In this article, we study how to secure distributed filters for linear time-invariant systems with bounded noise under false-data injection attacks. A malicious attacker is able arbitrarily manipulate the observations a time-varying and unknown subset of sensors. We first propose recursive filter consisting two steps at each update. The step employs saturation-like scheme, which gives small gai...

We investigate the problem of distributed sensors’ failure detection in networks with a small number of defective sensors, whose measurements differ significantly from neighboring sensor measurements. Defective sensors are represented by non-zero values in binary sparse signals. We build on the sparse nature of the binary sensor failure signals and propose a new distributed detection algorithm ...
