Struct OneTimePadFhe 

pub struct OneTimePadFhe<const BLOCK_BYTES: usize>;

Parametric one-time-pad “FHE” — additive over ciphertexts under XOR.

Reference impl suitable for conformance testing the axis dispatch path; not a cryptographic FHE scheme. BLOCK_BYTES is the ciphertext block width. Production FHE schemes (TFHE, BGV, CKKS per ADR-031’s roster) are application-level integrations that satisfy the same FheAxis contract with cryptographically secure schemes.

Trait Implementations

impl<const BLOCK_BYTES: usize> AxisExtension for OneTimePadFhe<BLOCK_BYTES>

const AXIS_ADDRESS: &'static str = <OneTimePadFhe<BLOCK_BYTES> as FheAxis>::AXIS_ADDRESS

ADR-017 content address of this axis trait. The SDK macro derives this from the trait name and method signatures.

const MAX_OUTPUT_BYTES: usize = <OneTimePadFhe<BLOCK_BYTES> as FheAxis>::MAX_OUTPUT_BYTES

Maximum bytes any kernel of this axis returns.

fn dispatch_kernel( kernel_id: u32, input: &[u8], out: &mut [u8], ) -> Result<usize, ShapeViolation>

Dispatch the kernel identified by kernel_id against the evaluated input bytes. The implementation copies the kernel’s output into out and returns the written length.

impl<const BLOCK_BYTES: usize> Clone for OneTimePadFhe<BLOCK_BYTES>

fn clone(&self) -> OneTimePadFhe<BLOCK_BYTES>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<const BLOCK_BYTES: usize> Debug for OneTimePadFhe<BLOCK_BYTES>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<const BLOCK_BYTES: usize> Default for OneTimePadFhe<BLOCK_BYTES>

fn default() -> OneTimePadFhe<BLOCK_BYTES>

Returns the “default value” for a type.

impl<const BLOCK_BYTES: usize> FheAxis for OneTimePadFhe<BLOCK_BYTES>

const AXIS_ADDRESS: &'static str = "https://uor.foundation/axis/FheAxis/OneTimePadReference"

const MAX_OUTPUT_BYTES: usize = BLOCK_BYTES

Ciphertext block width (overridden per impl).

fn add_ciphertexts( input: &[u8], out: &mut [u8], ) -> Result<usize, ShapeViolation>

Homomorphic addition of two ciphertext blocks. Input = c_a || c_b (2 * BLOCK_BYTES); output = c_a ⊕_FHE c_b.

impl<const BLOCK_BYTES: usize> SubstrateTermBody for OneTimePadFhe<BLOCK_BYTES>

fn body_arena() -> &'static [Term]

The Term arena the kernel decomposes to. Empty slice signals a primitive-fast-path axis whose body the implementation may evaluate through dispatch_kernel directly per ADR-055’s optional fast-path.
