Multi-Application Functionality
my-d vicinity provides the possibility to use one large sector or several smaller ones with different
sizes.
Optionally, one sector can be opened without authentication to read e.g. additional label and issuer
information.
Thus, my-d vicinity meets the need of low cost memory applications like public transport as well as
the more extensive needs of payment systems, which is also supported by the counter function.
Two different key sets for each memory sector support systems using key hierarchies.
System Security
In the system design, special emphasis has been placed on security against fraud.
The serial number is unique for each label and can not be changed. Access to the protected
memory of the label is only possible after a mutual authentication (challenge/response) which is a
function of the unique serial number, random number and key to be used. Authentication is only
possible with a security access module, SAM, that holds the algorithm.
Therefore, for all operations on the protected memory, the SAM calculates and checks by a
message authentication code (MAC) the integrity of the transferred data. Thus, operations on the
protected memory are key protected, and restricted by page-configurable access conditions.
