Automatic verification of software packages with help of DNS
Sehnoutka, Martin ; Dvořák, Jan (oponent) ; Jeřábek, Jan (vedoucí práce)
This master’s thesis deals with the problem of secure software distribution. An enhancement for the current state is proposed with the help of the domain name system which is used as a storage for verification keys. These keys are necessary for integrity verification of packages downloaded using a package manager. Furthermore, an extended version is proposed, which takes into account also repository metadata. Both versions are implemented using the Python programming language and integrated into the dnf package manager. This implementation is then tested in a virtual environment, discussed and evaluated in terms of its performance.

Unified Software Database for RPM Based Systems
Šilhan, Jan ; Očenášek, Pavel (oponent) ; Zelený, Jan (vedoucí práce)
In GNU/Linux environment there are many ways of installing software. At this moment we have multiple tools for managing some specific parts of the system that overlap each other. Linux distributions have main package management system and the popular programming languages have also its own package manager. These all have to keep track of installed software. Thus every package manager maintains its own private database with redundant package metadata. The motivation of this thesis is to analyze storages and identify common use cases of package managers on Fedora distribution; design and implement one central Unified Software Database on the system where all information about packages could be stored.
