We investigate the design space of sensor network broadcast authentication. We show that prior approaches can be organized based on a taxonomy of seven fundamental proprieties, su...
Secure routing in wireless sensor networks (WSN) is a crucial problem that has drawn the attention of researchers. The motivation for tackling this problem comes directly from the...
Architectures that implement the Internet Protocol Security (IPSec) standard have to meet the enormous computing demands of cryptographic algorithms. In addition, IPSec architectu...
In a recent work, we have shown that it is not possible to dependably build any type of distributed f fault or intrusiontolerant system under the asynchronous model. This result f...
