Consequently, the greater challenges of encryption efficiency and information leakage facing selective encryption (SE) makes it necessary to reduce the encryption ratio as much as possible. In this paper, we design a SE scheme for H.264/AVC video which achieves a trade-off between low encryption ratio and high safety, for both cryptographic attack and sketch attack point of view. As a starting point, we propose a novel calculation model, called block weight model that can take advantage of reference structure of a video sequence to quantitatively analyze the impact of each block on the motion compensation of other blocks. This calculation model can conduce to accurately select the key bytes in the compressed bitstream for encryption, which greatly retains the network friendliness and improves the efficiency compared to previous work. In addition, our scheme supports scalable encryption granularity by providing an adjustable encryption parameter to meet different security levels. Experimental results verified that our solution is highly efficient in protecting confidential video content with simple computation.","PeriodicalId":244952,"journal":{"name":"2018 IEEE 18th International Conference on Communication Technology (ICCT)","volume":"282 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127554388","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 current research mainly focuses on traffic volume prediction, route recommendation. However, it is also very mea-ningful and instructive to select a suitable less time-consuming alternative route on a specified congested road. In general, skilled taxi drivers who are relatively familiar with the traffic condition would like to choose the less time routes to avoid peak congestion road segments. Inspired by above ideas, in this paper, we propose a novel hybrid framework which integrates both urban traffic flow characteristics theory and machine learning techniques. We first describe the problem definition, then capture a typical set of congestion road features from the GPS trajectories, the features include traffic volume, road speed limit, route distance, traffic light, and weather features. After that, the most commonly used top-k candidate alternate routes based on historical data are generated, then the feature representations for congestion are feed to train the deep learning model, and the best alternative route is selected after the training process. Extensive experiments on realistic datasets derived from realistic car services demonstrate the superiority of our methodologies.","PeriodicalId":244952,"journal":{"name":"2018 IEEE 18th International Conference on Communication Technology (ICCT)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129124333","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, this protocol only considers the number of link hops and is difficult to solve the problem of local network congestion caused by the low-orbit satellite network topology or the uneven distribution of global users. This paper proposes a Link Congestion Oriented Routing Information Protocol (LCO-RIP), which uses link buffer area feedback mechanism and link cost mechanism to distribute the traffic that generates the congested link to other idle link in order to alleviate network congestion and reduce network packet loss. Through simulation and verification, LCO-RIP can significantly reduce packet loss in the network without affecting the average end-to-end delay.","PeriodicalId":244952,"journal":{"name":"2018 IEEE 18th International Conference on Communication Technology (ICCT)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129160345","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}

IQA plays an important role in many image processing applications, such as image enhancement, image compression and reconstruction, watermark addition, etc. In this paper, we present two no-reference image quality assessment (NR-IQA) models based on convolutional neural networks (CNN). One of the biggest challenges in learning NR-IQA model is lack of images with subjective value. Thus, we label images with full-reference (FR) algorithms, the intermediate product “similarity map” is generated when some FR algorithms calculate image quality. We use similarity map or objective score of some FR algorithms to label images separately. The first model uses objective values of SSIM, VIF, GMSD and FSIM respectively, to label images to train the improved VGGNet. The second model uses similarity map generated by FSIM and VSI respectively, to label images to train the improved U-Net. Experiments conducted on the database D215 built in our laboratory show that our second model is comparable to the advanced NR-IQA model.","PeriodicalId":244952,"journal":{"name":"2018 IEEE 18th International Conference on Communication Technology (ICCT)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131085056","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}

Accordingly, the KP q- composite scheme was proposed to tackle this node-capture problem. Recently, Bechkit et al. proposed a hash chain based KP (HCKP) q-composite scheme to further enhance network resiliency against node capture. However, Bechkit et al.'s HCKP q-composite scheme has to perform too many hash operations to establish a secure link between two nodes for the case that the difference of node identifiers is large. This computational overhead is more serious for the large value of q. In this paper, we propose a computational overhead invariant HCKP q-composite scheme by storing one additional hashed value in sensor node. When compared with Bechkit et al.'s HCKP q-composite scheme, the proposed scheme reduces the number of hash operations, and meanwhile the storage overhead remains insignificant.","PeriodicalId":244952,"journal":{"name":"2018 IEEE 18th International Conference on Communication Technology (ICCT)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134206663","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}
