The triumph of the OTP system to confine host systems is reliant on the non-invertability of the defend hasheesh functions utilize (Carver, 2007). no(prenominal) of the hash algorithms read ever since been wrecked, but it is normally fictional that MD4 is less unfluctuating compared to MD5. If a server supports several hash algorithms, it is only when as protected as the weakest algorithm. there are two methods of profitably and safely executing of OTP points geomorphological tendency of the memento implementation and physical asylum of the tokens. Regarding architecture, the original consideration is attitude of the token in the system. The or so in effect(p) application of OTP tokens is for enter in at work come outs topically or for stretch an indispensable web after a firewall. In an in-house network, whereby all servers are under check up on (distinct from the ease up Internet) an MITM (Man in the Middle) violate is not as apparent (Neuman, 2008). even so SSL entirely cant obstruct a man-in-the-middle assault.
