Behind the Enigma: The Authorised History of GCHQ, Britain’s Secret Cyber-Intelligence Agency

Good condition, got what I paid for

Vient couronner une longue série d'ouvrages sur le sujet (Enigma, GCHQ, renseignement et cryptopgraphie) Mais ne se limite plus à la seule Seconde guerre mondiale et couvre une période beaucoup plus récente, après être remonté aux origines, dès le début du XXe siècle ! Ouvrage majeur sur le sujet...

Although this is a comprehensive history of GCHQ, it is also an easy read. Plenty of photographs too. GCHQ is often the more overlooked member of the three security services with Mi5 the Security service and Mi6 Secrey Intelligence Service. Yet GCHQ is perhaps the one that has the main influence for the general public. In addition to its intelligence gathering it also fights cyber attacks and protect our increasingly cyber dominated life. I thought I was already informed about the work of GCHQ and its NCSC (National Cyber Security Centre), but learnt a great deal from reading this book, realising my existing knowledge was rather limited.

A true must read for those that follow the crypto world. Well researched. Well written. Furst person accounts. Impeccable interpretations.
