FILE AUTHENTICATION
Introduction to File Authentication
88 VX 675 REFERENCE GUIDE
Figure 27 illustrates the certificate trees in development and deployment
terminals.
Figure 27 Certificate Trees in Development and Deployment Terminals
Permanency of the Certificate Tree
The data contained in a digital certificate is stored in the terminal’s certificate tree
when the certificate is authenticated, and the certificate file itself is erased from
memory.
The certificate tree file is stored in a reserved area of non-volatile memory and is
therefore permanent. New certificate data can be added to the existing certificate
tree (up to a maximum of 21 certificates).
Required Inputs to the File Signing Process
The required inputs to the file signing process are somewhat different for
development terminals than deployment terminals. The significant differences are
shown in Table 9.
