Abstract
A device includes a memory to store a session key, a transmitter (TX) physical layer to transmit frames to a second device over a link, and TX datalink logic coupled to the TX physical layer and the memory. To coordinate synchronized encryption over the link with the second device, the TX datalink logic is to cause a key synchronization frame to be transmitted to the second device, wherein the key synchronization frame comprises a frame count value. The TX datalink logic, in response to receipt of a key synchronization acknowledgement from the second device acknowledging receipt of the key synchronization frame, is further to start encrypting frame data with the session key after transmitting a number of frames corresponding to the frame count value.
