Source authentication of messages is a valuable tool incommunication networks where the source of a message caneasily be spoofed. Often, when two parties are communicating,a shared-key message authentication code is sufficientfor providing source authentication to both parties. Unfortunately,the utility of a MAC does not extend to a broadcastsituation involving three or more parties, so public-key digitalsignatures have traditionally been used to attain sourceauthentication in group broadcast communications. In thispaper we introduce HORSE, an r-time signature schemethat yields source authentication in the group setting likea public-key signature scheme, only with signature and verificationtimes much closer to those of a MAC. Additionally,HORSE makes much more efficient use of its keys than previousr-time signature schemes.
