Das Password Authentication Protocol (PAP) ist ein Verfahren zur Authentifizierung ΓΌber das Point-to-Point Protocol (PPP) und ist in RFC 1334cite-ref-1[1] beschrieben. Es wurde hΓ€ufig fΓΌr die Einwahl mit Modems zu Netzwerkbetreibern (ISP) verwendet. Heute wird es bei DSL zur Authentifizierung verwendet.
Bei PAP wird das Passwort fΓΌr die Authentifizierung unverschlΓΌsselt zusammen mit der Benutzerkennung ΓΌbertragen. Es ist damit durch passives MithΓΆren ausspΓ€hbar. Dieser unsicheren MΓΆglichkeit steht das komplexere Protokoll CHAP gegenΓΌber. Bei dieser Methode wird mittels Hashing und einer Zufallszahl der Zugang geprΓΌft.
