Lightweight DES Algorithm (DESL) a été présenté par Axel Poschmann et.al comme un algorithme de cryptage fort, compact et efficace adapté aux ressources de contrainte telles que les WSN, les dispositifs RFID et IOT. Cet article traite de la sécurité du DESL contre la cryptanalyse linéaire qui est une attaque en texte clair connue dans laquelle un grand nombre de paires texte clair-cryptage sont utilisées pour déterminer la valeur des bits clés. La cryptanalyse linéaire fonctionne sur le principe de trouver « des occurrences à forte probabilité d'expressions linéaires impliquant des bits de texte en clair, des bits de texte chiffré et des bits de sous-clé ». De plus, nous montrons que le DESL est plus résistant contre l'attaque de cryptanalyse linéaire que le DES classique.
El algoritmo DES ligero (DESL) fue introducido por Axel Poschmann et.al como un algoritmo de cifrado fuerte, compacto y eficiente adecuado para recursos de restricción como WSN, RFID y dispositivos IOT. Este documento analiza la seguridad del DESL contra el Criptoanálisis Lineal, que es un ataque conocido de texto plano en el que se utiliza un gran número de pares de texto plano-texto cifrado para determinar el valor de los bits de clave. El criptoanálisis lineal funciona según el principio de encontrar "ocurrencias de alta probabilidad de expresiones lineales que involucran bits de texto plano, bits de texto cifrado y bits de subclave". Además, mostramos que el DESL es más resistente contra el ataque de criptoanálisis lineal que el DES clásico.
Lightweight DES Algorithm (DESL) was introduced by Axel Poschmann et.al as a strong, compact and efficient encryption algorithm suitable for constraint resource like WSNs, RFID and IOT devices. This paper discusses the security of the DESL against Linear Cryptanalysis which is a known plaintext attack in which a large number of plaintext-ciphertext pairs are used to determine the value of key bits. Linear cryptanalysis works on the principle of finding "high probability occurrences of linear expressions involving plaintext bits, ciphertext bits, and subkey bits". Furthermore, we show that DESL is more resistant against the linear cryptanalysis attack than classical DES.
تم تقديم خوارزمية DESL خفيفة الوزن (DESL) بواسطة Axel Poschmann et.al كخوارزمية تشفير قوية ومدمجة وفعالة مناسبة لموارد القيود مثل WSNs و RFID وأجهزة إنترنت الأشياء. تناقش هذه الورقة أمان DESL ضد تحليل التشفير الخطي وهو هجوم نصي عادي معروف يستخدم فيه عدد كبير من أزواج النص العادي والنص المشفر لتحديد قيمة البتات الرئيسية. يعمل تحليل التشفير الخطي على مبدأ العثور على "التكرارات عالية الاحتمال للتعبيرات الخطية التي تتضمن وحدات بت النص العادي ووحدات بت النص المشفر ووحدات بت المفتاح الفرعي". علاوة على ذلك، نظهر أن DESL أكثر مقاومة ضد هجوم تحليل التشفير الخطي من DES الكلاسيكي.
