Much of the migrated software is critical to the well-being of the system and users. Thus, methods to produce high quality software are needed. Software development today focuses on taking requirements and producing software as fast as possible. Traditional methods have been augmented or replaced with new, agile methods (like SCRUM) designed to produce bits of code as quickly and cheaply as possible. Unfortunately many of these methods ignore standard testing procedures and rely on reported errors to drive corrections in future releases. Traditional methods require exhaustive testing to eliminate a majority of errors. Both processes are time intensive and in the long run cost the project more to correct errors. This paper demonstrates that errors in requirements and design can be discovered and eliminated prior to implementation with the use of automated theorem provers for formal methods. This illustration is key to saving time and costs in the software development life cycle.","PeriodicalId":306091,"journal":{"name":"2017 IEEE National Aerospace and Electronics Conference (NAECON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132638835","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}

These types of hardware Trojans exploit the empty resources in FPGA by modifying the original design by bitstream modification. In this paper, Trojan Resilient IP is created by adding original design with the dummy logic design in order to provide security and trust for FPGA-based designs. Covering the unused resources with dummy logic design incurs power and delay overhead for FPGA design when the dummy logic circuit is in operation. This paper also addresses the power and delay overhead for Trojan Resilient IP Creation using different ISACS'89 benchmark circuits.","PeriodicalId":306091,"journal":{"name":"2017 IEEE National Aerospace and Electronics Conference (NAECON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115551652","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}

Urbas","doi":"10.1109/NAECON.2017.8268768","DOIUrl":"https://doi.org/10.1109/NAECON.2017.8268768","url":null,"abstract":"In this paper we focus on using signal processing techniques and mathematically-derived photo-detector models, with or without microsphere-lens-enhancement, to analyze, characterize and estimate the effect of integrated aberrations on microsphere-lens-enhanced single photo-detector sensitivity. One of the difficulties here relates to the noisy nature of detector FTIR experimental signals in the MWIR band. We show how modeling of the detector spectral response signal, combined with signal boundary-absorption partial replacement, is successfully effective in estimating integrated detector system aberrations. With the detector FTIR spectral data, considered, our findings show that (a) not all four microsphere materials, considered in this work, namely, Sapphire, SLG (Soda, Lime Glass), PS (Polystyrene) and BTG (Barium Titanate Glass) necessarily result in detector sensitivity increase at all MWIR wavelengths. The PS-microsphere-lens-enhanced detector sensitivity turns out to be less than that of the detector without enhancement in the 2700–3200 wavenumber band. This is due to the fact at this band the PS material exhibits additional significant spectral absorptions. (b) there seems to exist some global detector integrated aberrations introduced by factors such as the microsphere lens material and misalignment, silicone-or-rubber adhesive materiel, photo-detector system and others, that we globally extracted/estimated using the detector experimental FTIR spectral responses and their corresponding generated detector mathematical models. (c) comparison of single detector raw experimental spectral responses (with and without microsphere-lenses of different sizes and material types) to their respective resulting models, shows realistic synthesized detector FTIR data models. With the help of theses resulting detector FTIR response models, we are able to confirm our findings that, relatively independently of the increase in the sensitivity, the microsphere lens significantly decreases the sphere-enhanced-detector Noise to Signal Ratio (NSR), including in spectral bands of high absorption, noise, and aberration. That is, based on the data considered, (1) the resulting microsphere-enhanced photo-detector is generally less sensitive to noise in the MWIR than the mesa and (2) this, seemingly is so, independently of the detector sensitivity increase, for example, due to the microsphere size of a certain material type.","PeriodicalId":306091,"journal":{"name":"2017 IEEE National Aerospace and Electronics Conference (NAECON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121136880","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}

The applications of such protocols fall under numerous categories ranging from internet banking to Internet of Things (IoT). Many standards and developed encryption protocols are available as resources and are used based on the requirements. If the attacker has access to shared keys between devices, it doesn't take long to decrypt the information by using any of the standard encryption algorithms. Therefore, there is a necessity to build strong and complex encryption algorithms. In this paper, we propose a customized encryption algorithm and an authentication scheme to safely transfer information. This algorithm is a variation of Advanced Encryption Standard (AES) and devises a new protocol for key establishment. The implementation of communication protocol between two devices, with a prospect of working with multiple devices using a centralized server is presented. The outcome is to establish a different approach towards encryption and enhance security by providing protection against Man-in-the-Middle attacks. The customized algorithms are implemented using Python.","PeriodicalId":306091,"journal":{"name":"2017 IEEE National Aerospace and Electronics Conference (NAECON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122946953","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}

Taha","doi":"10.1109/NAECON.2017.8268718","DOIUrl":"https://doi.org/10.1109/NAECON.2017.8268718","url":null,"abstract":"In this paper, we present a real-time robust multi-view pedestrian detection and tracking system for video using neural networks which can be used in dynamic environments. The proposed system consists of two phases: multi-view pedestrian detection and tracking. First, pedestrian detection utilizes background subtraction to segment the foreground objects. An adaptive background subtraction method where each of the pixel of input image models as a mixture of Gaussians and uses an on-line approximation to update the model applies to extract the foreground region. The Gaussian distributions are then evaluated to determine which are most likely to result from a background process. This method produces a steady, real-time tracker in indoor and outdoor environment that consistently deals with changes of lighting condition, and long-term scene change. Second, the tracking is performed at two steps: pedestrian classification and tracking of the individual subject. A sliding window technique is used on foreground binary image which uses for determining the input target patches from input frame. The neural networks is applied for classification with PHOG features of the target patches. Finally, a Kalman filter is applied to calculate the subsequent step for tracking that aims at finding the exact position of pedestrians in an input video frames. The experimental result shows that the proposed approach yields promising performance on multi-view pedestrian detection and tracking on different benchmark datasets.","PeriodicalId":306091,"journal":{"name":"2017 IEEE National Aerospace and Electronics Conference (NAECON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128282546","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}
