The research conducted and presented here is an original contribution to the development of estimation techniques and mathematical models for measurement oriented purposes regardless of the number of samples in the given period relying on mathematical calculation of the equal complexity as in the methods already in use. The theoretical approach examines the problem of numerical integration focusing on modified Simpson's 1/3 rule and modified Simpson's 3/8 rule used for the purpose of the estimation of the root mean square value when a small number of samples per period is available. It highlights the limitations of Simpson's 1/3 rule and Simpson's 3/8 rule, and shows that the newly proposed algorithm is optimal with respect to measurement accuracy and precision even in cases when the ratio of the sampling frequency and the signal's fundamental frequency is low.

However, GPS Sensors cannot work properly under in-door and underground locations. Therefore, many applications utilize device sensors such as accelerometer, gyrometer, and magnetometer for indoor localization. In this paper, we present a misuse case of how device sensors can be used to exploit the privacy of a user by geo-tracking. We propose an attack model through which the user location can be compromised without using the GPS sensors. The proposed attack model comprises of two stages. The first stage consists of deployment of the malicious application on the users’ smart-phones and gathering the information of various sensors in the background. The collected sensor data is uploaded to the malicious cloud server set up by the adversary. The second stage consists of pre-processing the sensor data received from the malicious cloud server and plot the user’s trajectory onto a graph in real-time. The proposed attack model is evaluated by developing two applications. The victim application tracks location, direction, and trajectory of the user without any location permission from the user. The proposed model achieves an accuracy of 98% without using special infrastructure and separate training phase. Further, we have discussed three mitigation schemes, which can be adapted by the Android developers in order to protect the user’s privacy.</p></div>","PeriodicalId":49815,"journal":{"name":"Microprocessors and Microsystems","volume":"106 ","pages":"Article 105041"},"PeriodicalIF":2.6,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140087111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In principle, depending on the computation workload, individual cores can be turned off to save power during operation. However, too few active cores may lead to computational bottlenecks. In this work, we propose a novel platform named Spike-MCryptCores: a low-power multi-core AES platform with a neuromorphic controller. The proposed Spike-MCryptCores platform is composed of multiple AES cores, each core is equipped with a clock-gating scheme for reducing its power consumption while being idle. To optimize the power consumption of the whole platform, we use a neuromorphic controller. Therefore, a comprehensive framework to generate a data set, train the neural network, and produce hardware configuration for the Spiking Neural Network (SNN), a brain-inspired computing paradigm, is also presented in this paper. Moreover, Spike-MCryptCores integrates the hardware SNN inside its architecture to support low-cost and low-latency adaptations. The results show that implemented SNN controller occupies only 2.3 % of the overall area cost while providing the ability to reduce power consumption significantly. The lightweight SNN controller model is trained and tested with up to 95 % accuracy. The maximum difference between the predicted number of cores and the ideal one from the label is one unit only. Under 24 test scenarios, a SNN controller with clock-gating helps Spike-MCryptCores reducing the power consumption by 48.6 % on the average; by 67 % for the best-case scenario, and by 39 % for the worst-case scenario.</p></div>","PeriodicalId":49815,"journal":{"name":"Microprocessors and Microsystems","volume":"106 ","pages":"Article 105040"},"PeriodicalIF":2.6,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139987897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
