Key Agreement for Heterogeneous Mobile Ad-Hoc Groups∗Key Agreement • October 27th, 2005
In this paper we propose an efficient key agreement pro- tocol suite for heterogeneous mobile ad-hoc groups, whose members use mobile devices with different performance lim- itations, e.g., laptops, PDAs, and mobile phones. Absence of a trusted central authority in ad-hoc groups requires con- tributory computation of the group key by interacting mem- bers. We introduce a performance ratio parameter to quan- tify the performance of a mobile device. Our protocols are based on elliptic curve cryptography (ECC) to achieve bet- ter computation efficiency and are proven secure.
