CARiMoL: A Configurable Hardware Accelerator for Ringand Module Lattice-Based Post-Quantum Cryptography (original) (raw)
2021, IACR Cryptol. ePrint Arch.
CARiMoL is a novel run-time Configurable Hardware Accelerator for Ring and Module Lattice-based postquantum cryptography. It’s flexible design can be configured to key-pair generation, encapsulation, and decapsulation for NewHope and CRYSTALS-Kyber schemes using same hardware. CARiMoL offers run-time configurability for multiple security levels of NewHope and CRYSTALS-Kyber schemes, supporting both Chosen-Plaintext Attack (CPA) and ChosenCiphertext Attack (CCA) secure implementations. To the best of our knowledge, it is the first systematically designed full scale hardware accelerator for CCA-complaint multiple LBC schemes that supports run-time reconfigurability without the use of processor such as ARM Cortex series or soft core such as popular RISC-V processors. CARiMol performs logic sequencing on runtime and eliminates the cycle overhead associated with fetch and decode instructions. For the simultaneous use of Ring-LWE and Module-LWE, CARiMoL’s single hardware accelerator has 7...
