Functions ¶
func DecodePlaintextOutputLabels ¶
this is decoding for a GC scheme where output is NOT encrypted
func GenerateWireLabels ¶
func GenerateWireLabels(labelSet *SimpleWireLabelSet, freeXORDelta Label_t, rand *rand.Rand, isStructured bool) bool
Generates two free-XOR enabled wire labels of length LABEL_LEN_BYTES isStructured refers to how the label is constructed -- in the case of output gates the label must have the last bit correspond to actual output in the case of our scheme being anonymous
Types ¶
type Ciphertext_t ¶
type Ciphertext_t []byte
type Circuit ¶
type Circuit struct {
// Total number of input and output wires

Gates []Gate
}
func (*Circuit) DecodeOutputVariables ¶
Convert an evaluated array of boolean wire values into binary fields, one for each output variable in the circuit
func (*Circuit) EvaluateCircuit ¶
Circuit evaluation on concrete inputs. Returns success/failure and a list of output bits. Inefficient algorithm used for testing.
func (*Circuit) PadInputsToBoolArray ¶
Convert an array of []byte values into a boolean array that's bit-aligned with the circuit inputs
type CryptoSource ¶
type CryptoSource struct{}
Assemble a PRNG from the cryptographic CSPRNG, man this is a bad hack I got off the Internet -- TODO make it better <-- Gabby modifiying so that this can be used also in the standalone library
