BS EN 726-7:1999

This part of EN 726 specifies:

• the minimum security requirements for a Security Module (SM)
• the general card related functions embedded in the SM±terminal protocols including minimum data exchange; The data elements and cryptographic processing described in annex A for the case where the SM is an ICC should be supported if the SM is not an ICC or the configuration of the system, e.g. where the SM handles more than one terminal/user card. Configurations where the SM handles more than one terminal/user card are not fully specified in this standard. Further mechanisms may be required to enable these configurations
• the necessary security services and mechanisms to provide application and cryptographic security information for the processing of telecommunication transactions.
