USER’S GUIDE AUTOMATIC TRANSFER SWITCH
131
– The length of the public key (RSA key) that is used for setting up an
SSL session is 1024 bits, providing more complex encryption and
consequently a higher level of security than the public key used in
Method 1. (This longer encryption key is also used in Method 2.)
– The server certificate that you upload to the Automatic Transfer
Switch enables SSL to authenticate that data are being received
from and sent to the correct Automatic Transfer Switch. This
provides an extra level of security beyond the encryption of the user
name, password, and transmitted data.
– The browser matches the digital signature on the server certificate
that you uploaded to the Automatic Transfer Switch with the
signature on the CA root certificate that is already in the browser’s
certificate cache to provide additional protection from unauthorized
access.
• Disadvantages:
– Setup requires the extra step of requesting a signed root certificate
from a Certificate Authority.
– An external Certificate Authority may charge a fee for providing
signed certificates.
