This paper presents a scheme with which the field device performs message authentication and integrity check only on selected critical packets such that it protects the system operation while avoiding high computation workload, and applies the scheme to a transportation SCADA system. The proposed scheme takes into account of the SCADA computation power limitation and real time requirements, and the extreme difficulty of making any changes to hardware or software in the legacy system. AES-CCM and symmetric key methods are applied for providing message authentication and integrity, and a bump-in-the-wire (BITW) implementation approach is adopted to avoid the changes to the legacy system. This lightweight packet authentication scheme is implemented and demonstrated over a testbed of a metro transportation SCADA system. Experiments show the effects of the scheme in blocking malicious packet attack and the comparison with a firewall approach.","PeriodicalId":320208,"journal":{"name":"2017 23rd Asia-Pacific Conference on Communications (APCC)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129571913","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}

Obfuscation is a technique that modifies some elements of program codes and is used to evade the pattern matching of traditional anti-virus softwares. In particular, encode obfuscation is adopted in almost all malicious JavaScript codes as the most effective technique to hide their malicious intents. Therefore, many approaches focus on encode obfuscation to detect malicious JavaScript. However, we point out that malicious JavaScript obfuscated by the techniques except for encode obfuscation can easily evade those approaches. Motivated by the above, in this paper, we first investigated the malicious files that previous schemes cannot detect, and found that some files contain divided URL in their codes. In order to detect such JavaScript codes as malicious, we propose obfuscated malicious JavaScript detection scheme using the feature based on divided URL. We focus on the fact that the segments of URL are declared as variables and connected later. Our scheme stores variables and their contents in the dictionary type object and in the connection parts, verifies that malicious URL can be reconstructed. By the computer simulation with real dataset, we show that our scheme improves the detection effectiveness of the conventional scheme.","PeriodicalId":320208,"journal":{"name":"2017 23rd Asia-Pacific Conference on Communications (APCC)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116685627","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 used three different methods to investigate the presence and level of support for various Internet protocols. Internet traffic entering and exiting a university network was passively captured, anonymised and analysed to test protocol usage. Active tests probed the Internet's most popular websites and experiments on the default behaviour of popular client, server and mobile operating systems were performed to reconcile the findings of the passive data collection. These results are valuable to research areas, such as those using emulations and simulations, where realism is dependent on the accuracy of the underlying assumptions about Internet traffic. Prior work is leveraged to explore changes and protocol adoption trends. This study shows that the majority of Internet traffic is now encrypted. There has also been an increase in large UDP frames, which we attribute to the Google QUIC protocol. Support for TCP options such as Selective Acknowledgements (SACK) and Maximum Segment Size (MSS) can now be assumed. Explicit Congestion Notification (ECN) usage is still marginal, yet active measurement shows that many servers will support the protocol if requested. Recent IETF standards such as Multipath TCP and TCP Fast Open have small but measurable levels of adoption.","PeriodicalId":320208,"journal":{"name":"2017 23rd Asia-Pacific Conference on Communications (APCC)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126711926","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 ubiquitous visible light communication (VLC) technique has been seamlessly combined into the energy-efficient backscatter communication system, called the visible-light backscatter communication (VL-BackCom), for powering the massive number of IoT devices and prolonging their working-time. In the VL-BackCom system, the tag can modulate and backscatter the visible light signal (by switching the liquid crystal display (LCD) shutter) illuminated from light source to its nearby receiver. However, few work focuses on modeling and analyzing the performance of the large-scale VL-BackCom network. To this end, this paper makes the first attempt to model and investigate the network performance, namely the success VL-BackCom probability and network capacity, by borrowing the analytical tractable tool from stochastic geometry. The network topology is modeled using the analytical tractable generalized Gauss-Poisson process (GPP) under some justifiable assumptions, yielding a lower bound for practical VL-BackCom network with irregular deployment. The expressions of the success VL-BackCom probability and network capacity are clearly derived to characterize the VL-BackCom link's reliability as well as the spatial success transmission density, respectively. Moreover, the effects of backscatter parameters, say duty cycle and reflection coefficient, on network performance are also studied.","PeriodicalId":320208,"journal":{"name":"2017 23rd Asia-Pacific Conference on Communications (APCC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128491835","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}
