Hosted by ISI Kolkata, the 2026 edition brings together India's cryptographic research community for collaborative research across all sub-areas of cryptology. November 30 – December 4, 2026.
Crypto Winter School was introduced last year with the objective of fostering cryptographic research within the Indian cryptography community. The school follows a Dagstuhl Seminar-style format, featuring invited talks by eminent cryptographers from the Indian community alongside focused group discussions and collaborative research sessions. The aim is to encourage interaction, exchange of ideas, and the development of new research collaborations among cryptographers from different parts of India.
ISI Kolkata's Local Organizing Committee is finalizing the syllabus and thematic focus for 2026. Full programme details will be published here as they're confirmed. TBA
Tentative — subject to change as the programme is finalized.
