DESCRIPTION:Title: Hardware Implementation of a Stealthy and Lightweight Ba
 ckdoor for CRYSTALS-Kyber in Hybrid Cryptosystems\n\nSpeaker: Dr. Debapriy
 a Basu Roy\, Assistant Professor\n\nDepartment of Computer Science and Eng
 ineering\nIndian Institute of Technology Kanpur\n\nDate and time: Monday\,
  July 27\, 2026\, 2:45-3:45 PM\nLocation: George Mason University\, Engine
 ering Building room: ENGR 3507\n\nAbstract: The threat of practical quantu
 m attacks has catapulted viable alternatives\, like Post-Quantum Cryptogra
 phy (PQC)\, into prominence. The adoption and integration of standardized 
 PQC primitives across the entire digital stack are promoted by various sta
 ndardization bodies\, governments\, and major corporate houses. A serious 
 challenge in quantum migration is ensuring that there is no hidden backdoo
 r in the PQC implementations of a hybrid cryptosystem (supporting both pre
 -quantum and post-quantum algorithms)\, which are often procured from a th
 ird-party vendor. In this presentation\, we investigate the possibility of
  a Kleptographic backdoor on the\n\nNIST-recommended key-encapsulation mec
 hanism CRYSTALS-Kyber. The modified Kyber Key-Generation algorithm achieve
 s an indistinguishable decryption failure probability that is indistinguis
 hable from that of the original CRYSTALS-Kyber. The Kleptographic module i
 s also implemented in an FPGA and embedded in the CRYSTALS-Kyber accelerat
 or\, with a very low area overhead (283 LUTs or 2% of total area). It can 
 thus easily pass performance and functionality tests.\n\nRoom: 3507\, Bldg
