ABSTRACT:
An apparatus and method for providing at least one root certificate are disclosed. Specifically, a plurality of root certificates is received and stored. Afterwards, a request is received from a first endpoint device for a desired root certificate, where the desired root certificate is used by the first endpoint device to verify an identity of a second endpoint device. Furthermore, the first endpoint device and the second endpoint device are associated with different certificate hierarchies. The desired root certificate is then sent to at least the first endpoint device.
