Key management is an important issue for wireless sensor networks because sensors have limited resources as memory, processing speed and battery power. Key management is one of the basic building blocks of sensor network security. Many protocol presented before didn't take much attention on mobility of node. In this paper, we proposed Hass Chain based key management scheme for Heterogeneous networks where Base Station and cluster head are fixed and other node moving around these heads. Compare to other basic key management scheme, proposed scheme increase resilience against node capture as well as consider memory limitations. General TermsGeneral terms which are used in this paper are Security, Hash function collision, Hash Chain, Wireless Sensor Network,

“…For WMSNs proposed above, heavyweight computations should be performed by gateways. Furthermore, asymmetric-key solutions are difficult to implement in such a resource-constrained environment, and symmetric-key methods coupled with a priori key distribution schemes would be more appropriate to achieve goals of data secrecy and integrity [10].…”

SUMMARYMultiple hop based routing in homogeneous sensor networks with a single sink suffers performance degradation and severe security threats with the increase of the size of sensor networks. Large-scale sensor networks need to be deployed with multiple powerful nodes as sinks and they should be scheduled to move to different places during the lifetime of the networks. Existing routing mechanisms lack of such supports for large-scale sensor networks. In this paper, we propose a heterogeneous network model where multiple mesh nodes are deployed in a sensor network, and sensed data are collected through two tiers: firstly from a source sensor node to the closest mesh node in a multiple-hop fashion (called sensor routing), and then from the mesh node to the base station through long-distance mesh routing (called mesh routing). Based on this network model, we propose an energy-efficient and secure protocol for the sensor routing that can work well in large-scale sensor networks and resist most of attacks. Experiments demonstrate that our routing protocol significantly reduces average hops for data transmission. Our lightweight security mechanism enables the routing protocol to defend most attacks against sensor networks.

“…Next, a dynamic key management scheme is needed to create new and revoke old or compromised keys. Rigorous work has been published on random pre-deployment of keys [2,5,6,8,10,19] where a limited number of pair-wise or partial keys are randomly assigned to nodes before deployment. In general, the number of necessary pre-deployed keys or partial keys increases with network size [2,5,6,8,10,11].…”

“…Typically, a shared key is used since low complexity and energy requirements of the shared-key encryption schemes. Such a pair-wise key can be either generated from pre-deployed partial keys [2,5], or found among the pre-deployed keys [8,10,11,19], or established through a third party who shares the pair-wise keys with each of the nodes in the pair [2,5,8,10,11,19]. In contrast, the proposed scheme dynamically creates pair-wise keys between neighbor nodes during short initial postdeployment phase.…”

In this paper, an energy-efficient hybrid key management (EHKM) protocol is proposed in which the heterogeneous security requirements of a wireless sensor network are considered to provide differing levels of security with minimum communication overhead. Additionally, it allows the dynamic creation of high security subnetworks within the wireless sensor network and provides subnetworks with a mechanism for dynamically creating a secure key using a novel and dynamic group key management protocol. The proposed energy-efficient protocol utilizes a combination of pre-deployed group keys and initial trustworthiness of nodes to create a level of trust between neighbors in the network. This trust is later used to allow secure communication between neighbors when creating a dynamic, high security subnetwork within the sensor network. This static and dynamic key management combination creates a hybrid key management protocol. Analysis of the proposed protocol with network and cluster sizes and different node failures is performed using the Ns2 network simulator. Additionally, the protocol is compared to other protocols, for example LEAP and a recent dynamic group key management protocol. Additionally, the security of the proposed protocol is analyzed against various attacks by an adversary. Also the overhead due to communication and computation is investigated.
