An active attack on a multiparty key exchange protocol

Abstract

The multiparty key exchange introduced in Steiner et al. and presented in more general form by the authors is known to be secure against passive attacks. In this paper, an active attack is presented assuming malicious control of the ommunications of the last two users for the duration of only the
key exchange.

Keywords

• Multiparty key exchange
• Active attacks
• Group actions
