Seller's Description:
Very Good. Size: 2x6x9; [One of the Best Books on Cryptology, which the US Government attempted to suppress] Hardcover and dust jacket. Good binding and cover. Clean, unmarked pages. Minor shelf wear. Kahn's groundbreaking work in crytology was met with significant resistance from the national security community and NSA. A committee of the United States Intelligence Board concluded that the book was "a possibly valuable support to foreign COMSEC authorities" and recommended "further low-key actions as possible, but short of legal action, to discourage Mr. Kahn or his prospective publishers". Macmillan handed over the Kahn's manuscript to the government for review without Kahn's permission in 1966. Kahn and Macmillan eventually agreed to remove some material from the manuscript, particularly concerning the relationship between the NSA and its counterpart in the United Kingdom, GCHQ.
