Diese Zertifikate werden von Zertifizierungsstellen ausgestellt, und unsere Browser vertrauen diesen Stellen.\n\nWas passiert aber, wenn ein Zertifikat für jemanden ausgestellt wird, der es gar nicht bekommen dürfte? Ist dies bereits passiert?\n\nDer Vortrag geht auf diese Fragestellungen ein und diskutiert, was getan werden kann, um solche Situationen zu verhindern.","original_language":"deu","persons":["Andreas
