Abstract:
1. A system, comprising: a client workstation; a single sign-on (“SSO”) server accessible to the client workstation; a plurality of host servers accessible to the client workstation, a unique public key being associated with each host server; wherein access by the client workstation to a first host server causes the client workstation to be automatically re-directed to the SSO server and the SSO server causes the client workstation to request sign-on credentials from a user if the user has not signed on to any of the host servers, and wherein the first host server, not the SSO server, authenticates the user; and wherein said sign-on credentials are used to authenticate the user upon accessing each host server, and wherein said siqn-on credentials are encrypted with the public key associated with the host server for which the sign-on credentials were most recently used to authenticate the user.
