Andreas Fackler 15cc6ffddd Separate keys and key shares. 2018-07-18 14:44:35 +02:00

Merge branch 'master' into vk-api-refactor66 2018-07-13 13:53:21 +01:00
Marc Brinkmann 591b546402 Removed unnecessary `Hash` where clause. 2018-07-13 13:27:49 +02:00
Marc Brinkmann 5336fbe707 Added `RandomAdversary` and the necessary auxiliary functions. 
Random adversaries are created for `broadcast` and `honey_badger`.  Random value generation was added for all type-dependencies of these algorithms, causing the `Rand` trait to be implement for a large portion of the codebase.

Additionally, `MessageWithSender` turned into an actual struct, making it much easier to handle. Tuple-like construction is still available through `MessageWithSender::new()`.

Marc Brinkmann 510c4478d4 Ensure the adversary is playing fair and give a more helpful error message if they are not. 2018-07-13 13:27:49 +02:00
Marc Brinkmann a0da8b7385 Added extended example for broadcast api and other docstrings. 2018-07-13 13:27:49 +02:00
Vladimir Komendantskiy 7fb1017bb1 changed Step::output to Vec but that didn't fix the dynamic HB test 2018-07-12 21:23:52 +01:00
Vladimir Komendantskiy 0ba06fdb76 added step output in DistAlgorithm 2018-07-12 14:54:05 +01:00
c0gent f0ed2e6e12 Make `*HoneyBadger` types thread safe. 
Replaces `Rc` with `Arc`. This allows usage from different threads
which will be necessary for use with Parity.

Andreas Fackler c1b4381753 Separate queue from Honey Badger. 
This makes Honey Badger a bit more complicated but a lot more flexible:
It is now unaware of transactions and basically just runs one Subset
instance per epoch.

That way, users can use any kind of external queue, control throttling
and prioritization.

Andreas Fackler 7a0b397233 Add node transaction messages to Dynamic HB. 2018-07-02 14:14:19 +02:00
Andreas Fackler 74fab61dd8 Fix Dynamic HB test. 2018-06-27 11:37:05 +02:00
Andreas Fackler 2a5f9f1bfe Allow observer nodes in all algorithms. 
This allows nodes to join the network without sending any messages
themselves. They can't give any input and just observe the outcome.

Closes #81

Merge pull request #82 from poanetwork/vk-test-decryption-shares 
An adversary sending faulty decryption shares
 2018-06-26 09:06:33 +02:00
Vladimir Komendantskiy 11ec39879b created an adversary to test against faulty decryption shares 2018-06-25 19:22:08 +01:00
Andreas Fackler 062b35ab3a Make SyncKeyGen NodeUid-aware. 
This allows the caller to address nodes by ID instead of by index.

Also contains a few other minor changes that will be needed for
`DynamicHoneyBadger`.
