AUTOSAR E2E Protection Library

This library implements the AUTOSAR E2E (End-to-End) protection mechanism as specified in the AUTOSAR standard.

Overview

The E2E protection mechanism provides end-to-end data protection for safety-critical automotive communication. It detects errors in data transmission including:

• Data corruption (via CRC)
• Message loss, duplication, or reordering (via sequence counter)
• Incorrect addressing (via Data ID)

Example

use autosar_e2e::{E2EProfile, E2EResult};
use autosar_e2e::profile11::{Profile11, Profile11Config, Profile11IdMode};

// Create a Profile 11 configuration
let config = Profile11Config {
    mode: Profile11IdMode::Nibble,
    max_delta_counter: 1,
    data_length: 40,
    ..Default::default()
};

// Create the profile instance
let mut profile = Profile11::new(config)?;

// Protect data
let mut data = vec![0x00, 0x00, 0x12, 0x34, 0x56]; //[CRC, counter, user data ..]
profile.protect(&mut data)?;

// Check protected data
let status = profile.check(&data)?;
