pub struct Garbler<C, RNG, Wire> { /* private fields */ }
Expand description

Streams garbled circuit ciphertexts through a callback.

Implementations

Create a new garbler.

Create a delta if it has not been created yet for this modulus, otherwise just return the existing one.

Get the deltas, consuming the Garbler.

This is useful for reusing wires in multiple garbled circuit instances.

Send a wire over the established channel.

Encode a wire, producing the zero wire as well as the encoded value.

Encode many wires, producing zero wires as well as encoded values.

Encode a CrtBundle, producing zero wires as well as encoded values.

Encode a BinaryBundle, producing zero wires as well as encoded values.

Trait Implementations

The underlying wire datatype created by an object implementing Fancy.
Errors which may be thrown by the users of Fancy.
Create a constant x with modulus q.
Process this wire as output. Some Fancy implementers don’t actually return output, but they need to be involved in the process, so they can return None. Read more
Output a slice of wires.
Add x and y.
Subtract x and y.
Multiply x times the constant c.
Multiply x and y.
Project x according to the truth table tt. Resulting wire has modulus q. Read more
Sum up a slice of wires.
Change the modulus of x to to_modulus using a projection gate.

We can negate by having garbler xor wire with Delta

Since we treat all garbler wires as zero, xoring with delta conceptually negates the value of the wire

Xor is just addition

Use binary and_gate

Uses Demorgan’s Rule implemented with an and gate and negation.
Binary adder. Returns the result and the carry.
Returns 1 if all wires equal 1.
Returns 1 if any wire equals 1.
XOR many wires together
If x = 0 returns the constant b1 else return b2. Folds constants if possible.
If b = 0 returns x else y.
