Availability evaluation method for extended epidemic model and Markov chain based IoT by Xiaotong YE, Wenfei SUN, Shigen SHEN

“…To reflect the availability status of the Internet of things (IoT) under malware diffusion, an availability evaluation method of IoT based on the extended epidemic model SEIRD and Markov chain was proposed.According to actual states of IoT nodes, the classic epidemic model SIR was extended to establish the node state transition model SEIRD.From the dynamic change process of each state of IoT nodes, the dynamic probability equations of IoT nodes belonging to five states were constructed, the Markov matrix reflecting the state transition was obtained, and an availability calculation method of an IoT node was achieved.Taking typical star and cluster IoT topologies as examples, the availability evaluation methods of the whole IoT with different topologies were given.Experiments provide suggestions for administrators how to reasonably deploy the number of normal working nodes and routes.The research results have theoretical significance for improving IoT availability and promoting the successful IoT applications.…”

Research on BER performance of the OAM-SK FSO communication system with wavefront phase correction by Shuang LI, Ping WANG, Tao LIU, Yuting PAN, Wei WANG

“…On the basis of Gerchberg-Saxton (GS) algorithm and angular-spectrum theory, an improved wavefront phase correction algorithm to the Laguerre-Gaussian (LG) beams was proposed for the orbital angular momentum-shift keying (OAM-SK) modulation-based free space optical (FSO) communication system under weak atmospheric turbulence.The light field distributions of the probe beam at transmitter and receiver were regarded as the input of the improved wavefront phase correction algorithm.And the correction phase mask was iteratively calculated to correct the distorted LG beams, thereby alleviating the inter-model crosstalk caused by atmospheric turbulence.Simulation results show that the improved wavefront phase correction algorithm is superior to the conditional GS algorithm.And with the increase of the refractive-index structure parameter, the bit error rate (BER) performance of the OAM-SK FSO communication system is significantly improved.…”

Rule-defect oriented browser XSS filter test method by Zhijie GUI, Hui SHU

“…In order to alleviate XSS (cross-site scripting) attacks,modern browsers use XSS filters for defense.It is difficult to effectively test and evaluate the security of browser XSS filters.The rule-defect is the defect and security problem in the implementation process of browser XSS filter.The formal definition,design test sample and scene generation algorithm were presented for browser XSS filter rule-defects.In order to quantitatively test and evaluate the filtering level of different browser XSS filters,combined with filtering success rate,false positive rate,input loss calculation filtering ability.Based on the proposed method,the prototype system is designed to automate the testing of several mainstream browser XSS filters,and the XSS filtering capabilities of different browsers are obtained.Further,after actual testing,the system also has the ability to discover undisclosed vulnerabilities.…”

Analysis of the Meshing Transmission Characteristic of the Drilling Rig Rotary Table Bevel Gear based on the Virtual Prototyping Technology by Huang Anyi, Dai Yixiang, Hu Xushan, Tian Xiaozhu

“…The drilling rig rotary table bevel gear is an important transmission device for the drive drilling rig.A precise parametric rotary table bevel gear model is established in Pro/E.By means of the data conversion to the interface file parasolid,a virtual prototype model of spiral bevel gear meshing transmission is created in ADAMS.The meshing impact forces of the straight bevel gear are simulated under tow different working conditions.Through analysis,agood coincidence between simulation results and theoretical calculation of the date verified that the virtual prototype model of bevel gears parametric modeling is reasonable and correct.The method provides a theoretical reference for the further discussion of bevel gear transmission system.The accurate simulation result also provides a reasonable guiding for the optimization design of high-power domestic rig rotary table.…”
