Overview

Enigma Core library

Service	Master	Develop
CI Badge

Pure Rust Enclave && Untrusted in Rust. Core is part of the Enigma node software stack. The Core component as it's name suggests is responsible for the core operations. The core includes Remote Attestation (SGX SDK), Cryptography and execution of WASM secret contracts.

Getting Started (With the Enigma Docker)

Prerequisites

RUST-SGX-Intel SGX SDK 2.1.3 for Linux installed.
clone this repo into /some/path/enigma-core.
Docker - Install.

Build and Compile

build the enigma docker image

 cd /some/path/enigma-core/dockerfile
 docker build -t enigma_core .

The output should look like that:

run docker:

docker run -v /some/path/enigma-core/:/root/enigma-core -ti -p 5552:5552 --device /dev/isgx enigma_core

build the project

cd enigma-core/enigma-core
make

If the following error occurs then this is an open issue that will be solved.

error: aborting due to previous error

For more information about this error, try `rustc --explain E0463`.
error: Could not compile `sgx_tunittest`.

check out Troubleshooting and then make clean && make

Run the tests (inside Docker)

Build the project

make
cd app/

Run the tests (no std)

cargo test

Run the test (with std)

cargo test -- --nocapture

Run the project

cd root/enigma-core/enigma-core/bin
./app

Simulation Mode

If you want to run this in a computer that doesn't support SGX you can run both enigma-core and surface in simulation mode.
To do this, run surface with --simulation, then fire up the docker and run:

$ cd enigma-core
$ make full-clean
$ export SGX_MODE=SW
$ make # Here you can add JOBS=N to pass on to cargo the number of jobs to run simultaneously.

Comments

Principal with Key Management
Notes:

Deploying the Enigma contract does not work. You'll notice that related sections of the code are commented out. I did not completely remove them because we may want to re-enable them or adapt to your integration test framework. There are two reasons why I chose to disable this:

Rust Web3 does not support deploying contracts with linked libraries: https://github.com/tomusdrw/rust-web3/issues/186. We could submit a PR to enable it but I determined that it was not a priority.

New business logic like the worker selection algorithm requires extensive setup (registering multiple workers, crossing epoch, etc).

Here is what I did to compensate:

Added lower level unit tests with mock data that does not interface with the live contract.

Made the CLI commands more granular (which useful beyond testing) and added a mode to Enigma.specs.js that invokes the live Principal node. This way, we can substitute the mock for live Principal node and without changing the tests. This was the most convenient way for me to test and also a good bridge to the full integration test script.

Added a confirmations parameter to the enigma_contract module in addition to supporting the new methods in the contract.

I'm using a specific terminology for some of the for the epoch and keys modules. I'm also using the _u and _t but there was still overlap: 1) Provider: Provide external data; 2) Keeper: Store and verify data in the enclave. I'm happy to refactor this if you suggest a different convention.

The keys_keeper_types module is copied across: app/src/esgx/keys_keeper_u.rs and enclave/src/keys_keeper_t/keeper_types_t.rs. I tried to make a reusable module that works both in the enclave and out ran into issues and aborted for now.

I created enigma-tools-t/src/document_storage_t.rs which is based upon storage_t.rs but supports variable byte array size. It also has improved error handling. I believe that it can replace storage_t.rs.

TODOs:

Seal the epoch data. I have a plan for this to did not have time to finish. Instead of sealing the entire epoch data, I want to seal the nonce + a hash. The epoch_provider will fetch the epoch data and call set_worker_params and pass the nonce. Instead of incrementing the nonce, the epoch_keeper will verify the data against the hash and store in memory.

I could not get the Makefile to copy enigma-types.h in the enclave folder. I included a temporary workaround on line 111 of enigma-principal/Makefile. I would appreciate if you could take a look. This causes the build to fail on the CI server.

Worker selection is disabled for the time being (it always return the keys). I'm working on testing more thoroughly and will push an update shortly.

I cherry picked commit 346a8e40827ee4f9af0f56186d72ac916f26cf6f because I needed a working SPID. Now the attestation_service::service::test tests are failing. The root cause is not obvious to me. I will wait until the related PR is finalized to troubleshoot.

Logging is not implemented in the enclave.

FIX: Fixed an issue with the `test_write_epoch_state` unit test.

This test runs before warming up the storage dirs. The fix is temporary. I'm currently working on improving the unit test organization. I will submit a PR that fixes this permanently and handles setup more gracefully. In the meantime, this will fix the test. I did not detect this locally because the test setup did not delete the local storage, which I will remediate in the next PR. I do not know why the CI behaved differently on this branch and develop.

Principal Node Error: Error("missing field `platformInfoBlob`"...

Describe the bug I'm consistently getting this Error("missing field platformInfoBlob"... when running the principal node. Also, debug messages are being weirdly duplicated. This error occurs with any command. I did some troubleshooting but wasn't able to isolate the root cause. Before creating this issue, I completely re-initialized my environment (see issue #9). The enigma-core unit tests are passing. I can run the SGX Rust SDK sample app so my SGX driver seems to work. My ganache-cli is running and I can see transactions being mined successfully.

Possible typo in array initialization in erc20 secret contract example
Describe the bug Referencing dev-help issue: https://github.com/enigmampc/dev-help/issues/9

User encountered a decryption error during enclave execution which was narrowed down to the line:

let mut new_sig: [u8; 65] = [0u8; 65];

that he copied from the verify() method here: enigma-core/examples/eng_wasm_contracts/erc20/src/lib.rs

It looks like a typo with the 0u8 instead of 0, but I'm not sure. I can't find any examples of initializing an array in Rust that way, but rustc doesn't complain about it.

