“Algebraic Techniques in Differential Cryptanalysis”
That is the title of the talk I am going to give tomorrow at the ISG Research Seminar:
Abstract: We propose a new cryptanalytic method against block ciphers, which combines both algebraic and statistical techniques. More specifically, we show how to use algebraic relations arising from differential characteristics to speed up and improve key-recovery differential attacks against block ciphers in some situations. To illustrate the new technique, we apply it to reduced round versions of the cipher PRESENT, an ultra lightweight block cipher proposed at CHES 2007, particularly suitable for deployment in RFID tags.
Impressions from FSE 2008
If you don’t get it, don’t worry, it is not really funny.
