XXXEncryptSharedSecret constructs a SharedSecretEncryptions from a set of SharedSecretEncryptionPublicKeys, the sharedSecret, and a cryptographic randomness source.

XXXEncryptSharedSecretInternal constructs a SharedSecretEncryptions from a set of SharedSecretEncryptionPublicKeys, the sharedSecret, and an ephemeral secret key sk.

A 128-bit symmetric key.

PublicConfig is the configuration disseminated through the smart contract It's public, because anybody can read it from the blockchain.

SharedConfig is the configuration shared by all oracles running an instance of the protocol.

SharedSecretEncryptions is the encryptions of SharedConfig.SharedSecret, using each oracle's SharedSecretEncryptionPublicKey.
