Seems pretty silly putting any form of security apparatus into a technology which could possibly have been engineered from the ground up to be SIGINT-enabled. It's as if GSM was deliberately designed by the intelligence community to be available for eavesdropping. They build the protocol with just enough good security that Johhny can't intercept his wife's calls to check for cheating, but with enough bad security that intelligence services (and sophisticated criminals) can play Mallory[0] [0]: https://en.wikipedia.org/wiki/Alice_and_Bob#Cast_of_characters https://en.wikipedia.org/wiki/Alice_and_Bob#Cast_of_characte...
