Struct Verifier 

pub struct Verifier { /* private fields */ }

Verifies signed v2 frames against a shared key, rejecting forged and replayed frames.

A verifier recomputes each frame’s signature and rejects it unless it matches. It also enforces freshness: a frame from a stream it has seen must carry a strictly newer timestamp than the last, and a frame from a new stream must not be more than the replay window behind the newest timestamp seen, so a recording of an old frame cannot be re-injected.

Implementations

impl Verifier

pub fn new(key: [u8; 32]) -> Self

Creates a verifier for a key, using the default replay window.

Arguments

• key - the 32-byte shared secret.

Returns

The verifier.

pub fn with_window(self, window: u64) -> Self

Sets the replay window, in 10-microsecond ticks.

Arguments

• window - how far behind the newest accepted timestamp a frame from a new stream may be.

Returns

The verifier, for chaining.

pub fn verify(&mut self, frame: &Frame) -> Result<()>

Verifies a signed frame’s signature and freshness.

On success, the frame’s stream timestamp is recorded so a later replay of the same or an older frame is rejected.

Arguments

• frame - the parsed frame to check.

Returns

Ok(()) if the frame is authentic and fresh.

Errors

Returns MavlinkError::Unsigned if the frame is not signed, MavlinkError::BadSignature if the signature does not match the key, or MavlinkError::ReplayedTimestamp if the timestamp is not fresh.

Trait Implementations

impl Clone for Verifier

fn clone(&self) -> Verifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.
