It is demonstrated that in the generation phase of user private key, the user identity certificate is transmitted in the public channel, so that the attacker can use the intercepted identity certificate to fake the legitimate node and cheat the distributed key generation center to generate private key for it. Then, an improved authentication scheme is proposed. It constructs the signature of timestamp using the private key of the user node as authentication proof, so that the attacker can't forge the authentication information. It is showed that the improved scheme can effectively resist the forgery attack, and further reduce the computing cost of user nodes while realizing all the functions of the original scheme.","PeriodicalId":373862,"journal":{"name":"2020 IEEE Conference on Telecommunications, Optics and Computer Science (TOCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130412232","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}

This study introduces the long short-term memory (LSTM) neural network to estimate the transient NOx emissions of diesel vehicles. The LSTM deep neural network is used to build the prediction model to ensure the stability as well as the accuracy of the model. The results show that the model has better predictive performance and stability than the two commonly used benchmark models, and the following conclusions are drawn: (1) LSTM has better learning and prediction ability for transient changes in NOx emissions. Compared to prediction with random forest (RF) and support vector regression (SVR), the mean absolute deviation and root mean square error of LSTM are reduced by about 23.6% and 8.3% at least, which also indicated that the input parameters selection method was effective. (2) LSTM is a general estimation approach for time series data, which can reduce the suppression effect of transient data changes on model prediction, and has high prediction accuracy, and can be employed for real road NOx emission analysis.","PeriodicalId":373862,"journal":{"name":"2020 IEEE Conference on Telecommunications, Optics and Computer Science (TOCS)","volume":"275 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124217129","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}

The study found that different regional policy texts have basically the same policy value orientation in terms of service awareness, platform construction, fiscal and taxation policies, etc., while the differentiation level is manifested in incorporating regional resource endowment into the expression of policy texts, thus highlighting advantages and forming social influence.

However, surprisingly, utilizing edge computing and neural networks for facial expression recognition has been neglected for many years, very few research can be found. To be focusing on such topics. In this paper, we improve Visual Geometry Group 19 with the idea of residual learning. To be specific, for each block of Visual Geometry Group 19, we add its input to its output. The result of the addition will be the input of the next block. Then, we minimize the size of our model by pruning and post-training quantization to achieve a higher efficiency and maintain the model's accuracy at the same time when deploying it on edge devices. The experiment result shows that our model has a 98.99% accuracy on the CK+ dataset. Besides, when deploying on edge devices, its inference time is less than many other popular neural networks that are designed for deploying on edge-devices.","PeriodicalId":373862,"journal":{"name":"2020 IEEE Conference on Telecommunications, Optics and Computer Science (TOCS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131308596","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}
