Ad-hoc网络节点之间的无线连接越多,网络通信跳数相对越少,但网络需要的密钥量越大,加重了密钥维护的负担,因此在通信跳数可接受的情况下应该尽量减少密钥量。定义了网络付出的代价,用来描述通信跳数和密钥量。以网络付出的代价最小为原则,设计了一种简单的密钥维护优化方案。将方案应用于一个Ad-hoc场景,推算结果表明该方案对密钥维护的优化是有效的。
The more wireless connections between Ad-hoc network nodes, the fewer network communication hops, but the greater the amount of keys required by the network, which adds to the burden of key maintenance. Therefore, when the number of hops is acceptable, Minimize the amount of keys. Defined the cost of the network, used to describe the communication hops and key volume. With the principle of minimizing the cost of network, a simple key maintenance optimization scheme is designed. Applying the scheme to an Ad-hoc scenario, the results show that the scheme is effective in optimizing the key maintenance.
