Struct SdlsProcessor 

pub struct SdlsProcessor<C> { /* private fields */ }

SDLS-based security processor (CCSDS 355.0-B-2).

Wraps a SecurityAssociation and CryptoProvider to implement in-place frame encryption and authentication.

The header_end offset tells the processor where the transfer frame header ends (5 for TC, 6 for TM). The security header is inserted at that offset, followed by the encrypted data field and optional MAC trailer.

Implementations

impl<C: CryptoProvider> SdlsProcessor<C>

pub fn new(sa: SecurityAssociation, crypto: C, header_end: usize) -> Self

Creates a new SDLS processor.

header_end is the byte offset where the transfer frame header ends (5 for TC, 6 for TM).

pub fn sa(&self) -> &SecurityAssociation

Returns a reference to the security association.

pub fn sa_mut(&mut self) -> &mut SecurityAssociation

Returns a mutable reference to the security association.

Trait Implementations

impl<C: CryptoProvider> SecurityProcessor for SdlsProcessor<C>

type Error = Error

Error type for security operations.

fn apply(&mut self, frame: &mut [u8]) -> Result<usize, Self::Error>

Applies security (encrypt/authenticate) to a frame in-place.

fn process(&mut self, frame: &mut [u8]) -> Result<usize, Self::Error>

Removes security (decrypt/verify) from a frame in-place.
