The proposed method ensured that the individual’s path was smooth and its velocity was continuous. Based on the physiological constraints of humans with maximum velocity and acceleration, time-optimal trajectory and feasible region were derived by solving kinodynamic planning problem. Subsequently, a high-quality trajectory planning algorithm was designed to compute the trajectory with appropriate variation of velocity. The simulation results demonstrate that the proposed trajectory planning method has more authenticities and can generate high-quality trajectories for virtual humans in crowd simulation.展开更多

For power efficient authentication scheme which can provide reliability, efficiency, and security for a general T-MAC communication, a novel synchronization and authentication scheme using authentication masking code was proposed. Authentication data were repeated and masked by PN sequence. The simulation results show that the proposed approach can provide synchronization and authentication simultaneously for nodes in wireless sensor network (WSN). 63 bits AMC code gives above 99.97% synchronization detection and 93.98% authentication data detection probability in BER 0.031 7.展开更多

Source authentication is one of the most needs for many multicast applications transferring real-time information such as stream video and online news. Because multicast current services provided to the group members are changed dynamically, data transferring by a group member is not used by the recipient. In order to verify the identity of the sender who sent the packet and to make sure that the data have not been tampered, an optimized source authentication scheme has been proposed to transfer the authentication information not to the next-door packet. The proposed method for multiple packets authenticates the source with a limited number of electronic signatures. The proposed method can reduce overhead compared to the method by adding a digital signature for every packet. In addition, by sending the generated electronic signature to the first packet and the last packet, it prevents the loss of consecutive packets, as well as a source authentication can be provided in real-time services.展开更多
