Abstract
First of all, we propose a light-weight and scalable broadcast authentication scheme for sensor network. Because of the schema of the scheme being similar to window curtains, we choose Curtain as the name of this scheme. Instead of using Merkle tree to combine multiple μTESLA instance, we apply compressed Bloom filters to multiple μTESLA. Our scheme can support longer duration and prolong the self-healing property. We greatly reduce the communication overhead at the cost of allocating a moderate space in each receiver. Combing with PKC computation like ECC, our scheme can guarantee the long-term security and also mitigate energy consumption. Moreover, we substituted counting Bloom filters for compressed Bloom filters. The extended Curtain will be applicable for the situation of multiple senders, offering efficient user addition and revocation.
