ABSTRACT	We examine multi-party key agreement protocols that provide (i) key authentication, (ii) key confirmation and (iii) forward secrecy. Several minor (repairable) attacks are presented against previous two-party key agreement schemes and a model for key agreement is presented that provably provides the properties listed above. A generalization of the Burmester-Desmedt model (Eurocrypt '94) for multi-party key agreement is given, allowing a transformation of any two-party key agreement scheme into a multi-party scheme. Multi-party schemes (based on the general model and two specific 2-party schemes) are presented that reduce the number of rounds required for key computation compared to the specific Burmester-Desmedt scheme. It is also shown how the specific Burmester-Desmedt scheme fails to provide key authentication. 1991 AMS Classification: 94A60 CR Categories: D.4.6 Key Words: multi-party, key agreement, key authentication, key confirmation, forward secrecy.
