APPENDIX TWO
‘Y’ Programmes
This is a list of the Diplomatic and Commercial (home stations) supplied to the Canadian National Security E at Ottawa by GCCS in London on 3 June 1942.
It consists of a list of countries whose diplomatic messages were intercepted for the cryptographers in Berkeley Street, together with the relevant call signs and frequencies in kilocycles; which intercept (or ‘Y’) station received the messages or – in the case of Turkey and French Colonial which cable censor – which receiving country received the messages, plus comments when necessary:
APPENDIX THREE
Wartime BJs
Numbers supplied to regular receivers by year (from HW3/162). The DG (Menzies) had copies of all BJs.
APPENDIX FOUR
Venona
Venona was the name given by the Americans to a long lasting series of decryptions of Russian diplomatic messages between the KGB in the form of the Soviet Consul General in New York and Moscow centre. While it was known that references to a Soviet agent nicknamed ‘Gomer’ – or ‘Homer’ – actually referred to Donald Maclean, little else was known about Venona until the NSA released it on the Internet in 1995. Since the second of three tranches released covered the 1943 period and referred (by pseudonyms) to Churchill, Roosevelt, Stalin and the conclusions of several major conferences, it is appropriate to include messages relative to Turkish neutrality in this appendix, and to give a brief account of their emergence.
The Venona material was decrypted by Meredith Gardiner, a US cryptographer. He achieved this by reconstructing the Soviet codebooks. This in turn was achieved because he identified double use of OTP at the Moscow centre end. There are four years’ of material, released in three tranches: the first was the period 1944–52 (released in 1994), the second 1943 and the third 1947–52. The Venona traffic has features in common with BJs: the office’s date and number; the intercepted station, destination and number; a summary of content by way of heading. There are two notable differences. One is the amount of ‘u
nrecovered’ or ‘unrecoverable’ groups in the early stages, so that the meaning or gist of many intercepts is lost. The second is the practice of reissuing decrypts as and when new information justifies it. Some of the 1943 traffic was reissued in 1974, but with key words and names blacked out by the National Security.
