Designing for Smart Cards - Part 2: Practical Implementation


SYSTEM SECURITY

Obviously, access to the smart card should be limited only to authorized users. But, that’s only the first level of security for the total system.

The software should ensure that external, logical addresses aren’t the same as the card’s physical address. This interpretation of logical and physical addresses should be coded into the OS or application software, so an intruder can’t breach the first layer of card security, issue an ISO read command, and access sensitive information.
