External Cryptanalysis Categories

From The ECRYPT Hash Function Website

For presentation reasons, we provide a simplified overview about cryptanalytic results in The SHA-3 Zoo. We only consider cryptanalytic results that have not been performed by the designers themselves and are included in the initial proposal, hence the name 'external'. Exceptions are cryptanalytic results by non-designers and cryptanalytic results by designers that are not mentioned in the proposal.

We use the following categories for External Cryptanalysis:

  • none: no external cryptanalysis is known
  • yes: there are cryptanalytic results known
  • broken: external cryptanalytic results disprove claims by the designers and/or requirements for a future SHA-3
