Research evidence in Cyber-Physical Systems (CPS) shows that the introducedtight coupling of information technology with physical sensing and actuationleads to more vulnerability and security weaknesses. But, the traditionalsecurity protection mechanisms of CPS focus on data encryption while neglectingthe sensors which are vulnerable to attacks in the physical domain.Accordingly, researchers attach utmost importance to the problem of stateestimation in the presence of sensor attacks. In this work, we present SecSens,a novel approach for secure nonlinear state estimation in the presence ofmodeling and measurement noise. SecSens consists of two independent algorithms,namely, SecEKF and SecOPT, which are based on Extended Kalman Filter andMaximum Likelihood Estimation, respectively. We adopt a holistic approach tointroduce security awareness among state estimation algorithms withoutrequiring specialized hardware, or cryptographic techniques. We apply SecSensto securely localize and time synchronize networked mobile devices. SecSensprovides good performance at run-time several order of magnitude faster thanthe state of art solutions under the presence of powerful attacks. Ouralgorithms are evaluated on a testbed with static nodes and a mobile quadrotorall equipped with commercial ultra-wide band wireless devices.
