شبكات الاتصال، تشفير البياناتAbstract
يهدف هذا البحث الى جذب الانتباه لضرورة و اهمية تامين البيانات المنقولة عبر شبكات الاتصال والمتداولة بواسطة نظم الحاسبات الالية . والى خطورة النتائج المترتبة على اختراق تلك النظم ..ثم يتعرض لاحد الاساليب الاساسية المتبعة في تامين البيانات وهو اسلوب تشفير البيانات حيث يقدم تعريفا لهذا الاسلوب وطرق تطبيقه باستخدتم خوارزنية تشفير بالاضافة الى مفتاح شفري لتصعيب مهمة مخترقي النظام . ومنها على سبيل المثال استخدام خوارزمية تشفير معقدة وتشفير المفاتيج الثفرية وتغيير قيمتها من حين الى اخر.. الخ واخيرا يناقش البحث الحاجة الى نمطيات موحدة متفق عليها لنظم تشفير البيانات مع ضرب مثال لنظام نمطي ، ثم عرض امثلة لبعض التطبيقات التي تستخدم فيها نظم تشفير البيانات.
