ABSTRACT:
A system and method for establishing a mutually authenticated secure link between a mobile platform system and a remote system is provided. An onboard computer system (OCS) generates a dynamic certificate and digitally signs the dynamic certificate with a static certificate. The dynamic certificate is transmitted to a remote central computer system (CCS). The CCS verifies that the dynamic certificate is from a trusted source and sends a return dynamic certificate electronically signed with the static certificate to the OCS. The OCS verifies the return dynamic certificate is from the CCS, thereby establishing a mutually authenticated secure link between the OCS and the CCS.
