Privacy-preserving Communication for Vehicular with Multi Receiver Conditionally Anonymous Ring Signcryption
Qian Wang, Mingxing He, Xiao Zheng
In this paper, we propose a privacy preserving protocol based on multi - receiver conditional anonymous ring signcryption. The sender can not only send the same message to the selected multi-receiver and only selected users can correct to decrypt the message, but also receiver reality validate the identity...
Diffusion Model Based on Cellular Automata and Its Application
Jiaoyan Ai, Sizhi Wu, Zongming Wei, Haiyang Xu, Gang Liu
We adopt cellular automata, a kind of complex system modeling method which achieves macro-emergence through local transition rules, to build a diffusion model. We realize parallel computation of the model with MATLAB's matrix processing and develop a GUI for model running. Through adjusting the diffusion...
Research And Implementation of Iterative MapReduce Based On BP Algorithm
Yu Yang, Longjun Zhang
The Error Back Propagation is iterative, the way of implementing it using the iterative MapReduce framework is presented. To solve the shortage of the traditional MapReduce framework in iterative program, the iterative MapReduce framework has added a transmitting module. Through the simulation of the...
