Secure storing of encryption and authentication keys

This bachelors thesis is focused on analysis of possibilities of secure storing encryption and cryptographic keys in computers and internet of things devices. It also describes the functionality and level of cryptographic security of chosen solutions and points at possible security vulnerabilities. Next part of the thesis consists of results of test of block cyphers on different architectures. Best of them were chosen as a base for custom solution for secure storing encryption and cryptographic keys. The designs were implemented in form of console application for computers and universal Windows platform application for IoT devices, that includes information about computing power needed to use the proposed solution. At last we conducted vulnerability analysis and evaluated their cryptographic security
