An Anonymous User Authentication with Key Agreement Scheme Without Pairings for Multiserver Architecture Using SCPKs
With advancement of computer community and widespread dissemination of network applications, users generally need multiple servers to provide different services. Accordingly, the multi-server architecture has been prevalent, and designing a secure and efficient remote user authentication under multi-server architecture becomes a nontrivial challenge. In last decade, various remote user authentication protocols have been put forward to correspond to the multi-server scenario requirements. However, these schemes suffered from certain security problems or their cost consumption exceeded users' own constrained ability.
