Overview
Authentication
Authentication verifies the identity of a user or a network device (such as an
APC Network Management Card in the Battery Management System
master controller). Passwords typically identify computer users. However,
for transactions or communications requiring more stringent security
methods on the Internet, the Battery Management System supports more
secure methods of authentication.
• Secure Sockets Layer (SSL), used for secure Web access, uses digital
certificates for authentication. A digital CA root certificate is issued by a
Certificate Authority (CA) as part of a public key infrastructure, and its
digital signature must match the digital signature on a server certificate
on the Management Card.
• Secure SHell (SSH), used for remote terminal access to the Battery
Management System’s control console, uses a public host key for
authentication rather than a digital certificate.
How certificates are used. Most Web browsers, including all browsers
supported by the Battery Management System, contain a set of CA root
certificates from all of the commercial Certificate Authorities.
