In this work, we present a configurable and side channel resistant implementation of the post-quantum key-exchange algorithm CRYSTALS-Kyber . The implemented design can be configured for different performance and area requirements leading to different trade-offs for different applications. A low area implementation can be achieved in 5,269 LUTs and 2,422 FFs, whereas a high performance implementation required 7,151 LUTs and 3,730 FFs. Due to a deeply pipelined architecture, a high operating speed of more than 250 MHz could be achieved on 28nm Xilinx FPGAs. The side channel resistance is implemented using a carefully chosen set of novel and known techniques such as Fault Detection Hashes, Instruction Randomization, FSM Protection and so on. resulting in a low overhead of less than 5% while being highly configurable. To the best of our knowledge, this work presents the first side-channel and fault attack protected configurable accelerator for CRYSTALS-Kyber . Using TVLA (test vector leakage assessment), we validate the implemented protection techniques and demonstrate that the design does not leak information even after 200 K traces. Furthermore, one of the configuration choices results in the smallest hardware implementation of CRYSTALS-Kyber known in the literature.
