Summary:Techniques for real-time updating of encryption keys are disclosed. In the illustrative embodiment, an encrypted link is established between a local and remote processor over a point-to-point interconnect. The encrypted link is operated for some time until the encryption key should be updated. The local processor sends a key update message to the remote processor notifying the remote processor of the change. The remote processor prepares for the change and sends a key update confirmation message to the local processor. The local processor then sends a key switch message to the remote processor. The local processor pauses transmission of encrypted message while the remote processor completes use of the encrypted message. After a pause, the local processor continues sending encrypted messages with the updated encryption key.
