• EncryptedKeyFrag
  Encrypted and signed key frag.
• EncryptedThresholdDecryptionRequest
  An encrypted request for an Ursula to derive a decryption share.
• EncryptedThresholdDecryptionResponse
  An encrypted response from Ursula with a derived decryption share.
• EncryptedTreasureMap
  A treasure map encrypted for Bob.
• FleetStateChecksum

  A request for an Ursula to derive a decryption share.
• ThresholdDecryptionResponse
  A response from Ursula with a derived decryption share.
• TreasureMap
  A structure containing KeyFrag objects encrypted for Ursulas chosen for this policy.
• VerificationError
