A multi-party remote bitstream update protocol using key chains

摘要

Remote update of reconfigurable hardwares is an essential service which enable by Field Programmable Gate Arrays (FPGA) through a network. During the remote updating of the configurations of the FPGA cluster, the efficiency of the current two-party bitstream update protocol is low. So these protocols cannot meet the requirement of the FPGA cluster update. In this paper, we propose a multi-party remote bitstream update protocol with forward-secure that ensures bitstream confidentiality and integrity and prevents replay attacks.
