    Security authentication protocol based on elliptic curve cryptography and cookie information for terminal of IoT by Jie ZHAO, Huarong ZHANG

    Published 2016-06-01
    “…For the security problem of terminal devices accessing to the network server in internet of things(IoT),an identity authentication protocol was presented based on elliptic curve cryptography(ECC)and cookie information for internet of things terminal.Firstly,the protocol used user identity information,server private key,random number and expiration time of cookie to form a cookie file.Then,it was encrypted with ECC and stored in the smart terminal.In authentication phase,the mutual authentication was achieved by comparing the security parameters calculated by cookie information.Performance analysis shows that it can resist many kinds of attacks and provide high security,low computation and low communication cost,which was suitable for the terminal devices of limited resources in internet of things.…”

    Analysis of the Mechanics Characteristic and Virtual Prototype of Water-cooled Gearbox in Bell-less Top of Blast Furnace by Xu Mingtao, Liu Fengwei, Zheng Xue, Lu Xianzhong, Chen Manyi

    Published 2015-01-01
    “…The water-cooled gearbox is the key component of bell-less blast furnace top.Its function is to drive and control the rotation and tilt of the material distribution chute to meet the requirements of different material distribution.BY using the virtual prototype technology,taking the water-cooled gearbox of blast furnace as research object and the research of its dynamics simulation is carried out.The simulation results show,either in high or low speed rotation,the meshing force of the outer ring gear is comparatively small.Contrarily,when in tilt,the meshing force of the outer ring gear is comparatively large,the maximum meshing force is nearly 2times of the former,it is show that the distributing device is not very stable when the chute tilting.…”

    Partition detection for large scale ad hoc networks by LI Jian-dong, TIAN Ye, SHENG Min, ZHANG Yan, YAO Jun-liang

    Published 2008-01-01
    “…As the failure of a critical node will directly partition a network,a theorem for critical node identification was proved,which indicates that node degree Ni and elementary loop degree Mi of node i are two decisive factors for the exis-tence of a critical node and shows that Ni-Mi≥ 2 is the necessary and sufficient condition for node i being critical.Based on the theorem,a distributed topology partition detection algorithm(distributed partition detection protocol,DPDP) was presented for large scale networks,which achieves the goal of partition detection efficiently by detecting critical nodes in a local area.Theoretic analysis and experiment results show that DPDP has the advantages of low complexity,high accuracy,low cost as well as good scalability,and is superior to other algorithms.…”
