Architecture design of re-configurable convolutional neural network on software definition by Peijie LI, Li ZHANG, Yunfei XIA, Liming XU

“…In order to meet the flexibility and efficiency requirement in convolutional neural network (CNN), an architecture of re-configurable CNN based on software definition was proposed.In the architecture, the process of CNN could be normalized and the operation mode could be accelerated.The calculation pipeline was implemented by using dual bus architecture based on AHB and AXI protocols.By software definition, the proposed architecture, which could realize the real-time processing of data among different CNN structure, was implemented on FPGA.The result shows that at least 2 CNN models can be software defined on the FPGA circuit.The output measures an operation processing capacity of 10 times that of CPU, and an operation energy consumption ratio of 2 times that of GPU.…”

Multi-authority attribute-based encryption with efficient revocation by Kai ZHANG, Jian-feng MA, Hui LI, Jun-wei ZHANG, Tao ZHANG

“…Multi-authority attribute-based encryption was very suitable for data access control in a cloud storage environment.However,efficient user revocation in multi-authority attribute-based encryption remains a challenging problem that prevents it from practical applications.A multi-authority ciphertext-policy attribute-based encryption scheme with efficient revocation was proposed in prime order bilinear groups,and was further proved statically secure and revocable in the random oracle model.Extensive efficiency analysis results indicate that the proposed scheme significantly reduce the computation cost for the users.In addition,the proposed scheme supports large universe and any monotone access structures,which makes it more flexible for practical applications.…”

Optimal Relay Selection Strategy in Cognitive Cooperative Relaying Network by Yinshan Liu, Xiaofeng Zhong, Jing Wang

“…Cognitive cooperative relaying communication significantly improves the performance of wireless communication networks and spectral efficiency.Optimal relay selection problem,which characterize the desired tradeoff between the probing cost for establishing cooperative transmission and hence higher reward via cooperative diversity,is a hard issue when the number of relay nodes is large.Optimal relay selection strategy was established by using optimal stopping theory with a finite horizon.Furthermore,a pure SNR（signal-to-noise ratio）threshold structure was exhibited.Theoretical analysis and numerical results indicate that proposed optimal relay selection strategy is effective in reducing the number of probing candidate relays and improving the reward of source.…”
