDH application protocol interface (CLQ_API) which implements GDH.2 and GDH.3 using OpenSSL. CLQ_API is independent of the underlying communication system.
	[AAHKNSSST00] *Y. Amir, G. Ateniese, D. Hasse, Y. Kim, C. Nita-Rotaru, T. Schlossnagle, J. Schultz, J. Stanton and G. Tsudik* *Secure Group Communication in Asynchronous Networks with Failures: Integration and Experiments, IEEE ICDCS 2000, April 2000.*
		This paper reports on the integration of Cliques with Spread group communication system developed at Johns Hopkins University.
	[AST00] *G. Ateniese, M. Steiner and G. Tsudik* *New Multi-party Authentication Services and Key Agreement Protocols* *IEEE Journal on Selected Areas in Communication, May 2000.*
		Journal version of ATW98; also defines a complete authentication protocol (strong authentication among all members).
	[STW00] *M. Steiner, G. Tsudik and M. Waidner* *Key Agreement in Dynamic Peer Groups* *IEEE Transactions on Parallel and Distributed Systems, August 2000.*
		Journal version of STW96 and STW97; enhances and refines prior results.
	[KPT00] *Y. Kim. A. Perrig and G. Tsudik* *Simple and Fault-Tolerant Key Agreement for Dynamic Collaborative Groups, ACM CCS 2000, November 2000.*
		New group key agreement protocol based on Diffie-Hellman key trees. Computation complexity is reduced from O(n) to O(log n).
	[ACTT01] *D. Agarwal, O. Chevassut, M. R. Thompson, and G. Tsudik* *An Integrated Solution for Secure Group Communication in Wide-Area Networks, ISCC 2001, Jul. 2001.*
		Integration of Cliques with Totem group communication system. Authorization issues are also considered.
	[KPT01] *Y. Kim. A. Perrig and G. Tsudik* *Communication-Efficient Group Key Agreement, IFIP SEC 2001, Jun. 2001.*
		New group key agreement protocol based on Diffie-Hellman key tree. Communication cost is optimized.
	[AKNT01] *Y. Amir, Y. Kim, C. Nita-Rotaru and G. Tsudik* *On the Performance of Group Key Agreement Protocols, ICDCS 2002, July 2002.*
		Theoretical comparison and actual measurement over LAN/WAN of five group key management protocols integrated with Spread group communication system
