1. A system, comprising:
a first bus comprising a first physical transmission medium;
a second bus comprising a second physical transmission medium, the second physical transmission medium being physically separate from the first physical transmission medium;
a first peripheral coupled to the first bus and the second bus, the first peripheral to:
receive a first command from the first bus;
generate a random number responsive to the first command;
generate corruption indication data; and
transmit, via the second bus, the random number and the corruption indication data,
wherein packets of the corruption indication data are randomly interleaved with data packets of the random number; and
a second peripheral coupled to the first bus and the second bus, the second peripheral to access the random number via the second bus and generate a cryptographic key responsive to the random number.
