To address the issue and establish secure communication, various techniques have been developed. Transmitting secret information in a hidden manner is one of the numerous possible solutions. It can be used to transmit secret information, hidden in other media called cover medium. However, this increases the amount of transmittable data and bandwidth requirements. The work proposed technique is an effort to hide secret information in a cover medium to achieve secure communication, reduce the bandwidth requirement, and ensure the retrieval of secret information in full-strength. The proposed data hiding technique has a high data hiding capacity (HC), provides a high level of security, and results in high-quality stego images. The proposed technique, reversible-enhanced stego block chaining (RESBC), has demonstrated very good results as compared to the state-of-the-art steganography techniques. The RESBC successfully solves the data rate requirement of SBC. It has an improved security level of secret information as compared to the 4-least significant bits (4LSB) steganography. The RESBC has solved the problem of information recovery, associated with ESBC and ensures full health recovery.","PeriodicalId":55287,"journal":{"name":"Canadian Journal of Electrical and Computer Engineering-Revue Canadienne De Genie Electrique et Informatique","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2020-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/CJECE.2019.2938844","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44950005","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}

Although critical path tracing (CPT) is faster than conventional methods, it is not fast enough for fault simulation of complex circuits with a large number of faults and tests. Exact stem analysis is the most important obstacle in accelerating the CPT method. The simplification of stem analysis eliminates time-consuming computations and makes the CPT method more parallelizable. An approximate and bit-parallel CPT algorithm is proposed for ultrafast fault simulation for both stuck-at-fault (SAF) and transition delay fault (TDF) models. Time linearity, speedup, and accuracy of the proposed algorithm are examined and evaluated using ISCAS85, ISCAS89, and ITC99 benchmark circuits. In order to assess the accuracy, the false-positive and false-negative detection of faults are counted for each benchmark circuit. The experimental results reveal considerable speedup as well as acceptable accuracy of the proposed approach in comparison with the traditional methods and commercial fault simulators.","PeriodicalId":55287,"journal":{"name":"Canadian Journal of Electrical and Computer Engineering-Revue Canadienne De Genie Electrique et Informatique","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/CJECE.2019.2950280","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62192949","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}

In 2017, it is estimated that there were around 184 million counterfeit devices, valued at 45.3 billion EUR, 12.9% of total sales. Beyond its economic impact, smartphone counterfeiting affects various aspects of user security and privacy, harms manufacturer reputation, and degrades service quality. Furthermore, since smartphone devices are attached to different mobile networks globally, challenges arise on how devices’ identities are maintained and verified and how the supply chain actors can access the device identity throughout its life cycle with less control from third parties. Decentralized identifiers (DIDs) and verifiable claims implemented on a distributed ledger technology present a powerful candidate to address this challenge. Thanks to Blockchain’s use of cryptographic identifiers, record immutability, and provenance, and the features provided by the DIDs and verifiable claims that enable identity management decentralization, portability, and discoverability. This article proposes a smartphone anticounterfeiting system based on an integrated approach of the technologies mentioned above.

This article describes an original implementation based on a hardware structure used for static and dynamic task scheduling. The proposed custom processor has hardware-implemented RTOS (HW-RTOS) features and is verified using an FPGA circuit. The solution replaces the classical stack save concept with a resource remapping mechanism that enables a new task to be executed starting with the next processor cycle. The proposed hardware scheduler enables unified management of events and interrupts, by implementing a method of attaching interrupts to tasks while ensuring the requirements of real-time systems. The robustness and performance of the proposed platform are guaranteed by the context switch operations, presence of the intertask synchronization and communication mechanisms, and by the efficient use of the multiplexed resources. Instead of saving and restoring general-purpose registers into the memory, the latency is removed by directly commuting the datapath task resources.","PeriodicalId":55287,"journal":{"name":"Canadian Journal of Electrical and Computer Engineering-Revue Canadienne De Genie Electrique et Informatique","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/CJECE.2020.3005360","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62193596","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, these values do not give clear results for different geometries. For this reason, taking into the parameters of the slot geometry accounts for determining the stator and rotor leakage reactance values that are important in terms of obtaining more accurate results. This paper has investigated the stator slot permeance values of nine different stator slot structures commonly used in industrial type of three-phase squirrel cage induction motors for obtaining the best starting torque. The stator inductance and leakage reactance values were calculated for each stator slot structure. The change of starting torque of the induction motor has been analyzed by using the MATLAB code. As a result of the analysis, the stator slot structure, which gives the best starting torque, has been obtained. It has been also shown that a 16% improvement can be achieved by changing the stator slot structure at the starting torque. This increase in the starting torque will provide a great advantage for the motor’s acceleration versus a heavy load.","PeriodicalId":55287,"journal":{"name":"Canadian Journal of Electrical and Computer Engineering-Revue Canadienne De Genie Electrique et Informatique","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/CJECE.2019.2914959","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62193215","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}
