A security key infrastructure service request is transmitted from a first application program to a security integration module. In the security integration module, a first policy is requested from a policy server and a first security key infrastructure is selected to service the security key infrastructure service request, according to the first policy. The security key infrastructure service request is transmitted from the security integration module to the selected first security key infrastructure.
