SUMMARY:Scaling of Memory and Bandwidth Requirements of Post-Quantum Signat
 ures with Message Size
DESCRIPTION:In this work we analyse the qualitative memory and bandwidth ef
 ficiency properties of the currently standardised post-quantum signatures a
 s such\, and of their protocol integrations mainly in the X.509 context. Th
 e term qualitative in this respect refers to how memory and bandwidth requi
 rements scale with the size of the signed message.\n\nSpecifically\, we add
 ress the question of how far the algorithms support online computations\, a
 lso known as streaming\, with respect to the signed message in the signing 
 and verification operations. Further\, we review the possibilities for the 
 pre-computation of a short message representative outside the cryptographic
  module responsible for the signing or verification operation of the differ
 ent signature schemes. We also give a preview of the corresponding cryptogr
 aphic API of the PKCS#11 standard\, which introduces numerous PQC signature
  algorithms in the upcoming version 3.2.\n\nWe demonstrate that for specifi
 c realistic use cases\, the qualitative memory and bandwidth efficiency of 
 the PQC signature schemes in protocol use varies widely and tends to be sub
 stantially degraded compared to the traditional signature schemes based on 
 RSA and elliptic curves\, which always allow for the pre-computation of a s
 hort message representative in the form of a hash value. Our results are re
 levant to PQC migrations of existing applications using traditional RSA or 
 elliptic curve schemes.\n\n\nSpeakers: Falko Strenzke
