Speeding Up OMD Instantiations in Hardware
Abstract
Particular instantiations of the Offset Merkle Damgaard authenticated encryption scheme (OMD) represent highly secure alternatives for AES-GCM. It is already a fact that OMD can be efficiently implemented in software. Given this, in our paper we focus on speeding-up OMD in hardware, more precisely on FPGA platforms. Thus, we propose a new OMD instantiation based on the compression function of BLAKE2b. Moreover, to the best of our knowledge, we present the first FPGA implementation results for the SHA-512 instantiation of OMD as well as the first architecture of an online authenticated encryption system based on OMD.
