Abstract: A secure Wireless Sensor Network consists of highly secured and trustworthy sensor nodes. But making one single node secure is impossible due to low computational power, memory and cost constraints. Sensor nodes are not tamper proof nor will be in future. In our concept we use low-cost redundant sensors and the Byzantine Fault Tolerance to overcome attacks on the network especially concerning insider attacks. Every sensor node calculates a trust-level of its peer neighbors by a Bayesian probabilistic reputation system. An efficient real-time based communication protocol is used to reduce communication overhead and to transport local trust-levels to the gateway node to calculate a common trust-level.
