Cryptographic keys are distributed to computer systems to be remotely managed by a management node. First secure channels are established between the management node and trusted computing platforms associated with the computer systems. Cryptographic keys are sent to the trusted computing platforms via the first secure channels, wherein the cryptographic keys are stored in the trusted computing platforms and retrieved from the trusted computing platforms by the computer systems. Second secure channels are established with the computer systems using the retrieved cryptographic keys. Commands are remotely executed on one or more of the computer systems via the second secure channels.
