Cryptographic implementations


Page under construction....


We work on various types of cryptographic implementations for both hardware (ASICs and FPGAs) and software targets (from microcontrollers to high-end multicore processors):

(hyper)-ellipitic curve cryptography (ECC)

  • homomorphic encryption (HE)
  • post-quantum cryptography (PQC)
  • arithmetic for cryptography: operators/units, accelerators, librairies
  • protections against physical attacks (observation of side channels, perturbation by fault injection)
  • protections against logical attacks
  • hash functions
  • processor extensions for cryptographic support (symmetric, asymmetric, hash)


Our work on cryptographic implementations also has links to other topics of the ARCAD research group such as computer arithmetic, secure hardware achitectures, reconfigurable architectures, protections against physical attacks
