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.

A Survey on the provable security using indistinguishability notion on cryptographic encryption schemes Ayar, Emre; Doğanaksoy, Ali; Koçak, Onur; Department of Cryptography (2018) For an encryption scheme, instead of Shannon's perfect security definition, Goldwasser and Micali defined a realistic provable security called semantic security. Using indistinguishability notion, one can define security levels according to the polynomial time adversaries' capabilities such as chosen plaintext attacks (CPA) and chosen ciphertext attacks (CCA) for both symmetric and asymmetric encryption schemes in addition to the hard mathematical problems the algorithms based on. Precautions to prevent the...
Some characterizations of generalized s-plateaued functions Çelik, Emircan; Özbudak, Ferruh; Department of Cryptography (2017) Plateaued functions play important role in cryptography because of their various desirable cryptographic features. Due to this characteristics they have been widely studied in the literature. This studies include p-ary functions and some generalizations of the boolean functions. In this thesis, we present some of this important work and show that plateaued functions can be generalized much more general framework naturally. Characterizations of generalized plateaued functions using Walsh power moments are al...
On Measuring Security Bounds of Some Ciphers Using Mixed Integer Linear Programming (MILP) Approach Türesin, Can; Doğanaksoy, Ali; Koçak, Onur; Department of Cryptography (2021-9-6) Block ciphers are one of the symmetric key encryption algorithms that are used in many devices. Its increasing popularity has led to the emergence of new cryptanalysis methods. Therefore, measuring block cipher's security bounds is one main indispensable need for its designers. Two of the most effective attacks on block ciphers are differential and linear cryptanalysis and these attacks' efficiencies are bonded with a number of active S-boxes of the cipher after a certain number of rounds. Consequently, mea...
A Decision Support System for Optimal Selection of Enterprise Information Security Preventative Actions Özdemir Sönmez, Ferda ; Günel Kılıç, Banu (2021-09-01) Types and complexity of information security related vulnerabilities are growing rapidly and present numerous challenges to the enterprises. One of the key challenges is to identify the optimal set of precautions with limited budget. Despite the fact that majority of enterprises have a budget constraint for installing and maintaining the protection systems, the majority of the previous work only focus on prioritization of security targets and do not consider the preventative actions and budget constraints. ...
Analysis of recent attacks on SSL/TLS protocols Özden, Duygu; Cenk, Murat; Department of Cryptography (2016) Transport Layer Security(TLS) and its predecessor Secure Socket Layer(SSL) are two important cryptographic, certificate based protocols that satisfy secure communication in a network channel. They are widely used in many areas such as online banking systems, online shopping, e-mailing, military systems or governmental systems. Being at the center of secure communication makes SSL and TLS become the target of attackers and an important field of study for researchers. So many vulnerabilities and attacks towar...
