However, UDP is unreliable, Considerable exploits against UDP-based applications have been discovered in recent years, e.g., DNS cache poisoning, and traffic interception. The essence of these exploits is to inject a malicious UDP segment into the benign data stream, thus poisoning the upper application. After analyzing the typical threats to UDP protocol, we propose a reliable lightweight communication method in this paper, which can verify all segments in a UDP session and mitigate the injection of forged segments from a malicious attacker. The method strengthens the checksum mechanism in UDP protocol and introduces only a few modifications to the UDP specification of end-hosts, without any modification to network devices, i.e., routers or switches. The method preserves the strength of lightweight while improving the reliability of UDP. We implemented the method in Linux 4.14, and the experimental results show that it can mitigate the typical threat to UDP-based applications effectively, meanwhile compared with native UDP, performance loss introduced by our method is less than 2% on average.","PeriodicalId":430931,"journal":{"name":"2019 4th International Conference on System Reliability and Safety (ICSRS)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125467023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this, the finite element model of the 2D model is established using finite element method, and the stress intensity factors of the cracks under various parameters are obtained. The obtained stress intensity factors are polynomially fitted, and the equation for the stress intensity factors of the cracks is finally obtained, which has a good fitting effect and facilitates engineering application and subsequent in-depth study.","PeriodicalId":430931,"journal":{"name":"2019 4th International Conference on System Reliability and Safety (ICSRS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132789020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aimed at the occasion that optimization results would be inaccuracy when the alternative set is chosen improperly through the existing methods, a new optimization method of constant-stress accelerated degradation test with multiple kinds of stresses is proposed. Particle swarm optimization is used to establish an alternative set, and then the simulation data is generated by Monte Carlo simulation. In the entire process of optimization design, two kinds of optimization criteria are adopted to guarantee the comprehensiveness of results. Finally, the optimum accelerated degradation test plan is obtained through the statistical analysis method.

The global sensitivity analysis of a model quantifies the importance of each input parameter to the model output when input parameters have uncertainty. In global sensitivity analysis, unlike local sensitivity analysis, all input factors are varied simultaneously, and as a consequence, one can assess the impact of the higher order interactions among the parameters. In this paper we will use global sensitivity analysis, in particular the Sobol' sensitivity indices, to assess the importance of input parameters in the IEEE 14-bus modified test system. By identifying unimportant input parameters, we will reduce the complexity of the model. We will use randomized quasi-Monte Carlo methods to estimate the sensitivity indices and perform uncertainty quantification for the output of the reduced model.","PeriodicalId":430931,"journal":{"name":"2019 4th International Conference on System Reliability and Safety (ICSRS)","volume":"354 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131811598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, we conducted semi-directive interviews to understand what were the important elements in the composition of a crisis team to better manage the unexpected. It appears that experience takes precedence over the hierarchical level of the involved individuals. It even seems preferable not to involve or at least to limit the number of members of the upper management. Although our study shows the benefits of simulations, stress test scenarios, the composition of the crisis team has to be better integrated especially to take into account emerging risks such as cyberattacks where improvisation plays a crucial role.","PeriodicalId":430931,"journal":{"name":"2019 4th International Conference on System Reliability and Safety (ICSRS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131351804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, they complicate the line's protection due to impedance change of the line, voltage inversion, current inversion and sub-synchronous oscillation. Distance and differential protections are used in different arrangements in transmission line protection. Often they are used together as main and backup protection. In this paper, the fault tree method is used to compare the reliability of three common transmission line protection schemes. The schemes considered here are distance (main)-distance (backup) $(Z, Z)$. differential (main)-distance (backup) $(Delta, Z)$ and differential (main)-differential (backup) $(Delta, Delta)$. Fault trees are used to calculate the reliability of protection schemes in terms of both unavailability and failure rate. The analyses show that, for series compensated lines, using distance protection reduces protection system reliability. Differential protection performs best in terms of reliability despite depending entirely on communication.","PeriodicalId":430931,"journal":{"name":"2019 4th International Conference on System Reliability and Safety (ICSRS)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131382376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, another collision avoidance manoeuver, which is speed reduction, was incorporated into the model and was combined with course alteration by fuzzy logic. For validating the effectiveness, the AIS data of Northern Yellow Sea were used for experiments. The results showed that the collision risk between ships can be effectively represented by the proposed model. In addition, the advantage of the proposed model was verified by comparing with the danger sector model.
