Abstract
The introductions chapters describe specific SPA attack used visual inspection of EM traces, template based attack and collision attack.
After reading the article, the reader is sufficiently informed of any context of SEMA.
Another aim of the article is the practical realization of SEMA which is focused on AES implementation.
The visual inspection of EM trace of AES is performed step by step and the result is the determination of secret key Hamming weight.
On the resulting EM trace, the Hamming weight of the secret key 1 to 8 was clearly visible.
This method allows reduction from the number of possible keys for following brute force attack.
تصف الفصول التمهيدية هجوماً محدداً من هجمات تحليل القدرة البسيط (SPA) باستخدام الفحص البصري للمسارات الكهرومغناطيسية، بالإضافة إلى الهجوم القائم على القوالب وهجوم التصادم.
بعد قراءة المقال، يصبح القارئ على دراية كافية بشتى سياقات التحليل الكهرومغناطيسي البسيط (SEMA).
يتمثل هدف آخر للمقال في التطبيق العملي لـ SEMA مع التركيز على تنفيذ خوارزمية التشفير المتقدم (AES).
يُجرى الفحص البصري للمسار الكهرومغناطيسي لخوارزمية AES خطوة بخطوة، وتتمثل النتيجة في تحديد وزن هامينغ (Hamming weight) للمفتاح السري.
وعلى المسار الكهرومغناطيسي الناتج، كان وزن هامينغ للمفتاح السري من 1 إلى 8 ظاهراً بوضوح.
تتيح هذه الطريقة تقليص عدد المفاتيح المحتملة لتنفيذ هجوم القوة الغاشمة (Brute-force attack) اللاحق.
