A Study on countermeasures on AES against side channel attacks

Çenesiz, Damla
Side Channel Attacks have a important role for security of cryptographic algorithm. There are different method which include Threshold Implementation to protect against these kind of attacks. In this thesis, we study certain countermeasures to side channel attacks for AES. We start with a survey on Side Channel Attacks for block ciphers and we mentioned attack models for AES.We give also partical attention Treshold Implementation properties and construction methods. We also give some details of subfield construction and Threshold Implementation of AES.
