However, due to reasons such as the low performance of IoT devices, the currently existing security solutions can be hardly applied and even if safe firmware is supplied, security problems may arise due to attacks such as man-in-the-middle attacks and roll-back attacks. To resolve such problems, we propose a new firmware management architecture using blockchains and IPFS (The InterPlanetary File System). Using IPFS can ensure the integrity of the firmware. However, IoT device version management and IPFS URL integrity cannot be guaranteed. Therefore, IoT devices are enabled to be provided with firmware information and updated through blockchian networks to ensure the integrity of the IPFS URL, and an IoT devices management function is provided. The proposed system enables safe firmware distribution and update, and IoT devices' security level is expected to be higher. Through the proposed system, safe firmware distribution and update will become possible and IoT device security levels are expected to be enhanced.","PeriodicalId":226261,"journal":{"name":"2019 21st International Conference on Advanced Communication Technology (ICACT)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131885323","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}

Seo","doi":"10.23919/ICACT.2019.8702015","DOIUrl":"https://doi.org/10.23919/ICACT.2019.8702015","url":null,"abstract":"The development of technology led the cyberspace to be directly connected to the daily life. For a nation, it is essential to collect and analyze the statistics produced from cyber-attack incidents to formulate a policy. Specifically, in the Republic of Korea, the second most cyber-attacked country in the world, the synchronization between the cybersecurity technology and policy is essential. However, in current status, the statistics collected by the government ministries in Korea is varied. For instance, the Ministry of Defense and the Ministry of Science & Technology has a different standard in defining the event and incident and its numbers. Thus, the study aims to propose a standardized concept of cyber incident and event statistics which can provide singularized criteria which can be adopted across the ministerial disciplines. In order to provide aforementioned concept, the authors have posed following research questions. First, how to conceptualize the different types of cyber-attacks into a single standard of reporting cyber incidents? Second, what is the proper definition for cyber incident in both national and international levels of policy dialogue? Third, will the established concept can be proposed as an international standard? The authors first breakdown the scattered conceptual knowledge of cybersecurity by the methodology proposed by Gerring (1999) to provide a better concept which can deliver the better knowledge in cybersecurity policy. After, the authors propose the qualitative method in order to develop the single standard in collecting cyber incident statistics. Finally, the authors leave the possible extensions for future related research area based on the proposed method.","PeriodicalId":226261,"journal":{"name":"2019 21st International Conference on Advanced Communication Technology (ICACT)","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134618645","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}

In order to satisfy the conditions requested by GUM, the authentic reference guide, we have included several statistical calculation steps and printing procedures for the uncertainty report. The program included fundamental steps such as follows; 1) editing steps for mathematical model equation of measurand, 2) steps for standard uncertainty of assigned probability density function (PDF) of each input quantity 3) steps for combined standard uncertainty with uncertainty propagation using partial derivative of each input quantity, 4) steps for extended uncertainty interval with statistical confidence level, 5) printing steps after evaluation and calculating measurement uncertainty. Including these fundamental steps, we included the calculation step of uncertainty which appears in the calibration curve using linear regression method. In the step, the standard uncertainty is calculated in the measurement incorporated by 1st order to 5th order linear regression method. In addition to describing the feature of the program, here, we presented two examples of uncertainty evaluation; one for simple comparison process of measurement, another for including 1st order linear regression process. All the results were confirmed and validated by separate procedure of calculation using Microsoft Excel.","PeriodicalId":226261,"journal":{"name":"2019 21st International Conference on Advanced Communication Technology (ICACT)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132325005","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}

In addition to providing service to local users, the smart terminals utilize unused bandwidth and storage resources to provide proximity services to neighbor terminals in the overlay network. How to ensure the performance of the distributed system with the continuous process of terminals joining or leaving the overlay network (churn) is a crucial issue. Existing strategies maintain the system’s service under churn through the central server scheduling or constructing complex topology. In this paper, we propose a hierarchical topology for terminals network. The inter-cluster and intra-cluster overlay use the unstructured network. The connectivity of topology is easy to be maintained under the churn. Further, we offer a decentralized replications diffusion and maintenance mechanism on the topology. Under the churn of terminals, the number of replications can be maintained autonomously to a reasonable amount. In the ordinary churn, the success rate of services in our network only drops by about 9% and is well kept. The mechanism can also quickly restore the performance of the network under the extremely churn.","PeriodicalId":226261,"journal":{"name":"2019 21st International Conference on Advanced Communication Technology (ICACT)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115529286","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 understanding of the performance of real-time stream data processing technologies has become a key pre-requisite while considering any deployment. Although many technologies for stream data analytics exist, little is known about the impact of writing scripts on their performance. Using a MapReduce programming model on a pseudo cluster, we conduct a word count, experimental evaluation of Apache Storm using five writing scripts; English, Arabic, Hindi, Chinese and Japanese. We define our word count as the number of time a word is written in a body of text. Static and structured data made up of 300 English sentences is translated into the scripts under study and loaded into Apache Storm. The results show that Apache Storm analyzes, English, Arabic and Hindi script sentences with ease as compared to those written in Chinese and Japanese script. Apache Storm also executes and distinguishes individual words and performs a word count on English, Arabic and Hindi sentences faster than those written in Chinese and Japanese. However, in terms of processing, the reverse is true, sentences written in Chinese and Japanese are processed faster than those written in English, Arabic and Hindi scripts.","PeriodicalId":226261,"journal":{"name":"2019 21st International Conference on Advanced Communication Technology (ICACT)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121358214","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}
