The data exchanged within the wireless sensor network often contains the information important to save the human lives, e.g. vital parameters of the firefighters during an action. The crucial issue here is that these data cannot be tampered or lost, thus the communication needs to be secured and resilient. Securing the data transmission within the sensor network has to take the constraints of the wireless sensor networks into consideration. The data resilience can be achieved by applying data redundancy supporting data storage or a distributed shared memory in the sensor network, also taking the network constraints into consideration. A distributed shared memory middleware provides means for data replication and sharing between the nodes in the sensor network. The data redundancy helps to reach the goal of a highly dependable network. Our proposal allows protecting the data within the distributed shared memory by using lightweight cryptography. Applying the lightweight cryptography reduces the time of the computations performed on the sensor nodes, what speeds up the delivery of the critical data to the control centers for example. Since the security related issues are an essential prerequisite for network dependability, providing a configurable and secured distributed shared memory is a very interesting topic.
