Cryptist 2025 | Furkan Akal - Transciphering in FHE

Cryptist is the meeting point of cryptographers across Europe and Asia. For more than three years, it has brought together leading researchers, developers, and builders in Istanbul to discuss the future of #privacy, #cryptography, and #zeroknowledge technologies. In this talk, Furkan Akal explores transciphering in Fully Homomorphic Encryption (FHE) as a practical bridge between lightweight encryption schemes and powerful homomorphic computation, showing how data initially encrypted with efficient symmetric or public-key cryptosystems can be securely transformed into #FHE ciphertexts without requiring native FHE encryption from the start.
