Breaking novel and lightweight digital _s ignature scheme by Chun-sheng GU

“…The signature schemes based on RSA and ECC do not seem suitable for special application area such as wire-less sensor network, smart card and wireless RFID since they suffer from low computing efficiency. In order to design a scheme for small computing devices with limited computing capacity, Wang et al. proposed a novel lightweight digital signature scheme based on the hash authentication technology. …”

Compensating Trajectory of a Kind of Long-pitch Constrained Conveyor Chain by Li Shujing, Hong Lin, Liang Yanshu

“…The conveyor chain model which include constrained and free pin is established.Through analyzing each position of pin in static and the movement velocity and displacement of pin in one period are calculated according to its coordinate.The mathematical model of each pin in the state of motion is established and the motion trajectory of free pin should include two parts because of the polygonal action of the chain is proposed.Aiming at the problem of the nonlinear equations in the mathematical model of chain is hard to calculate,a kind of solution method based on fundamental theorem of calculus is presented.Finally,motion trajectory of top and bottom edge free pin is obtained by using the MATLAB point depiction method.A computation method is provided for the analysis of trajectory constrained conveyor chain and the design of constrained trajectory.…”

Compressive sensing based channel estimation for NC-OFDM systems in cognitive radio context by Xue-yun HE, Rong-fang SONG, Ke-qin ZHOU

“…A new channel estimation based on compressive sensing(CS)in non-contiguous orthogonal frequency division multiplexing(NC-OFDM)system was proposed.As for NC-OFDM systems in cognitive radio context,the infrastructure of CS-based channel estimation,the design of pilot patterns and the algorithm of channel estimation were explored.Especially,a criterion of optimizing pilot pattern in the CS-based channel estimation was proposed by minimizing the mutual coherence of the measurement matrix in CS theory.Simulations show that,under many patterns of deactivated subcarriers,CS-based channel estimation obtains much better performance than existing NC-OFDM channel estimation methods in terms of the mean square error of the channel estimate as well as the bit error rate of the system.…”
