摘要: At the present time, application of online communication systems are rapidly increasing and most clients depend on a set servers to fulfill their daily needs. In order access these servers, client user needs register each server with different login credentials. To circumvent this situation, concept multi-server authentication has been adopted, where can all using single credential. paper, two-factor protocol, which is proposed by Leu Hsieh, analyzed observed that forgery attack off-line password-guessing be made it. Further, other security threats found in similar kind designed Li et al. This paper mainly focuses enhancing securities previously mentioned protocols thus new protocol. We have employed formal informal analysis analyze The performance our protocol also compared related protocols. It noted accomplishes mutual authentication, session key verification, identity password change phases. Copyright © 2016 John Wiley & Sons, Ltd.
