1. An aircraft sensor network on an aircraft, the aircraft sensor network comprising:
a plurality of wireless nodes located on at least one landing gear of the aircraft;
wherein a first wireless node of the plurality of wireless nodes is arranged to receive, over a first communications channel, from a remote computing device outside of and separate from the aircraft and the aircraft sensor network, at least one replacement cryptographic key and at least one control message to replace a current cryptographic key currently in use to secure communications transmitted over a secure second communications channel between the wireless nodes in the aircraft sensor network, and to communicate the at least one replacement cryptographic key to a second wireless node of the plurality of wireless nodes via the secure second communications channel which is different from the first communications channel,
wherein the second wireless node is arranged to perform at least one operation based on the at least one control message, wherein the at least one operation includes a configuration operation to replace the current cryptographic key with the at least one replacement cryptographic key,
wherein the first communications channel is a short-range wireless communications channel which operates on a radio frequency distinct from a radio frequency of the second communications channel,
wherein the first wireless node includes a communications interface configured to interface with the first communications channel over which is received the at least one replacement cryptographic key from the remote computing device, and
wherein the at least one operation comprises replacing, as a cryptographic key which secures the secure second communications channel, the current cryptographic key with the at least one replacement cryptographic key.
