Paper on accelerating fully homomorphic encryption (TFHE) accepted for CHES 2026

A paper on new integer division and multiplication algorithms for TFHE developed through joint research by AXELL CORPORATION and Kyoto University has been accepted for publication in TCHES, an academic journal associated with the International Conference on Cryptographic Hardware and Embedded Systems (CHES 2026). The paper confirms speedups of up to approximately 3.6 times compared with conventional TFHE-rs.
