BID 610
Date invented	1960s


Type	cipher machine

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.
