This paper addresses an interesting security problem in wireless ad hoc network.: the dynamic group k.y agreement k.y establishment. For secure group communication in an ad hoc network. a group k.y shared by all group members is required. This group k.y should be updated when there are membership changes (when the new member joins or current member leaves) in the group. In this paper, we propose a novel, secure, scalable and efficient region-based group k.y agreement protocol for ad hoc network.. This is implemented by a two-level structure and a new scheme of group k.y update. The idea is to divide the group into subgroups, each maintaining its subgroup k.ys using group elliptic curve diffie-hellman (GECDH) Protocol and link. with other subgroups in a tree structure using tree-based group elliptic curve diffie-hellman (TGECDH) protocol. By introducing region-based approach, messages and k.y updates will be limited within subgroup and outer group;hence computation load is distributed to many hosts. Both theoretical analysis and experimental results show that this Region-based k.y agreement protocol performs well for the k.y establishment problem in ad hoc network.in terms of memory cost, computation cost and communication cost.

植物健壮的先决条件,主要取决于根的分布及其活力。因研究根系相当困难,故对根的生长习性的了解比对地上部分的了解少得多。根系具有很重要的生理作用。因为它不仅是大部分绿色植物吸收水分和盐分的部位,而且对植株起着回持作用。在多年生植物中,椰子通年结果,是经济价值最高的棕榈树种之一。因此,了解椰子根的分布、有效根产生最多的部位以及施肥的适宜区等方面的常识十分重要。
