It helps learners can access virtual laboratories through web interfaces without any geolocation restriction, especially in the Covid-19 pandemic. Furthermore, instructors can monitor and understand learners' behaviors in practice sessions by analyzing actions and logs from the virtual platform. But, to realize this feature, such a platform must gather data during cybersecurity training for data mining tasks. In this paper, we introduce a virtual laboratory platform to facilitate cybersecurity training courses, namely vLab. In addition, we apply clustering analysis to the actions of learners to better understand the capabilities of trainees in resolving given challenges in digital forensics subject. With the built-in behavior analyzer in vLab, instructors can find out the common mistakes, and the reasons for learners' failure results, or identify whether they actually conduct experiments to get answers for digital forensics challenges or not.","PeriodicalId":135827,"journal":{"name":"2022 International Conference on Advanced Technologies for Communications (ATC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129386001","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}

Recently, Video Multimethod Assessment Fusion (VMAF) is developed by Netflix, known as a full refence VQA model that combines spatial and temporal features to predict perceptual quality. This metric has stronger correlation with human visual system than the conventional metrics such as Peak Signal to Noise Ratio (PSNR) and Structure Similarity Index (SSIM). However, the perceptual video quality is normally degraded due to the content and bitrate variation. This leads to uncomfortable experience for the viewers. In this context, this paper proposes an adaptive quantization parameter (QP) prediction model based on VMAF for video coding to achieve better perceptual quality at a reasonable bitrate. In particular, the Rate Distortion Optimization (RDO) progress of x.264 video codec is improved by using the VMAF scores to find optimal QP map. The results showed that the compression performance of x.264 codec with the proposed method achieved up to 5.95% bitrate saving when compared to the conventional x.264 encoder.","PeriodicalId":135827,"journal":{"name":"2022 International Conference on Advanced Technologies for Communications (ATC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115446466","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}

{"title":"Multi-Certified Root-of-Trust: Exploiting Synergies","authors":"S. Guilley","doi":"10.1109/atc55345.2022.9942989","DOIUrl":"https://doi.org/10.1109/atc55345.2022.9942989","url":null,"abstract":"In recent years, worldwide chip production has increased significantly. The “back to silicon” trend is driven by the digitization of multiple usages as well as the specificities of certain markets. As chips are liable for data protection, the proportion of chips with embedded security features is increasing. Because of the shortened time-to-market, some chips must be ready to be deployed in markets or use-cases unknown at the time of design. Since each market has its own security schemes, chips need to be “pre-certifiable” under different schemes. The design activity is usually tailored to a given set of security requirements. In the new context where multiple requirements will have to be satisfied proactively, design strategies must evolve. In this talk, we shall share experience regarding the design of chips eligible to triple precertification, namely: Common Criteria (CC), NIST FIPS 140 and Chinese OSCCA. The synergies arise at three levels. First, documentation production is rationalized. Typically, in the latest version of FIPS 140 (version 3), lifecycle assurance requirements can be mutualized with the ADV, AGD, ALC and ATE assurance classes in CC. Second, it is often beneficial to combine functional requirements. Consider, for example, the mandatory self-checks of cryptographic algorithms and/or keys in FIPS 140: these are sound precautions that reduce the number of vulnerabilities in the CC context. Third, some specific IPs need to be analyzed more deeply in all the schemes anyhow. For instance, regarding True Random Number Generators (TRNGs), there are very detailed, even intrusive requirements (e.g., access to “raw” bits). Similarly, the standards require testing on millions of bits generated in a row by the TRNG. The OSCCA scheme requires that several TRNG rationales be implemented, so as to withstand total failures. Obviously, this also benefits the resistance to fault attacks under a CC prism. However, it should be noted that some pitfalls should also be avoided. For example, EVITA's secure boot is based on firmware hash, which is incompatible with FIPS 140-3 requirements to leverage the digital signature (from level 3 onward). To sum up, we intend to show that certification efforts can be rationalized to better reach the market, with cost-saving factorization while designing or producing certification-related evidence sets.","PeriodicalId":135827,"journal":{"name":"2022 International Conference on Advanced Technologies for Communications (ATC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116347437","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 writing/reading cost is an important indicator of the efficiency of synthesis and sequencing process. In this paper, we kept the encoding and decoding of LDPC unchanged for fair comparison. However, we propose a binary symmetric erasure channel (BSEC) model for the DNA storage system since substitution and deletion errors occurred during the synthesis and sequencing process. And then, the corresponding log-likelihood ratio (LLR) is calculated by observed error statistics under the BSEC model to achieve the lower reading cost, which is the input of the decoder for low-density parity-check (LDPC) code. Since an exact DNA channel model has not been proposed and the mismatch between the observed and theoretical error statistics, a scaling method for LLR is proposed, which can achieve a lower reading cost for DNA storage. We present the relation between total substitution and deletion error rates and scaling coefficients by curve fitting methods. From the simulation results, we can obtain that the performance of our proposed scheme is equal to or slightly better than that from the conventional scheme.","PeriodicalId":135827,"journal":{"name":"2022 International Conference on Advanced Technologies for Communications (ATC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123809795","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}

Being different from previous research, the reference trajectory is assumed to be the same as the real one. Therefore, the torque at the joints is calculated by using the inverse kinematic and dynamic of the dual-arm robot system. The paper proposes to add a controller when planning optimal trajectory, the torque at the robot joints is calculated from the output of the controller.

Among them, R-peak plays the most important role in diagnosing heart diseases. In this work, we propose an efficient R-peak detection solution that utilizes Butterworth bypass filter, Ensemble Empirical Mode Decomposition (EEMD), and Hilbert Transform (HT) for ECG signals. In our approach, EEMD is employed to extract QRS complexes in ECG signals while Hilbert transform is then applied for obtaining the envelope for the R-peak detection of the ECG signal. Firstly, the baseline wander, artifacts, and noises of raw ECG signals will be removed by using a Butterworth filter. The filtered signal is decomposed into a set of Intrinsic Mode Functions (IMFs), monocomponent signals, by implementing the Ensemble EMD method and the first three IMFs that carry sufficient R-peak information are then combined. After that, the first derivative of the combined signal is calculated to figure out the minima or maxima points and subsequently, the differentiated signal will be transformed to determine the envelope by using HT. Finally, based on that, the maximal positions which describe the R-peak positions are marked. Numerical experiments have been done on a popular public database, MIT-BIH Arrhythmia Database, for verifying the performance of our proposed solution in comparison with conventional algorithms. The obtained results prove that our developed approach outperforms the comparative conventional ones. It achieves the average sensitivity and specificity of 98.74% and 98.71% respectively with a detection error rate of 0.028%.","PeriodicalId":135827,"journal":{"name":"2022 International Conference on Advanced Technologies for Communications (ATC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126859010","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}
