报告题目:FourQ-basedcryptography for high-performance and low-power applications

要:This work deals with the energy-efficient, high-speed andhigh-security implementation of elliptic curve scalar multiplication, ellipticcurve Diffie-Hellman (ECDH) key exchange and elliptic curve digital signatureson embedded devices using FourQ and incorporating strong countermeasures tothwart a wide variety of side-channel attacks. First, we set new speed recordsfor constant-time curve-based scalar multiplication, DH key exchange anddigital signatures at the 128-bit security level with implementations targeting8, 16 and 32-bit microcontrollers. For example, our software computes a staticECDH shared secret in 6.9 million cycles (or 0.86 seconds @8MHz) on a low-power8-bit AVR microcontroller which, compared to the fastest Curve25519 and genus-2Kummer implementations on the same platform, offers 2x and 1.4x speedups,respectively. Similarly, it computes the same operation in 496 thousand cycleson a 32-bit ARM Cortex-M4 microcontroller, achieving a factor-2.9 speedup whencompared to the fastest Curve25519 implementation targeting the same platform.A similar speed performance is observed in the case of digital signatures.Second, we engineer a set of side-channel countermeasures taking advantage ofFourQ's rich arithmetic and propose a secure implementation that offersprotection against a wide range of sophisticated side-channel attacks,including differential power analysis (DPA). Despite the use of strongcountermeasures, the experimental results show that our FourQ software is stillefficient enough to outperform implementations of Curve25519 that only protectagainst timing attacks. Finally, we perform a differential power analysisevaluation of our software running on an ARM Cortex-M4, and report that noleakage was detected with up to 10 million traces. These results demonstratethe potential of deploying FourQ on low-power applications such as protocolsfor the Internet of Things.
