Abstract

We propose a light-weight and scalable broadcast authentication scheme, Curtain, for sensor network. Instead of using Merkel 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, our methods can be extend to the situation of multiple senders, offering efficient user addition and revocation.
