GDL90fuzz: Fuzzing - GDL-90 Data Interface Specification Within Aviation Software and Avionics Devices–A Cybersecurity Pentesting Perspective
2022
As the core part of next-generation air transportation systems, the Automatic Dependent Surveillance-Broadcast (ADS-B) is becoming very popular. However, many (if not most) ADS-B devices and implementations support and rely on Garmin’s GDL-90 protocol for data exchange and encapsulation. In this paper, we research GDL-90 protocol fuzzing options and demonstrate practical Denial-of-Service (DoS) attacks on popular Electronic Flight Bag (EFB) software operating on mobile devices. For this purpose, we specifically configured our own avionics pentesting platform. and targeted the popular Garmin’s GDL-90 protocol as the industry-leading devices operate on it. We captured legitimate traffic from …
Radiation Hardness Assurance Through System-Level Testing: Risk Acceptance, Facility Requirements, Test Methodology, and Data Exploitation
2021
International audience; Functional verification schemes at a level different from component-level testing are emerging as a cost-effective tool for those space systems for which the risk associated with a lower level of assurance can be accepted. Despite the promising potential, system-level radiation testing can be applied to the functional verification of systems under restricted intrinsic boundaries. Most of them are related to the use of hadrons as opposed to heavy ions. Hadrons are preferred for the irradiation of any bulky system, in general, because of their deeper penetration capabilities. General guidelines about the test preparation and procedure for a high-level radiation test ar…
Refining distraction potential testing guidelines by considering differences in glancing behavior
2021
Driver distraction is a recognized cause of traffic accidents. Although the well-known guidelines for measuring distraction of secondary in-car tasks were published by the United States National Highway Traffic Safety Administration (NHTSA) in 2013, studies have raised concerns on the accuracy of the method defined in the guidelines, namely criticizing them for basing the diversity of the driver sample on driver age, and for inconsistent between-group results. In fact, it was recently discovered that the NHTSA driving simulator test is susceptible to rather fortuitous results when the participant sample is randomized. This suggests that the results of said test are highly dependent on the s…
Jääkiekon fyysiset vaatimukset ja pelaajien fyysisten ominaisuuksien testaaminen
2012
Jääkiekko on 80 vuoden aikana vakiinnuttanut paikkansa suomalaisessa urheilukulttuurissa ja luonut moniportaisen sarjajärjestelmän. Jääkiekolle tunnuksenomaisia piirteitä ovat toistuvat luistelupyrähdykset ja voimakkaat kehonkontaktit, mutta varsinaisia lajitaitoja edustavat luistelu, kiekonhallinta, syöttäminen, syötön vastaanotto sekä laukominen. Intervallityyppisen luonteensa vuoksi jääkiekko kuormittaa fysiologisilta osin pääasiassa välittömien energianlähteiden varastoja. Maksimi- ja nopeusvoimaa pidetään tärkeänä yksittäisen pelaajan suorituskyvyn mittarina, aerobisen kunnon osuutta väheksymättä pitkän ottelukauden vuoksi. Luistelu kuormittaa pääasiassa alaraajan suuria lihasryhmiä, k…
Testivetoisen ohjelmistokehityksen hyödyntäminen oliopohjaisessa paradigmassa
2015
Testivetoisen kehityksen (lyhenne TDD) suosio on kasvanut ohjelmistotuotantomaailmassa, ja sen käyttöä suositellaan entistä enemmän. Tutkielmassa on tarkoitus selvittää todelliset vaikutukset testivetoisen kehityksen käytöstä kirjallisuuskatsauksen kautta. Tutkielma keskittyy TDD:n yleisiin hyötyihin ja haittoihin sekä sen vaikutukseen ohjelman sisäiseen ja ulkoiseen laatuun. Tulokset viittaavat siihen, että testivetoisella kehityksellä on sekä hyötyjä että haittoja, mutta lopullinen vaikutelma pysyy positiivisena ristiriitaisista tutkimustuloksista huolimatta. Testivetoinen kehitys paransi selkeästi ohjelmien ulkoista laatua, kun taas vaikutuksia sisäiseen laatuun ei voitu varmuudella tode…
Proton Direct Ionization in Sub-Micron Technologies : Test Methodologies and Modelling
2023
Two different low energy proton (LEP) test methods, one with quasi-monoenergetic and the other with very wide proton beam energy spectra, have been studied. The two test methodologies have been applied to devices that were suggested from prior heavy-ion tests to be sensitive to proton direct ionization (PDI). The advantages and disadvantages of the two test methods are discussed. The test method using quasi-monoenergetic beams requires device preparation and high energy resolution beams, but delivers results that can be interpreted directly and can be used in various soft error rate (SER) calculation methods. The other method, using a heavily degraded high energy proton beam, requires littl…

Tumor-independent Detection of Inherited Mismatch Repair Deficiency for the Diagnosis of Lynch Syndrome with High Specificity and Sensitivity
2023
Lynch syndrome (LS) is the most common hereditary cancer syndrome. Early diagnosis improves prognosis and reduces health care costs, through existing cancer surveillance methods. The problem is finding and diagnosing the cancer predisposing genetic condition. The current workup involves a complex array of tests that combines family cancer history and clinical phenotypes with tumor characteristics and sequencing data, followed by a challenging task to interpret the found variant(s). On the basis of the knowledge that an inherited mismatch repair (MMR) deficiency is a hallmark of LS, we have developed and validated a functional MMR test, DiagMMR, that detects inherited MMR deficiency directly…

Inter‐individual variation of the urinary steroid profiles in Swedish and Norwegian athletes
2020
The steroidal module of the Athlete Biological Passport (ABP) aims to detect doping with endogenous steroids, e.g. testosterone (T), by longitudinally monitoring several biomarkers. These biomarkers are ratios combined of urinary concentrations of testosterone and metabolically related steroids. However, it is evident after five years of monitoring steroid passports, that there are large variations in the steroid ratios complicating its interpretation. In this study, we used over 11 000 urinary steroid profiles from Swedish and Norwegian athletes to determine both the inter‐ and intra‐individual variations of all steroids and ratios in the steroidal passport. Furthermore, we investigated if…
