More precisely, a more general fixed-time stability criterion which is available for approximation based control is construct- ed. Combining the fuzzy logic systems with adding one power integrator technique, an adaptive approximation policy is introduced to handle the system uncertainties. Moreover, a novel switching singularity dispelled function is delicately devised to handle the singularity issue in fixed-time control design. As for the input quantization, a variable separable lemma is utilized to extract the quantized signals in a linear-like manner. Numerical and practical simulation example are provided to demonstrate the effectiveness of the designed control scheme.","PeriodicalId":391180,"journal":{"name":"Proceedings of the 2023 4th International Conference on Computing, Networks and Internet of Things","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124402269","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}

Trusted Execution Environments (TEEs) can ensure the security of the code and data running in it. Still, the security of the persistent data needs to be guaranteed by the software in the TEE. This paper presents QuickStorage, a storage system that enables sensitive applications running in TEEs to store data safely and efficiently transparently. QuickStorage draws on the idea of the log-structured storage system. Compared with the previous system, the I/O performance of QuickStorage has been dramatically improved through the new design. We implement QuickStorage on the Intel hardware platform and provide two compaction policies, the classic compaction policy and the leveled compaction policy, for log-structured merge-trees (LSMT) in the index area. We conducted intensive tests on systems using two compaction policies to demonstrate the different advantages of compaction policies. The results show that no matter which LSMT compaction policy is adopted by the storage system, write performance is an order of magnitude improvement compared with the previous storage system. Moreover, the overall read performance is also good. The two compaction policies have various advantages and disadvantages in reading and writing, allowing upper-layer applications to choose a more suitable one to meet their various application scenarios.","PeriodicalId":391180,"journal":{"name":"Proceedings of the 2023 4th International Conference on Computing, Networks and Internet of Things","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132812007","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}

Visual perception plays a crucial role in enabling FAVs to acquire ground information and achieve intelligent capabilities. However, most current FAV vision systems rely on ground processing systems for assistance, which limits their operational range due to communication constraints between the aircraft and the ground. Moreover, the use of vision systems for ground target localization on FAVs is still under-researched. In this work, we present a monocular vision-based on-board ground target recognition and localization system for a self-designed FAV, which can run in quasi-real time, and truly endows the FAV with ground autonomous visual perception capabilities. The system utilizes both the images from camera and attitude-position data of the aircraft, and resolves the issue of temporal mismatch between them. To validate feasibility and accuracy of the system, a series of real-world flight experiments are conducted, followed by a discussion of the errors observed.","PeriodicalId":391180,"journal":{"name":"Proceedings of the 2023 4th International Conference on Computing, Networks and Internet of Things","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132178577","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}

Cognitive radio (CR) is an effective solution to improve the spectrum efficiency of wireless communication, which allows secondary users (SU) to share the spectrum with primary users (PU). In this paper, double-RIS are introduced into the downlink multi-input single-output (MISO) CR system to assist communication. Our design goal is to maximize the sum of the achievable rates of SU and PUs by jointly optimizing the beamforming of cognitive base station and main base station and the reflection coefficients of the double-RIS under the constraints of base station transmission power and interference threshold. In order to achieve this goal, we use semi-positive definite relaxation method (SDR) and alternate optimization method to get the optimal solutions of beamforming vector and reflection coefficient. The simulation results show that in the double-RIS aided CR networks, the proposed scheme can significantly improve the reachable rate of all users.","PeriodicalId":391180,"journal":{"name":"Proceedings of the 2023 4th International Conference on Computing, Networks and Internet of Things","volume":"176 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121216391","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}

Due to the fact that covert timing channels can elude detection by security defence measures, they offer a substantial security risk to the information of Internet users when they are exploited for illicit reasons. The attacker sends at a low rate to ensure the stealthiness of the covert timing channel communication process, making the number of inter-arrival time encoded as covert information much less than the normal number of inter-arrival time, resulting in the low detection accuracy of existing detection methods. In this paper, we propose a covert timing channel detection method based on one-dimensional convolution and self-attention mechanism. The method begins with local feature extraction of the input inter-arrival time sequence by a one-dimensional convolutional layer, then characterizes the correlation between each inter-arrival time by a self-attention mechanism in the encoder, and finally through the full connection layer to produce the type output. In this study, experimental results on a public dataset and 16 self-built datasets demonstrate that the detection method delivers optimal detection results and efficient detection of covert information in low-volume communications.","PeriodicalId":391180,"journal":{"name":"Proceedings of the 2023 4th International Conference on Computing, Networks and Internet of Things","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128612224","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}
