In this paper, we analyzed security and privacy problems of the current low-cost RFID system, and proposed a new RFID authentication protocol based on security policy. This protocol used these methods like setting tag information permissions according to fields and assigning tags with different privacy levels to prevent the authorized tag`s unauthorized information leakage and protected the user's privacy more effectively. Selective one-way/two-way authentication and interested in information transfer mechanism, which can reduce the communication capacity in the whole process of protocol significantly, enable the certification process more flexible, more specific privacy protection, At the same time, tag can reduce the tag hardware requirements by using XOR operation measures which. The security and energy consumption analysis in this paper proved that this protocol can not only protect the authorized tag`s unauthorized information security more flexible, but also reduce the system hardware requirements and communication volume. Compared with the traditional security authentication protocols, this new protocol is more suitable for low-cost RFID system.

The hybrid wireless-optical broadband access network (WOBAN) is a novel promising hybrid access network. We can improve its performance effectively by improving the wireless network routing algorithm of it. This paper proposes a novel routing algorithm -- the minimum delay routing algorithm (MDRA). In the algorithm, A time delay estimation method is combined with the Dijkstra algorithm used in the routing algorithm for front-end wireless Mesh network (WMN) of WOBAN. Simulation results show that the delay and TDR performances of MDRA are better than that of the minimum hop algorithm (MHRA) in high load conditions in WOBAN.

Standard extended Kalman filtering algorithm usually needs a little precise initial value, but Strap down inertial navigation system(SINS) coarse alignment precision for marching vehicle can't meet the requirement. So UKF (unscented kalman filter) was proposed to achieve SINS initial alignment for marching vehicle with odometer aiding. The state equation for large misalignment error model was expounded, and observation equation was derived when the measurement variable was chosen as difference of velocity offered by SINS and velocity reckoned by odometer. UKF filtering algorithm based on additive noise model was derived. Simulation based on vehicular tests data showed that UKF filtering algorithm could achieve SINS initial alignment for marching vehicle, and UKF filtering algorithm could achieve better robustness from filtering initial value, higher alignment precision and faster convergence velocity than Standard extended Kalman filtering algorithm.

Currently, the functional requirement of optical small satellites is increasing. The operation mode of track stereo imaging is an important one of optical small satellites, which is in the same orbital period, the optical load image the same target area from the front and behind directions to generate stereoscopic image. This requires the small satellites made rapid large angle maneuver with increasing frequency, and have the high precision steady state after the maneuver. Therefore, the requirements of satellite attitude control system are not only a high bandwidth, but also have higher control accuracy. Control moment gyroscope (CMG) is a large torque actuator than the flywheel torque actuator, and it can provide a higher precision control. Application of symmetrical CMGs and flywheel group to control of small satellite attitude, it can achieve fast and high precision attitude motion, and complete the process of track stereo imaging. The joint control of this method needs the switching stability of two kinds of actuators, which means it has to plan and design the actuator torques, such that the effect of switching between CMGs and flywheel is minimal. In this paper, the switching algorithm is designed, which needs to plan the gimbal angular of CMGs, to solve the problem of switching unstable between two kinds of actuators. The Simulation results show that the maneuvering speed is fast, the good stability and smooth switch process of are achieved.
