Mutual Information Analysis : A Universal Differential Side-Channel Attack
Benedikt Gierlichs, Lejla Batina, Pim Tuyls · 2007
1 Introduction Currently, embedded devices form the major part of the CPU market [16]. It seems that the vision of Pervasive Computing or Ambient Intelligence is being realised since we are more and more surrounded by devices such as smart cards, mobile phones, PDAs and more recently RFIDs and sensor nodes. These devices typically operate in hostile environments under control of a potential attacker and hence the data contained in them might be relatively easy compromised. Due to the tight constraints on their resources such as memory, number of gates, power etc., it is a very challenging task to protect the information they carry in an adequate way.
