In El Salvador, there are only three air quality monitoring stations to cover the entire territory of the country. This paper aims to apply Internet of Things (IoT) techniques to design and built a telemetric station for monitoring contamination by particulate matter (PM) in the surrounding environment. The development of this project was based on the IoT Architectural Reference Model: An Esp32 controller as the electronic hardware and Google Suite as IoT platform were used. The main result was an IoT prototype for the measurement of contamination by PM2.5 and PM10 pollutants, which data are accessible from any device with internet access through a website. The developed prototype will be placed in remote stations of the country in order to verify its performance and long-term validation. The new scientific knowledge developed consists of the results obtained from the comparison of the measurements of devices certified by EPA and low-cost electronic sensors, demonstrating their potential in the implementation of new and innovative techniques for the use of hardware and software components are shown in internet of things projects. This knowledge can be applied in fast developments of low-cost and efficient prototypes.","PeriodicalId":309822,"journal":{"name":"2019 MIXDES - 26th International Conference \"Mixed Design of Integrated Circuits and Systems\"","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131588722","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}

It is showed that the fully-passive voltage-mode filter with a fractional-order sub-part can generate interesting dense strange state attractors. Moreover, these attractors are geometrically different from those produced by a similar integer-order mathematical model which is a third-order autonomous deterministic dynamical system. There is strong reason to believe that oscillators provided in this paper belong to the simplest-possible fractional-order chaotic systems. Existence of the structurally stable chaotic attractors is proved by showing plane projections, i.e. oscilloscope screenshots.","PeriodicalId":309822,"journal":{"name":"2019 MIXDES - 26th International Conference \"Mixed Design of Integrated Circuits and Systems\"","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133546716","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, even the most secure cryptographic algorithm may be insufficient, if its implementation does not take into account the threat of information leak through side-channels. Performing an attack on an unsecured device can be very simple and may not require expensive hardware. For this reason research and development of countermeasures against such attacks is very important.This paper presents an environment designed to facilitate research, development and evaluation of countermeasures protecting hardware implementation of cryptographic primitives against side-channel attacks based on power consumption analysis.The environment is composed of hardware cryptographic coprocessor with modular architecture, data transfer and configuration layers and software testbench for design verification. Different crypto primitives (block ciphers, hash functions, checksum) were implemented along with basic countermeasures. Utilized methods of power consumption approximation are also described.Evaluation of capabilities of the entire environment prove that both, hardware architecture and testbench provide easily extensible and versatile framework for research and development of countermeasures against power-based side-channel attacks.","PeriodicalId":309822,"journal":{"name":"2019 MIXDES - 26th International Conference \"Mixed Design of Integrated Circuits and Systems\"","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132357450","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}
