BID/610, codenamed Alvis, was a British cipher machine[1] used by both British and Canadian governments[2][3] and also by NATO. It was the first fully transistorised full-duplex online cipher machine used by the British Army.[3] It was introduced in the 1960s [3] and was approved for NATO-wide use on 17 April 1962,[4] after winning a NATO-evaluation for a Tapeless Rotorless On-Line (TROL) cipher machine.
