SIGSALY (also known as the X System, Project X, Ciphony I, and the Green Hornet) was a secure speech system used in World War II for the highest-level Allied communications. It pioneered a number of digital communications concepts, including the first transmission of speech using pulse-code modulation.

rdfs:comment	SIGSALY (aussi connu sous les noms de X System, Project X, Ciphony I et Green Hornet) est un équipement de codage de la voix développé aux États-Unis par les Laboratoires Bell avec l'assistance du britannique Alan Turing. La première transmission de parole par modulation d'impulsion codée (MIC) a été réalisée avec cet équipement qui était utilisé pour les communications alliées de haut niveau pendant la Seconde Guerre mondiale. Il est pleinement opérationnel début 1944. (fr) SIGSALYとは第二次世界大戦中にアメリカ合衆国のベル研究所で開発された秘話装置で、イギリスのウィンストン・チャーチル首相とフランクリン・ルーズベルト大統領との秘密会談など、アメリカと他の連合国間の重要な通信のために使用された。 SIGSALYの名称はこのシステムを扱ったアメリカ陸軍通信隊（US Army Signal Corps）でのコードネームで特別な意味はない。ベル研究所では X システムやプロジェクト X の名称で呼ばれた。ニックネームはグリーン・ホーネット（Green Hornet）で、通信時の蜂の羽音に似たデジタル変調音が当時有名だったラジオ番組の主題歌に出てくる音に似ていたためそう呼ばれた。 (ja) SIGSALY，也称为X系统、X项目、密码电话 I，或者绿色大黄蜂，它是为二战期间盟军最高层设计的一个经过数字加密的无线电话系统。 SIGSALY是通信系统发展过程中的一个里程碑，当代数字通信耳熟能详的一系列概念在其中首次得以运用，其中包括著名的脉冲编码调制技术（PCM）。 SIGSALY不是首字母缩略词，没有什么含义。别名“绿色大黄蜂”则说出了这个语音通话系统的保密特征——窃听者只能听到像大黄蜂一样嗡嗡作响的噪声。 (zh) SIGSALY (also known as the X System, Project X, Ciphony I, and the Green Hornet) was a secure speech system used in World War II for the highest-level Allied communications.

(en) In crittografia, SIGSALY (noto anche come X System, Project X, Ciphony I, e Green Hornet) era un sistema vocale sicuro utilizzato nella seconda guerra mondiale per le comunicazioni alleate di livello più alto. Ha aperto la strada una serie di concetti di comunicazione digitale, tra cui la prima trasmissione audio in modulazione a impulsi codificati. (it) Na criptografia, SIGSALY (também conhecido como o Sistema X, Projeto X, Ciphony I, e Green Hornet) foi um sistema de transmissão segura da voz usado na II Guerra Mundial para as comunicações de alto nível entre os Aliados. (pt) SIGSALY (также известная как X System, Project X, Ciphony I и Green Hornet) — защищенная речевая система, использовавшаяся во время Второй мировой войны для коммуникаций самого высокого уровня. SIGSALY стала одной из первых систем, использовавших ряд концепций цифровых коммуникаций, включая первую передачу речи с использованием импульсно-кодовой модуляции. (ru)
