Finally, taking the display function of the IMA system as an example, the DTFA is used to decompose the failure mode of the display function of the IMA system, and the reliability EDSPN model of the multi-partition software of the display function of the IMA system is established. Using TimeNET4.4 simulation software to perform transient analysis and steady-state analysis on the model, the failure rate of the display function of the IMA system is 7.8×10−5, and the influence of the fault propagation rate between the partition software on the display function of the IMA system is obtained. A good model foundation for reliability analysis of IMA system multi-partition software is provided.","PeriodicalId":376290,"journal":{"name":"2021 IEEE 6th International Conference on Computer and Communication Systems (ICCCS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128584148","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}

Based on the Internet of Things(IoT) technology, an open field smart planting system is designed. STM32 microprocessor is used as the main control chip to design terminal nodes. Each node has the ability to sense the air temperature and humidity, soil humidity, light intensity and other planting environment parameters, and has on-off control function for irrigation and plastic film device. The number of terminal nodes can be increased or decreased to meet the needs of open field smart planting. The terminal node connects the NB-IoT base station through NB-IoT module, and then transmits the sensing data to the cloud server. We can monitor the plants, the planting environment and the working states of the device by the 5G wireless cameral. The user terminal is a smartphone. User can log in to the open field smart planting system through mobile APP, and then interact with the terminal device, monitor the sensing data in real time, watch videos of plant growth status and planting environment, and control the irrigation and plastic film devices remotely. It can also be set to automatic control mode to control the devices automatically. The system has the advantages of simple architecture, convenient deployment and use. The rented cloud server is used for data storage and data processing. Data is transmitted through services provided by operators. It is safe and reliable with low operation and maintenance cost, and is suitable for open field planting of family farm.","PeriodicalId":376290,"journal":{"name":"2021 IEEE 6th International Conference on Computer and Communication Systems (ICCCS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132113399","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, lack of efficiency and existing the problem of large ciphertext expansion rate are the main disadvantages impede the applications of this mechanism. Thus, we propose an efficient and practical ciphertext policy attribute-based encryption (CP-ABE) scheme from lattices in the paper. In this scheme, to make the secret key reusable, we adjust access tree and propose a basic access tree structure, which can be converted from disjunctive normal form, and combine it with a light post-quantum scheme of Kyber. In addition, the compression method and plaintext expansion method are introduced to optimize the scheme. Our CP-ABE scheme is secure against chosen plaintext attack under the hardness of module learning with errors problem. We implement our scheme and compare it with three recent related schemes in terms of security, function and communication cost. Experiments and comparisons show that our CP-ABE scheme has advantages in high encryption efficiency, small matrix dimension, small key sizes, and low ciphertext expansion rate, which has some merit in practice.","PeriodicalId":376290,"journal":{"name":"2021 IEEE 6th International Conference on Computer and Communication Systems (ICCCS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131041205","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 paper proposes an effective broadcast protocol to transfer data in mobile ad hoc networks. The proposed protocol is a network topology awareness based probabilistic broadcast (NTAPB) protocol. It requires each node in the network to be configured with a unique ID. Every time a data packet broadcast from the source node is rebroadcast by another node, the ID of the rebroadcast node is recorded in the rebroadcast record table of the packet header. One packet is only allowed to be rebroadcast by the same node once. The network topology knowledge is dynamically awared by each node according to the information of source node and rebroadcast record table carried in the header of the received data packets. The protocol adopts different rebroadcast probability calculation strategies according to different network topologies. It distinguishes network topologies into two categories, fully connected and non-fully connected. For fully connected topologies, it uses a novel mathematical model to solve the optimal rebroadcast probability. For non-fully connected topologies, it distinguishes egress nodes and non-egress nodes to calculate rebroadcast probability separately. Different from related literature that only carried out simulation experiment evaluations, the paper has carried out a large number of physical experiment evaluations. The experimental results show that the protocol can obtain satisfactory packet delivery ratio and end-to-end delay under different network topologies.","PeriodicalId":376290,"journal":{"name":"2021 IEEE 6th International Conference on Computer and Communication Systems (ICCCS)","volume":"5 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114389314","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}

Recent studies show that machine learning approaches based on statistical features and raw traffic sessions are effective for this task. However, the performance of the statistical-based approaches largely depends on the quality of the features. Experts need to design different features for different encrypted traffic classification tasks, which is time-consuming. Meanwhile, the raw traffic-based approach needs to uniformize the traffic size; this will cause the loss of information about the overall structure of the network traffic; for example, we do not know the time from the first packet to the last packet in a session. This paper proposes the CENTIME, which can extract comprehensive information based on ResNet and AutoEncoder to identify encrypted traffic. ResNet is used to extract information from uniformized traffic, and AutoEncoder is used to encode statistical features. The statistical features are used to compensate for the information loss caused by traffic uniformization. They only need to be designed once rather than be designed separately for different tasks. Moreover, the pooling layers are removed, and 1D convolution layers are used to help CENTIME make more effective use of raw traffic information. We evaluate the CENTIME on the public dataset “ISCX VPN-nonVPN”, and the results demonstrate the CENTIME outperforms the state-of-the-art encrypted traffic classification methods. More importantly, comprehensive traffic features generated in the CENTIME can represent different classes of traffic well.","PeriodicalId":376290,"journal":{"name":"2021 IEEE 6th International Conference on Computer and Communication Systems (ICCCS)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127114718","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}
