Efficient RBE [GKMR23] on Ethereum

EVM Registration-Based Encryption

Efficient Registration-Based Encryption (RBE) [GKMR23] on Ethereum.

The core smart contract implementing the Key Curator is in contracts/KeyCurator.sol.

The remainder of the system is run off-chain in Rust, with computations implemented in src/ and tested in tests/.

Dependencies

• Solc
• Foundry (includes Anvil)

Usage

• Install: forge install
• Build: cargo build
  • This also compiles the contracts to JSON
• Test:
  • Solidity tests: forge test
  • Rust tests: cargo test

Credits

• EC arithmetic via arkworks-rs, usage here
• The Solidity library for EC precompiles, much of the repo structure, and parts of the Rust code were based on/taken from a16z's powers of tau implementation
