Mode 5 is to upgrade signaling waveforms and allow pilots to interrogate friendly aircraft’s IFF systems at longer ranges using a secure, encrypted code. Rather than changing the code once a day as in Mode 4, Mode 5 relies on modulation techniques to change the code every few seconds to frustrate adversaries.
