本发明公开了一种无线传感器网络中基于主动探测的抵御黑洞攻击的方法,在网络能量充裕的无线传感器网络远离基站的区域建立多条探测路由,由于攻击者不知道这是探测路由,从而也会发起对这些探测路由的攻击,从而使得攻击者被曝露,这样就能够获得攻击者的行为与位置信息,以及节点的信任度信息。在获得这些信息后,在进行真正的数据路由时可以避开黑洞攻击的区域,就能够在系统的敏感数据没有或者很少损失的情况下获得黑洞的信息,保障无线传感器网络的数据路由安全;充分利用了网络剩余的能量,且能够在提高网络安全的情况下没有降低网络寿命。
A method for defending against black hole attacks based on active detection in a wireless sensor network is disclosed. A plurality of probing routes are established in an area far away from a base station of an energy-abundant wireless sensor network. Since an attacker does not know that this is a probing route, Will launch attacks on these probing routes so that attackers are exposed so that they can obtain attackers’ behavior and location information as well as node trust information. After obtaining this information, the black hole information can be obtained without any black hole attack when the real data routing is carried out, and the black hole information can be obtained with little or no loss of sensitive data to ensure the data routing security of the wireless sensor network. Make full use of the remaining energy of the network, and can not reduce network life while improving network security.
