Abstract
An authentication system comprises a plurality of servers storing respective shares of a private key, and a controller associated with the servers. The authentication system is configured to receive a message comprising a password encrypted using a public key corresponding to the private key. The controller directs performance of distributed password-based authentication in the authentication system based at least in part on the encrypted password utilizing the shares of the private key stored in the respective servers. The message is formatted in a manner consistent with an authentication protocol that normally utilizes public key signatures as a mechanism for authentication but is modified to support password-based authentication. For example, the message may be formatted in a manner consistent with a request message of a Kerberos PKINIT protocol extension.
