Denial and deception (D&D) is a Western theoretical framework〔 for conceiving and analyzing intelligence techniques pertaining to secrecy and deception. Originating in the 1980s, it is roughly based on the more pragmatic Soviet practices of maskirovka (which preceded the D&D conceptualization by decades) but it has a more theoretical approach compared to the latter.〔Hutchinson, William. (2004) "The Influence of Maskirovka on Contemporary Western Deception Theory and Practice." Proceedings of the 3rd European Conference on Information Warfare and Security. ISBN 0-9547096-2-4.〕 In the D&D framework, denial and deception are seen as distinct but complementary endeavors.〔 Denial most often involves security and concealment to prevent foreign agents, photographic surveillance, electronic monitoring, or even the media from revealing secretive diplomatic or military matters. Deception is the construction of a false reality for the adversary through intentionally "leaked" false information, false stories implanted in the media, dummy or decoy structures or military formations, or numerous other measure.〔 For example, in the Japanese information warfare campaign that preceded the Japanese attack on Pearl Harbor, the D&D approach identifies as a denial measure the twice-repeated change in naval call signs effected by the Imperial Navy between 1 November and 1 December, but identifies as a deception measure the Japanese Foreign Office announcement that a large Japanese liner would sail to California on December 2 to evacuate Japanese citizens. A denial and deception campaign is most effective when numerous denial and deceptive efforts are coherently coordinated to advance a specific plan; however, the most effective such operations are very complex, involving numerous persons or organizations, and this can prove exceedingly difficult. A single failed denial measure or deception can easily jeopardize an entire operation.〔Abram Shulsky, "Elements of Strategic Denial and Deception," in ''Strategic Denial and Deception: The Twenty-First Century Challenge'', ed. Roy Godson and James J. Wirtz (Piscataway: Transaction Publishers, 2002), 15-17; Roy Godson and James J. Wirtz, "Strategic Denial and Deception," ''International Journal of Intelligence and Counterintelligence'' 13 (2000): 425-426.〕 According to Abram Shulsky, democracies, like the United States, had difficulty employing denial and deception campaigns. This is largely due to the open media of most such societies which frequently expose any major operations undertaken militarily or diplomatically. Also, legal restrictions tend to hamper governments and particularly intelligence services in democratic societies. The exception to these restrictions occurs in wartime, when some measure of martial law is imposed and legal impediments are relaxed. Authoritarian systems of government, however, frequently employ denial and deception campaigns both domestically and abroad to manipulate domestic opposition and foreign governments. These operations are unhampered by legal restrictions or an open media. Non-state actors, such as terrorist organizations, frequently use denial and deception to influence governments and the public opinion of target societies.〔''Ibid''., 427-428.〕 Other authors illustrate the D&D topic with Operation Fortitude and consider it one of the most successful such examples in history.〔 Article previously published in ''Air Power History'', vol. 37, no. 3, Fall 1990, pp. 15-22〕 According to Donald C.F. Daniel democratic societies have more qualms with deception than they have with denial (in the technical sense used in this article); Daniel contrasts the little public controversy that surrounded the secretive way in which Nixon's rapprochement with China was negotiated (as example of secrecy/denial that did not cause a public outrage) with the uproar caused by the announcement of 2001 announcement of the Office of Strategic Influence (an institution that had among its stated goals the planting of false stories in the foreign press).〔 According to United States Department of Defense definitions, military deception includes both denial and deception (as defined in the D&D framework).〔Johnson, Mark, and Jessica Meyeraan. "(Military deception: Hiding the real-showing the fake )". Joint Forces Staff College, Joint and Combined Warfighting School, p. 4〕 Canadian OPSEC officer John M. Roach notes that "Deception used as a broad, general term includes the elements of both denial and deception, each having distinct actions that are either active or passive."〔 D&D is not the only terminology used to make this distinction; according to Roach "passive deception" is another technical term for denial.〔John M. Roach, (DECEPTION: Can information superiority be achieved with or without it? ), Newsletter of the OPSEC Professionals Society, July 2012, Volume 3, Issue 2, p. 7. Also published in (The Canadian Army Journal Vol. 10.3 Fall 2007 ), p. 117-120〕 Western writers see the Soviet (and post-Soviet) maskirovka practices as not drawing a sharp or significant distinction between the two components of denial and deception.〔〔 The Islamic concepts of kitman and taqiyya, or at least the jihadist interpretations thereof, have been seen by Westerners as the equivalents of the two components of denial and (respectively) deception.〔 Since taqiyya is a word with Shiite connotations, Sunni militants sometimes prefer to use the word iham instead, roughly with the meaning "deception of unbelievers". Although the Chinese deception theory literature is vast and uses rather different terminology (relative to Western works), some recent surveys have identified that "seduction"— understood as convincing the enemy to make fatal mistakes—is considered the highest form of deception while confusing or denying information to the enemy are considered lesser forms. ==See also== *Disinformation *False flag 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Denial and deception」の詳細全文を読む スポンサード リンク
