http://dbpedia.org/ontology/abstract A permissive action link (PAL) is an accesA permissive action link (PAL) is an access control security device for nuclear weapons. Its purpose is to prevent unauthorized arming or detonation of a nuclear weapon.The United States Department of Defense definition is: A device included in or attached to a nuclear weapon system to preclude arming and/or launching until the insertion of a prescribed discrete code or combination. It may include equipment and cabling external to the weapon or weapon system to activate components within the weapon or weapon system. The earliest PALs were little more than locks introduced into the control and firing systems of a nuclear weapon, that would inhibit either the detonation, or the removal of safety features of the weapon. More recent innovations have included encrypted firing parameters, which must be decrypted to properly detonate the warhead, plus anti-tamper systems which intentionally mis-detonate the weapon, destroying it without giving rise to a nuclear explosion.ithout giving rise to a nuclear explosion. , Un Permissive Action Link (PAL) è un dispoUn Permissive Action Link (PAL) è un dispositivo di sicurezza di controllo accessi per armi nucleari. Ha la funzione di escludere che un'arma nucleare venga armata o fatta detonare in modo non autorizzato.La definizione dello United States Department of Defense è: I primi PAL erano poco più che lucchetti introdotti nei sistemi di controllo e sparo di un'arma nucleare, che avrebbero dovuto inibire la detonazione, o la rimozione delle caratteristiche di sicurezza dell'arma. Le innovazioni più recenti annoverano parametri di sparo criptati, che devono essere decriptati per fare esplodere correttamente la testata, oltre a sistemi anti-manomissione che intenzionalmente fanno detonare in modo errato l'arma, distruggendola senza dar luogo ad un'esplosione nucleare.senza dar luogo ad un'esplosione nucleare. , Permissive Action Link (PAL) ist die BezeiPermissive Action Link (PAL) ist die Bezeichnung einer US-amerikanischen Sicherheitsvorrichtung für Atomwaffen, die deren ungewollte Detonation bei Unfällen oder Missbrauch verhindern soll. Dabei schützt ein geheimer PAL-Code, der die Waffe scharfschalten kann, vor einer Zündung durch Flugzeugabstürze, Blitzeinschläge, Feuer, Explosionen oder durch unautorisierte Personen wie etwa Dissidenten innerhalb der Streitkräfte oder Terroristen. Ebenso verhindert das System die Überbrückung von Schaltkreisen und andere Manipulationen an der Atomwaffe. Das Verteidigungsministerium der Vereinigten Staaten definiert PALs wie folgt: „Eine integrierte oder extern angebrachte Vorrichtung an einem nuklearen Waffensystem, die das Scharfschalten und/oder Abfeuern dessen verhindert, bis die Eingabe eines vorher festgelegten Einzelcodes oder einer Code-Kombination erfolgt. Unter Umständen beinhaltet sie Anlagen und Verkabelungen, die sich außerhalb der Waffe oder des Waffensystems befinden, um Komponenten innerhalb der Waffe oder des Waffensystems zu aktivieren.“ Technische Details der PAL-Systeme unterliegen der Geheimhaltung. Durch Weiterentwicklungen und den allgemeinen technischen Fortschritt in den letzten Jahrzehnten gibt es inzwischen verschiedene Ansätze und Umsetzungen in der Konstruktion. Alle Systeme basieren jedoch auf dem Grundsatz, dass die Waffe ohne die Eingabe eines Codes nicht zur Detonation gebracht werden kann.nicht zur Detonation gebracht werden kann. , Un dispositif de sécurité et d'armement, oUn dispositif de sécurité et d'armement, ou système de verrouillage électronique, est un système de sûreté permettant de verrouiller et de sécuriser l'emploi de certaines armes, notamment les armes nucléaires. Appelé Permissive Action Link par les Américains, son activation est typiquement conditionnée par l'emploi d'un ou d'une série de codes d’autorisation par une personne spécifique. Dans le cas des armes nucléaires, il s'agit du chef de l'État ou de l'autorité militaire le cas échéant. Le dispositif a été surnommé « le bouton rouge » (Big red button ou The Button, en anglais).Big red button ou The Button, en anglais).
