"Without ever becoming quite that wild-eyed, Levy's reporting verges on advocacy journalism--particularly in his accounts of the long-term conflict between the rebel cryptographers and authorities at the N.S.A. The libertarian ethos of the cryptography underground treats the right to privacy as an absolute. To them, the idea that the public good could be threatened by the power of anyone to conceal anything is hopelessly irrelevant. Those who raise such concerns are, it seems, just making themselves hysterical by imagining drug-dealing pedophiles with black-market atomic bombs. All efforts by the government to control the development and dissemination of encryption are shown as misguided and pointless, if not in fact Big Brotherly.Levy, Steven is the author of 'Crypto How the Code Rebels Beat the Government-- Saving Privacy in the Digital Age', published 2002 under ISBN 9780140244328 and ISBN 0140244328.
