    • Automatic characterization of exploitable faults : a machine learning approach 

      Saha, Sayandeep; Jap, Dirmanto; Patranabis, Sikhar; Mukhopadhyay, Debdeep; Bhasin, Shivam; Dasgupta, Pallab (2019)
      Characterizing the fault space of a cipher to filter out a set of faults potentially exploitable for fault attacks (FA), is a problem with immense practical value. A quantitative knowledge of the exploitable fault space ...
    • DFARPA: Differential Fault Attack Resistant Physical Design Automation 

      Khairallah, Mustafa; Sadhukhan, Rajat; Samanta, Radhamanjari; Breier, Jakub; Bhasin, Shivam; Chakraborty, Rajat Subhra; Chattopadhyay, Anupam; Mukhopadhyay, Debdeep (2018)
      Differential Fault Analysis (DFA), aided by sophisticated mathematical analysis techniques for ciphers and precise fault injection methodologies, has become a potent threat to cryptographic implementations. In this paper, ...
    • A Practical Fault Attack on ARX-Like Ciphers with a Case Study on ChaCha20 

      Kumar, S. V. Dilip; Patranabis, Sikhar; Breier, Jakub; Mukhopadhyay, Debdeep; Bhasin, Shivam; Chattopadhyay, Anupam; Baksi, Anubhab (2017)
      This paper presents the first practical fault attack on the ChaCha family of addition-rotation-XOR (ARX)-based stream ciphers. ChaCha has recently been deployed for speeding up and strengthening HTTPS connections for Google ...
