Programová výbava pro realizaci útoků postranními kanály

Abstract

Kryptoanalyza postrannich kanalu predstavuje vaznou hrozbu pro mnoho soucasnych kryptosystemu. Utok postrannim kanalem se typicky sklada z aktivni faze, tj. sberu dat, a z analyticke faze, tj. zkoumani a vyhodnocovani dat. V teto praci je predstaven softwarovy balicek, jenz obsahuje podporu pro ovladani kryptografickeho zarizeni, mereni pomoci osciloskopu, (pred)zpracovani dat, statistickou analyzu a pro vyhodnoceni utoku. Balicek je tvoren neinteraktivnimi textovymi aplikacemi s modularni plug-in architekturou, a je uvolnen pod svobodnou licenci.

Side-channel cryptanalysis pose a serious threat to many modern cryptographic systems. Typical side-channel attack consists of an active phase, where data are acquired, and an analytical phase, where the data get examined and evaluated. A software toolkit is presented in this thesis, which includes support for cryptographic device control, oscilloscope data acquisition, data preprocessing, statistical analysis and evaluation of the attack. The toolkit is composed of non-interactive text-based utilities with a modular plug-in architecture, and it is released under open-source licence.