To Reproduce Steps to reproduce the behavior:

Use erc20 example SC as a base to create a test SC

Include the verify() function

Compile, migrate and deploy

Write a test to call the verify function

See error

Expected behavior No decryption error

Select Epoch By BlockNumber
This PR modifies the epoch state management to store N epoch and make them available for worker selection verification.

Here are some key requirements (also documented in EP-648):

The number of epoch stored should be configurable

The epoch state will be stored in the untrusted module and verified in the enclave. This extends the current sealed EpochState hash model and has been mostly implemented in issue EP-646 .

The JSON-RPC endpoint will contain a new optional blockNumber parameter corresponding to the block number of a Task Record. The Key Mgmt node will select the corresponding epoch if available. If not specified, the last confirmed epoch will be used.

FIX: Fixed an issue with using Hash256 in the epoch state and added a…

It seems like Serde does not automatically serialize Struct HashMap keys so I implemented a custom serializer. I also added a unit test to catch this sort of issue in the future. This was caught be Enigma.spec.js but unit tests did not have sufficient coverage.

This should resolve issue #110.

[Ppal Node]: Retries for connecting to sgx.enigma.co

Is your feature request related to a problem? Please describe. I got the following error while launching the Principal Node:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Error { kind: Io(Custom { kind: TimedOut, error: StringError("timed out") }), url: Some("https://sgx.enigma.co/api") }

I don't know if this would also be an issue in Core? Cc: @elichai

https://sgx.enigma.co/api was indeed online at the time, and a subsequent manual request succeeded.

Describe the solution you'd like I would suggest coding in at least 3 retries for trying this connection, otherwise the Principal Node crashes.

Describe alternatives you've considered N/A

A redeployment of an existing contract fails with Missing State Key

Describe the bug A second attempt to redeploy a contract, regardless of whether the first one succeeded or failed (as in #113), errors out with Cryptography Error: MissingKeyError { key_type: "State Key" }. This seems to have nothing to do with core 's ability to request the right state keys from the Key Management node, as this behavior can be observed when the 1st and 2nd deployment happen in the same epoch, when the state keys should be arguably the same.

To Reproduce

Deploy one valid secret contract, that succeeds.
Attempt to redeploy the very same contract.

Expected behavior If a contract exists at a given address, it should error out with a relevant message.

This opens the question on whether two different people cannot deploy the same contract with the same address that is derived from the same preCode

BUG: updating rust

Today @fredfortier reported build errors appearing seemingly out of the blue from a dependency, that we checked were system independent but related to an older version of rust that this image was running. If we updated to a much newer version other errors would appear, so "locking" Rust to this version nightly-2018-11-01 fixed these build errors.

For the record, this is a failed build before this fix:

~/src/enigma-core# make JOBS=1 DEBUG=1
mkdir -p ./lib
make -C ./enclave/ CARGO_FLAGS=-j1 Rust_target_dir=debug
make[1]: Entering directory '/root/src/enigma-core/enclave'

Update rust-toolchain to nightly-2019-05-22

rust-toolchain file doesn't match baidu's toolchain https://github.com/baidu/rust-sgx-sdk/commit/e0fa56e7deca38fdba3797b345a0a46b696edd8b

This should also fix the annoying no_mangle warnings https://github.com/rust-lang/rust/issues/60050

Move code output from verbosity level 2 to 3

Is your feature request related to a problem? Please describe. When running the the integration integration test on Travis (and trying to integrate the integration tests with other repos on Travis), Travis reports Log Length exceeded and aborts before the tests finish.

In the current setup core runs with -vv. If I change the verbosity level to -v the tests succeed, but I don't have enough visibility to what core does to be able to troubleshoot.

Describe the solution you'd like When you choose verbosity level 2 with -vv, when deploying a contract (message Ok(DeploySecretContract...) would not include the output field that contains the bytecode of the deployed contract, but would include all other fields.

The, to display the field above with all others, you would choose -vvv.

ENG:SCRT swap ratio

A selected few validators have suggested that the large community wants a 1:1 swap between ENG:SCRT. I believe this to be a false narrative. In order to quantify my gut feeling, I have created a simple poll to get an idea of what the community wants.

Please cast your vote here.

Refactoring the KM

Changed naming. Error Handling. Removed unnecessary structs. made the code a bit more rustic. The Integration tests are failing, work is needed to be done in order to locate the cause and fix it.

Undocument Prefix After Decrypting Outputs of a computation

Describe the bug Decrypting the output of a computation includes a prefix, at least when he results are Vec<u8>. What is it used for?

To Reproduce See example here: https://github.com/enigmampc/coinjoin-poc/blob/65350409f4dbf43eeb178904cec3ca25e7e5070e/enigma-coinjoin-operator/src/secretContractClient.js#L86

Let me know if you need more contexts. Hackaton participants have observed the same thing. They also had trailing zeros which weren't in the returned Vec<u8> variable.

Expected behavior No prefix or an explanation of what the prefix means.

Compilation Error `bytes32` type in Eth Contracts

I'm getting a compilation error when compiling a secret contract that references a smart contract. I followed an elimination process to determine what in the smart contract abi causes the error and bytes32 seems to be the culprit.
