deck-based functions

DECK functions can be used for MAC computation, stream encryption, and key derivation. It stands for doubly-extendable cryptographic keyed function. It allows for efficient incremental computing by caching state after computing an output. Xoodoo cookbook

• davies-meyer construction (114)
• sponge functions (114-116)
• authenticated encryption (..)
• strobe, noise and disco (use cases for authenticated encryption and expectations for future systems)
• too much crypto by jp and retroactively reducing required rounds once time has proven robustness (how this reduces required computation and alleviates cost of expensive hash functions)
• fast hashing and kangaroo twelve https://keccak.team/files/KangarooTwelve.pdf
• keccak deck functions and xoodoo (which has fewer rounds)
