SUMMARY:Security in the Presence of Quantum Adversaries: Extraction and Tam
 per Resilience
DESCRIPTION:Speaker: B. Naresh Goud (National University of Singapore)\n\nA
 bstract: \nQuantum information is reshaping our understanding of both comp
 utation and security. Quantum algorithms challenge widely used cryptograph
 ic assumptions\, while quantum systems introduce new adversarial capabilit
 ies based on entanglement and measurement. This shift raises foundational 
 questions in cryptography: how do classical notions of security and inform
 ation evolve in the presence of quantum adversaries?In this talk\, I will 
 present a research program focused on developing cryptographic primitives 
 that remain secure against quantum side information and quantum tampering.
  I will describe constructions of quantum-secure non-malleable extractors 
 and non-malleable codes\, and show how quantum information enables tamper-
 detecting codes in the split-state model\, a task provably impossible in t
 he classical setting. These results demonstrate that entanglement can func
 tion not only as an attack resource\, but also as a defensive tool that en
 ables fundamentally new forms of protection.Together\, these results contr
 ibute to a unified theory of security and information in the presence of q
 uantum adversaries\, bridging quantum information theory and modern crypto
 graphy.Brief Bio: Naresh Goud Boddu is a researcher in quantum information
  and quantum cryptography. He is currently a Senior Research Fellow in the
  Department of Computer Science\, NUS\, Singapore. He most recently served
  as Vice President and Applied Research Lead at JPMorgan Chase in Singapor
 e\, where he led work on post-quantum cryptographic applications for indus
 try. Previously\, he was a Postdoctoral Fellow at NTT Research in Californ
 ia in the Cryptography and Information Security Laboratories\, mentored by
  Prof. Vipul Goyal and Prof. Dakshita Khurana.\n
