Adaptively secure key-policy ABE scheme with fast decryption by Qi LI, Jian-feng MA, Jin-bo XIONG, Xi-meng LIU

“…In the existing adaptively secure ABE (attribute-based encryption) schemes,the decryption cost goes linearly with the number of attributes that are used in decryption.An adaptively secure key-policy ABE (FKP-ABE) scheme with fast decryption is proposed,where constant size of computation overhead is implemented in decryption.This scheme is constructed on composite order bilinear groups and supports any monotonic access structure that can be expressed by LSSS (linear secret sharing schemes).The proposed scheme is proved to be adaptively secure in the standard model.…”

Bogdanov-Takens bifurcations in the enzyme-catalyzed reaction comprising a branched network by Qiuyan Zhang, Lingling Liu, Weinian Zhang

“…In this paper we give conditions for the existence of a cusp and compute the parameter curves for the Bogdanov-Takens bifurcation, which induces the appearance of homoclinic orbits and periodic orbits, indicating the tendency to steady-states or a rise of periodic oscillations for the concentrations of the substrate and the product.…”

Research on parallel partheno genetic algorithm based on the immune programming by XING Xiao-shuai, HUO Bing-peng

“…A novel algorithm parallel partheno genetic algorithm based on the immune programming（IPPPGA） was proposed,the algorithm analogies to the concept and theory of immunity in biotic science and unifies the parallel compu-tation thought,after analyzing the advantages and disadvantages of the partheno genetic algorithm.The theory analysis and experimental results show that the algorithm not only effectively keeps population diversity,but also alleviates the undulate phenomenon in evolutionary latter stages,meanwhile increases the convergent speed and computational effi-ciency greatly.…”

Research on estimating effective order of radio channel in OFDM systems by LI Guo-song, ZHOU Zheng-ou

“…In wireless communication system based on OFDM,the character of LS algorithm’s result in time-domain was paid much attention to.At the same time,the character of Channel Impulse Response（CIR）in time-domain was taken into account.It was proposed to detect energy of CIR’s tap of LS algorithm’s result in time-domain and search the effective order of radio channel conversely.By theoretical analyses and computer simulation,it is indicated that this method shows good performance in estimating effective order of radio channel.…”
