Spycatcher - Subsequent Impact

Subsequent Impact

The concepts and use of Public Key Infrastructure were discovered by James H. Ellis and British GCHQ scientists in 1969. After the re-discovery and commercial use of PKI by Rivest, Shamir, Diffie and others, the British government considered releasing the records of GCHQ's successes in this field. However, the untimely publication of Spycatcher meant that the government once again issued a gag order and full details of GCHQ achievement were never revealed. Richard Walton from GCHQ later said "It was a time when the government security market was expanding beyond the traditional military and diplomatic customer, and we needed to capture the confidence of those who did not traditionally deal with us. We were in the middle of Thatcherism, and we were trying to counter a sort of 'government is bad, private is good' ethos. So, we had the intention of publishing a paper, but that idea was scuppered by that blighter Peter Wright, who wrote Spycatcher."

Famous quotes containing the words subsequent and/or impact:

    Children of the same family, the same blood, with the same first associations and habits, have some means of enjoyment in their power, which no subsequent connections can supply; and it must be by a long and unnatural estrangement, by a divorce which no subsequent connection can justify, if such precious remains of the earliest attachments are ever entirely outlived.
    Jane Austen (1775–1817)

    Television does not dominate or insist, as movies do. It is not sensational, but taken for granted. Insistence would destroy it, for its message is so dire that it relies on being the background drone that counters silence. For most of us, it is something turned on and off as we would the light. It is a service, not a luxury or a thing of choice.
    David Thomson, U.S. film historian. America in the Dark: The Impact of Hollywood Films on American Culture, ch. 8, William Morrow (1977)
