Blind recognition of RSC based on logarithmic conformity by Zhaogen ZHONG, Zhaojun WU, Limin ZHANG, Zhiqing WANG

“…A new algorithm based on logarithmic conformity was proposed.Firstly,based on the probability of total RSC coding equation,the concept of logarithmic coincidence degree,which could measure the establishment of coding equation,was introduced.Then because of constraint length of RSC,the polynomial database could be generated,and then logarithmic conformity of every polynomial could be calculated when traversing the database.As the results,the RSC could be recognized,because the correct polynomial could make the conformity maximum.The algorithm has small amount of calculation because of finite traversal,which was only related to amount of intercepted data,besides,this algorithm has good error tolerance by soft decisions.The simulation results show that the correct ratio of recognition can reach 90% at SNR of 0 dB and its performances are obviously superior to those of existing algorithms.…”

Fault tolerance of balanced hypercubes by Xin-xin ZHANG, Li XU, Li-mei LIN

“…Fault tolerance is one of the important ways to measure the reliability of multiprocessor interconnection networks.g-restricted edge connectivity and g-restricted connectivity can ensure every remaining component is disconnected ,the number of neighbors of vertex is no less than g,which can measure the fault tolerance and reliability of multiprocessor and multichannel system more accurately.Balanced hypercubes is a variant of the hypercube,which has some specific topological properties,it can better meet the needs of the multiprocessor system and many new networks.The {1,2}-restricted edge connectivity and the {1,2}-restricted connectivity of balanced hypercubes were proposed,which could enrich the evaluation system of network fault tolerance and reliability in balanced hypercubes topology and it laid a good foundation for the fault diagnosis algorithm of balances hypercube.…”

Efficient signcryption scheme based on Cocks’ identity cryptosystem by Changgen PENG, Xiaoyu ZHANG, Hongfa DING, Shanhui YANG

“…Most of the existing identity-based signcryption schemes are based on bilinear or multilinear pairing operations construction.To solve the problem of low efficiency caused by complex pair operation, a new efficient signcryption scheme based on the identity cryptosystem of Cocks was proposed.Firstly, the security model of the proposed scheme was formalized, and the definition of confidentiality and unforgeability was given.Secondly, the quadratic residue problem was used to realize the concrete construction of the proposed scheme, and the signature algorithm was designed in a logical step by combining Jacobi symbol operation.Finally, the security proofed that the scheme satisfied the confidentiality and unforgeability was given under the random prediction model.The efficiency analysis shows that compared with the existing identity-based signcryption scheme, the proposed scheme greatly improves the computing efficiency and has good characteristics of identity-based cryptosystem.…”

Research on link prediction model based on hierarchical attention mechanism by Xiaojuan ZHAO, Yan JIA, Aiping LI, Kai CHEN

“…In order to solve the problem that the existing graph attention mechanism tends to cause attention distribution to certain relations with high frequency when performing link prediction related tasks, a new link prediction model based on hierarchical attention mechanism was proposed.In the link prediction task, a hierarchical attention mechanism was designed to give different attention to the relationships of different relationship types connected to a given entity in the knowledge graph according to the relationship in the prediction task.While the characteristics of multi-hop neighbor entities were pay attention to, the relationship characteristics was pay more attention to find the relationship type that matches the target relationship.Through comparison experiments with the mainstream models on multiple benchmark data sets, the results show that the performance of the model is better than the mainstream models and has good robustness.…”

Improved method of Tor network flow watermarks based on IPD interval by Jie DU, Yongzhong HE, Ye DU

“…Tor is an anonymous network mechanism that provides services for hiding traffic sources,but it has the problem that the entry traffic flows of Tor are clearly identifiable.Bridge protocols such as obfs4 come into being to solve this problem,which brings new challenges that have not yet been overcome.An IPD interval scheme is proposed,which uses the clustering characteristics of k-means to improve the original scheme,so that the added flow watermark can be detected efficiently in the three modes of obfs4 bridges.The results of experiments show that the improved algorithm has higher detection rate and recognition rate,and has good adaptability to variable netflow traffic,which is conducive to the construction of a nice secure network environment.…”

A Universal Calculation Method for Jacobian Matrix of Parallel Mechanism by Zhang Shuangshuang, Yang Hongtao

“…The Jacobian matrix is a key concept in mechanisms and profoundly reflect the nature of the mechanism,which provides us not only a kinematics mapping relations,it also sets a basis for mechanism analysis and synthesis in the future.A universal calculation method for Jacobian matrix of parallel mechanism is presented based on screw theory.Due to its style of construction,tedious steps in normal calculation method,including observation and derivation are nicely avoided,which makes this new method much more simplified.Meanwhile,since its modularization in style,this method also provides its advantages in computer aided programming.A limited-DOF parallel manipulator 3-RPS is used as an example to testify the superiority of this method,which also set a good foundation for further performance analysis and design.…”
