However, the behavior of website registration has not ever been thoroughly studied. We use the database provided by the Chinese Software Develop Net (CSDN) to provide a complete perspective on this research point. We concentrate on the following three aspects: complexity, correlation, and preference. From these analyses, we draw the following conclusions: firstly, a considerable number of users have not realized the importance of identification and are using very simple identifications that can be attacked very easily. Secondly, there is a strong complexity correlation among the three parts of identification. Thirdly, the top three passwords that users like are 123456789, 12345678 and 11111111, and the top three email providers that they prefer are NETEASE, qq and sina. Further, we provide some suggestions to improve the quality of user passwords.展开更多

To meet the requirements of the new Internet environment and eliminate the shortcomings of the existing network, integrated network is presented. In the naming system part, a system based on Chord algorithm was used, and multi-path is introduced to improve the name resolution reliability. In this paper, we mainly pay attention to the reliability model of integrated naming network system which can be attributed as a multi-path transmission issue, and the name resolution paths used in the network path may be cut off by attacks or other events. This paper focuses on parallel multi-path, which is recoverable when failure happens, transmission reliability, and proposes a corresponding reliability model to get the probability of successful transmission in such conditions. Finally, a numerical simulation is devised to demonstrate the multi-path name resolution's high reliability.展开更多
