Tests are usually grouped into test batteries (NIST STS, Diehard,TestU01) to provide more complex randomness analysis. Currently we are focusing on optimization of NIST STS battery.

Currently, we aim to optimize existing Denial of Service attacks (DoS attacks, [[https://en.wikipedia.org/wiki/Denial-of-service_attack|Link]]) in order to achieve maximum impact on the victim webserver. GANet contains source codes we are using - for now, combination of OS apps (Perfmon,...) and Python scripts. * Research project [[research:ganet:main| internal wiki pages]] * Project [[https://github.com/crocs-muni/GANet | Github repository]], [[https://github.com/crocs-muni/GANet/wiki | wiki pages]] **Involved people:** {{:public:crocs:bukac.jpg?50|}} {{:public:crocs:ostadal.jpg?50|}} {{:public:crocs:svenda.jpg?50|}} * [[https://is.muni.cz/auth/osoba/2514|Zdenek Říha]] 2016-now (?) <zriha@fi.muni.cz>; * [[https://is.muni.cz/auth/osoba/172999|Víťa Bukač]] 2014-now (preparation of HTTP DOS experiments, VM preparation, initial Python implementation) * [[https://is.muni.cz/auth/osoba/255508|Radim Ošťádal]] 2014-now (preparation of HTTP DOS experiments) * [[https://is.muni.cz/auth/osoba/4085|Petr Švenda]] 2014-now (gibbering) **Former participants:** Tatevik Baghdasaryan 2014-2015 (testing simple web server); ** Selected publications ** * [2015] {{:public:research:ganet_paper1.pdf|Bukač, V.; Ošťádal, R.; Švenda, P.; Baghdasaryan, T. and Matyáš, V.: Challenges of fiction in network security - perspective of virtualized environments}}, LNCS 9379, pp. 145-151, Springer, 2015. * [2014] {{:public:research:redqueensrace_aptwinwingame.pdf|Bukač, V.; Lorenc, V. and Matyáš, V.: Red Queen's Race: APT win-win game.

The Android APK files are digitally signed, but the signer can be anybody. Therefore it is possible to to modify the APK files (to include malware, for example) and resign it. This can be done in an automated way. Such a modification/infection can also be done online in the form of the man-in-the-middle attack where the APK package is transparently modified on its way from the server towards the mobile device if no encryption of the communication is done. **Involved people:** {{:public:crocs:zriha.jpg?50|}} {{:public:crocs:klinec.jpg?50|}} * [[https://is.muni.cz/auth/osoba/2514|Zdenek Říha]] 2012-now * [[https://is.muni.cz/auth/osoba/ph4r05|Dušan Klinec]] 2014-now **Former participants:** Jan Svoboda (2013-2014), Eduard Cihuňka (2013-2014) ** Selected publications ** * [2014] [[http://is.muni.cz/th/374288/fi_b?info=1|E.
