Non-equal-width histogram publishing method based on differential privacy by Lei YANG, Xiao ZHENG, Wei ZHAO

“…Existing histogram publishing technology based on differential privacy may show phenomenon of＆quot;retracting＆quot; and ＆quot;zero bucket＆quot; when histogram is used to reflect the real distribution characteristics of data,and ＆quot;too gentle＆quot; in the case of large data volume.In addition,the existing technology of the original histogram difference of privacy protection when not considering the amount of information of each group is different.In view of the above problems,a kind of non-equal-width histogram publishing method based on differential privacy was proposed.First of all,a non-isometric histogram based on the sparseness of the data should bereasonably constructed by empirical distribution function.Secondly,differential privacy protection technology should be applied to non-equal-width histogram to protect the privacy of the original non-equal-width histogram.Finally,the privacy budget should be set for each group according to the class widths of the non-equal-width histogram to improve the privacy of each group of data.The experimental results show that the sparseness of the data distribution is fully taken into account when using the proposed method to perform histogram publishing under differential privacy,effectively avoid the phenomenon of histogram with “retracting” and “zero barrels”,and the accuracy of the published histogram for reflecting the characteristics of the data distribution is guaranteed.Also,when adding noise in line with Laplace mechanism to each group,setting a reasonable privacy budget for each group according to the class widths to some extent increases the privacy of different data segments.…”

Automotive ethernet controller authentication method based on national cryptographic algorithms by Hui GUO, Yong LUO, Xiaolu GUO

“…With the development of intelligent and connected cars, cyber security of automotive ethernet becomes the focus of automotive industry.Authentication is one of the key technologies for automotive ethernet security.The existing authentication methods have shortcomings to meet the requirements of both safety and electronic controllers’ performance.Besides, national cryptographic algorithms are becoming a trend for automotive network security, while the related research in automotive ethernet area is still in starting phase.In order to balance the limited computing performance of electronic controllers and high security requirements of automotive ethernet, a two-stage trust chain authentication method based on national cryptographic algorithms was proposed.The method can be used in different automotive ethernet topologies.A trust chain was built up based on authentication credentials, which linked the two authentication stages, namely the initial stage and the vehicle using stage.The initial stage was triggered by diagnosis instrument at end of line or controller replacement.It deployed complete authentication based on SM2 algorithm and certificates in the initial stage.The vehicle using stage was triggered by ethernet gateway at vehicle power-on or network wakeup.In this stage, the method deployed fast authentication based on SM4 algorithm and authentication credential trust chain.The authentication credentials for trust chain were generated by credential functions.In order to ensure security, each credential was generated based on last successful authentication parameters dynamically.The test results on automotive ethernet controllers show that the method has lower computing cost and higher security level, and it can guarantee both performance and security.…”
