Understanding the Shiva Password Authentication Protocol

The Shiva Password Authentication Protocol (SPAP) is the authentication scheme for the Shiva-proprietary connectivity software that supplies client and server operability. If you are using a Shiva client to connect to a Windows RAS server, the server can use SPAP to validate the user’s connection. Be advised that data encryption cannot be used with SPAP. SPAP also provides Windows clients with the capability to connect to Shiva servers.
