Merge branch 'master' into vk-api-refactor66 2018-07-13 13:53:21 +01:00
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()`.

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
Andreas Fackler 3f3ac7be13 Minor fixes and simplifications. 
* Clear outdated key gen messages from the buffer.
* Process output after proposing, to make `HoneyBadger` work with a
  single validator.
* Print an error if threshold decryption fails.
* Verify decryption shares with the correct ciphertext.
* Insert all ciphertexts from an epoch at once; otherwise contributions
  can be omitted from a batch.
* Remove `BoolWithFaultLog`: It's easier to return a tuple, and it's
  used only in one place now.
* Avoid redundant signature verification in `VoteCounter`.
* Fix the tests for `QueueingHoneyBadger`.
* Use fewer network sizes to speed up tests a bit.

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.

Peter van Nostrand 6783ece9b0 Added faulty node logging to algorithms. 2018-07-09 13:45:11 -04:00
Andreas Fackler 93ca149757 Apply rustfmt and expand HB doc comment. 2018-07-05 11:47:19 +02:00
c0gent 2408e012fe Add type to `HoneyBadgerBuilder`. 2018-07-05 11:47:19 +02:00
Andreas Fackler 1a3016d94d Add Honey Badger builder. 2018-07-05 11:47:19 +02:00
Andreas Fackler 0f92010fe4 Add a max_future_epochs option to Honey Badger. 
This delays handling of messages from epochs that are too far ahead.
 2018-07-05 11:47:19 +02:00
Andreas Fackler 515bd14a23 Restart Honey Badger when DKG starts for joining validator. 
That way the user can be sure that if they forward all `Target::All`
messages after the first batch mentioning a joining validator, they
don't miss any messages relevant for that joining node.

Andreas Fackler aaec3d4074 Simplify observer/peer-specific code. 
Extract some methods to make the branches more readable.
 2018-06-26 14:50:06 +02:00
Andreas Fackler 2db67df325 Rename is_full_node to is_peer. 2018-06-26 10:57:44 +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`.

Vladimir Komendantskiy c7f4994e3a threshold encryption of proposals in HoneyBadger 2018-06-22 10:12:38 +01:00
Andreas Fackler 83f8d61402 Support serde by default. 
This removes the `serialization-serde` feature, since serde is already
used internally and therefore a dependency anyway.
 2018-06-20 10:21:52 +02:00
Andreas Fackler 66f396e01c Remove more NodeUid trait bounds. 
Use a `BTreeMap` instead of `HashMap` in `NetworkInfo`. The number of
nodes can't grow very large anyway.
 2018-06-18 16:37:07 +02:00
Andreas Fackler 3f707a8e12 Return proposer info from HoneyBadger. 
Also, consistently name generic arguments, and remove some unused trait
bounds.
