Analyzing validation errors of TLS certificates in the wild

Analyzing validation errors of TLS certificates in the wild
Abstract:
Táto práca analyzuje situáciu ohľadom výsledkov validácii certifikačných reťazcov dejúcich sa na Internete. Analýza je založená na reťazcoch zozbieraných z rôznych známych sieťových služieb, a využíva niekoľko kryptografických knižníc na ich validáciu. Výsledky validácie sú skúmané najskôr vzhľadom na ich frekvencie a následne ako n-tice výsledkov z viacerých knižníc na porovnanie správania medzi knižnicami …more
Abstract:
This thesis analyzes the situation about the outcomes of certificate chain validations happening on the Internet. The analysis is based on chains collected for various well-known network services, and it utilizes multiple cryptography libraries for their validation. The validation results are examined first in terms of their frequencies and subsequently as tuples of results from multiple libraries …more
