Trivial Transciphering With Trivium and TFHE

ePrint Report: Trivial Transciphering With Trivium and TFHE

Thibault Balenbois, Jean-Baptiste Orfila, Nigel P. Smart

We examine the use of Trivium and Kreyvium as transciphering mechanisms for use with the TFHE FHE scheme. Originally these two ciphers were investigated for FHE transciphering only in the context of the BGV/BFV FHE schemes; this is despite Trivium and Kreyvium being particarly suited to TFHE. Recent work by Dobraunig et al. gave some initial experimental results using TFHE. We show that these two …
