异构传感器网络中基于随机分散路由的流量与安全
Traffic and Security using Randomized Dispersive Routes in Heterogeneous Sensor Network
摘要：
一般情况下，传感器网络中数据的传输会对流量和网络安全带来很多挑战。现有的方案考虑同构传感器网络，具有较差的性能和可扩展性。由于多对一的流量模式，传感器可以与其邻居的一小部分进行通信。密钥管理是传感器节点保护数据安全的关键过程。大多数现有的方案建立共享密钥的所有传感器，无论他们是否正在通信。因此，它会导致大量的存储开销。传感器网络的另一个问题是由于其无线特性而发生的妥协节点攻击和拒绝服务攻击。现有的多路径路由算法容易受到这些攻击。因此，一旦对手获得了路由算法，它就可以计算出源已知的相同路由，从而危及通过这些路由发送的所有信息。如果攻击者进行节点妥协攻击，他们可以很容易地获得该节点使用的加密/解密密钥，因此他们可以很容易地拦截信息。在本文中，我们提出了一个密钥管理方案，它只建立共享密钥与他们的通信邻居和一种机制，以产生随机的多路径路由安全传输的数据到水槽。在这里，我们采用异构传感器网络，我们正在利用椭圆曲线密码进行有效的密钥管理，这是更有效，可扩展，高度安全，并减少通信开销。由我们的机制产生的路线是高度分散的，节能的，使他们能够以低能量成本绕过背孔。
英文摘要：
Generally traffic and the sensor network security have many challenges in the transmission of data in the network. The existing schemes consider homogeneous sensor networks which have poor performance and scalability. Due to many-to-one traffic pattern, sensors may communicate with small portion of its neighbours. Key management is the critical process in sensor nodes to secure the data. Most existing schemes establish shared keys for all the sensors no matter whether they are communicating or not. Hence it leads to large storage overhead. Another problem in sensor network is compromised node attack and denial of service attack which occurs because of its wireless nature. Existing multi path routing algorithms are vulnerable to these attacks. So once an adversary acquires the routing algorithm, it can compute the same routes known to the source, and hence endanger all information sent over these routes. If an adversary performs node compromise attack, they can easily get the encryption/ decryption keys used by that node and hence they can intercept the information easily. In this paper we are proposing a key management scheme which only establishes shared keys with their communicating neighbour and a mechanism to generate randomized multipath routes for secure transmission of data to the sink. Here we are adopting heterogeneous sensor networks and we are utilizing elliptic curve cryptography for efficient key management which is more efficient, scalable, and highly secure and reduces communication overhead. The routes generated by our mechanism are highly dispersive, energy efficient and making them quite capable of bypassing the back holes at low energy cost.
