Ab­stract

Wire­less mesh net­works (WMN) are a pro­mi­sing tech­no­lo­gy to es­ta­blish big wire­less net­works with litt­le costs. What we need are se­cu­ri­ty me­cha­nis­ms that per­form well in this spe­cial kind of net­work. The­re­fo­re we pro­po­se the ap­p­li­ca­ti­on of group key agree­ment (GKA) pro­to­cols, since a com­mon en­cryp­ti­on key in the net­work will re­mo­ve the need for reen­cryp­ti­ons and enables a bet­ter per­for­mance.

In this paper, we cont­ri­bu­te a new theo­re­tic ap­proach to me­a­su­re the per­for­mance of cryp­to­gra­phic pro­to­cols in WMN. We de­mons­tra­te the ap­p­lica­bi­li­ty of the new ap­proach with three selec­ted GKA pro­to­cols that have al­re­a­dy been in­ves­ti­ga­ted re­gar­ding their WMN per­for­mance in pre­vious work.
