4) Using limited amount of storage devices in the field and public authorities
Within a company every Sales Representative can have his/her own personalised smart
card (own cryptographic keys). For their work every employee receives their own
HS256 S3 which has been priorly initialized. The employee saves the data with his/her
cryptographic keys. After usage the employee gives the HS256 S3 back. Then it goes
through a quick configuration and within minutes it is ready for the next employee.
Therefore there is no need for a HS256 S3 for every employee and the actual amount of
required storage devices is reduced to a minimum.
