Research on scenario-based mechanism in privacy-aware mobile networks
Published 2015-12-01“…The well-developed information services has infiltrated in each part of our daily life,various novel ser-vice modes and applications provide us conveniences at the cost of our privacy.This situation becomes more serious with the increasing number of applications and users’ requirements.The privacy issues of scenario-based mechanism in mobile networks have been studied based on analyzing the state-of-the-art research trends.The threat and chal-lenges of privacy disclosure caused by the mobile network services,and review the scenarios,service models and attack models were introduced firstly.Followed,a comprehensive study on current status of background information,quality of services,and resource-restricted related privacy preservation were made.Finally,some key technologies on privacy preservation such as background information modeling and descripting,multi-background information fusion,quality of services descripting and modeling,self-adaptive methods based on historical information,pri-vacy-preserving solutions optimizing energy resources and privacy-preserving schemes equalizing multiple factors etc were posted.…”

A Universal Calculation Method for Jacobian Matrix of Parallel Mechanism
Published 2015-01-01“…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.…”

Study on the Motion Law of Logarithmic Spiral Type Cam Mechanism
Published 2015-01-01“…The solid models of the logarithmic spiral cam mechanism and common cam mechanism are established by using SolidWorks,and the kinematics simulation is carried out.Then,by using the software of ANSYS / LS-DYNA,the dynamics analysis of the two kinds of cam mechanism is carried out,and the variation situation of the maximum stress of cam mechanism and the follower changing with time is obtained.By contrast analysis between the dynamics simulation and the kinematical simulation of logarithmic spiral cam mechanism and common cam mechanism,find that the logarithmic spiral cam mechanism drive is more steady during the operation,and the force variation and the average stress of cam and follower are lower,which indicates that the logarithmic spiral cam mechanism is superior to common cam mechanism,and possessed of popularization and application value.…”

Conditional privacy-protection remote user authentication mechanism for WBAN
Published 2016-10-01“…A conditional privacy-protection remote user authentication scheme based on a certificateless group signature was proposed,which can accomplish the anonymous mutual authentication between the user and the remote doctors.In addition,when the doctors perceived that users were in case of an emergency,the mechanism enabled the only group manager (GM) to expose the real identity information of users and given users timely assistance.The scheme can provide the anonymity,traceability,mutual authentication,non-reputation and some other security features.The performance analysis results show the scheme is more suitable for WBAN.…”
