  • Analysis of block cipher constructions against biclique and multiset attacks 
    Ghosh, Mohona; Sanadhya, Somitra Kumar (Advisor); Chang, Donghoon (Advisor) (2016-04-18)
    Cryptographic protocols have been a cornerstone of secure communications among armed forces and diplomatic missions since time immemorial. With easy availability and low cost of computing facilities and Internet, the domain ...
  • Authenticated encryption for memory constrained devices 
    Agrawal, Megha; Chang, Donghoon (Advisor); Sanadhya, Somitra Kumar (Advisor) (IIIT-Delhi, 2020-09)
    It is common knowledge that encryption is a useful tool for providing confidentiality. Authentication, however, is often overlooked. Authentication provides data integrity; it helps ensure that any tampering with or ...
  • Design and analysis of approximate matching algorithms 
    Singh, Monika; Chang, Donghoon (Advisor); Sanadhya, Somitra Kumar (Advisor) (IIIT-Delhi, 2022-02)
    With the rapid growth of the World Wide Web and the Internet of Things, huge amounts of digital data are being produced everyday. Digital forensics investigators face an uphill battle when they have to manually screen ...
  • Design and analysis of password-based authentication systems 
    Mishra, Sweta; Chang, Donghoon (Advisor); Sanadhya, Somitra Kumar (Advisor) (IIIT-Delhi, 2017-10)
    Passwords are the most widely deployed means of human-computer authentication since the early 1960s. The use of passwords, which are usually low in entropy, is delicate in cryptography because of the possibility of launching ...
  • Designing generic asymmetric key cryptosystem with message paddings 
    Bansal, Tarun Kumar; Chang, Donghoon (Advisor); Pieprzyk, Josef (Advisor); Sanadhya, Somitra Kumar (Advisor); Boyen, Xavier (Advisor) (IIIT-Delhi, 2017-10)
    RSA-OAEP is being used in PKCS #1 2.0 standard for a long time. OAEP (optimal asymmetric encryption padding) provides security strength to RSA and other deterministic one-way asymmetric primitives (trapdoor one-way ...
  • Digital forensics 2.0: an automated, efficient, and privacy preserving digital forensic investigation framework 
    Verma, Robin; Gupta, Gaurav (Advisor); Chang, Donghoon (Advisor) (IIIT-Delhi, 2018-05)
    The current state of digital forensic investigation is continuously challenged by the rapid technological changes, the increase in the use of digital devices (both the heterogeneity and the count), and the sheer volume of ...
  • Forensics enabled secure mobile computing system for enterprises 
    Govindaraj, Jayaprakash; Gupta, Gaurav (Advisor); Chang, Donghoon (Advisor) (IIIT-Delhi, 2018-05)
    The enterprises are facing constant security threats with the emergence of new mobile computing devices like smartphones, smartwatches, and wearables. The existing digital forensic enabled security solutions are not able ...
  • On the secure design of multi-biometric template protection approaches for biometric authentication 
    Garg, Surabhi; Chang, Donghoon (Advisor) (IIIT-Delhi, 2021-06)
    The biometric systems are widely deployed in various sectors for authentication purposes– India’s Aadhaar project (a multi-biometric database of above 1.3 billion of India’s population) being the prominent example. The ...
