Post-quantum key encapsulation

NewHope

NewHope is a key-exchange protocol based on the Ring-Learning-with-Errors (Ring-LWE) problem, which was submitted to the NIST post-quantum crypto project. The submission proposes four different instantiations:

  • NewHope512-CPA-KEM and NewHope1024-CPA-KEM, which are IND-CPA-secure key encapsulation mechanisms which target level 1 and level 5, respectively, in the NIST call for proposals (matching or exceeding the brute-force security of AES-128 and AES-256, respectively)
  • NewHope512-CCA-KEM and NewHope1024-CCA-KEM, which are IND-CCA-secure key encapsulation mechanisms which target level 1 and level 5, respectively, in the NIST call for proposals (matching or exceeding the brute-force security of AES-128 and AES-256, respectively)
