FILE AUTHENTICATION
Introduction to File Authentication

Figure 26 illustrates the deployment process.
Figure 26 The Deployment Process
Planning for File
Authentication
File authentication is an integral part of every VX 675 terminal. To safeguard the
terminal’s logical security, the file authentication module requires that any
executable code file must be successfully authenticated before the operating
system allows it to execute on the terminal.

DEVELOPMENT OS SEARCHES FOR A *.*.P7S FILE.
IF A *.*.P7S FILE IS FOUND, OS THEN SEARCHES FOR
A MATCHING APPLICATION FILE.
IF A MATCHING APPLICATION FILE IS FOUND, OS
COMPARES *.*.P7S FILE'S SIGNATURE AGAINST
VALUES IN THE APPLICATION FILE'S CALCULATED
SIGNATURE.
IF THE VALUES MATCH, THE TWO FILES ARE
AUTHENTICATED, AND THE ATTR_NOT_AUTH BIT
IS SET TO 0.
