Struct JoinServerKeys 

pub struct JoinServerKeys {
    pub js_int_key: JSIntKey,
    pub js_enc_key: JSEncKey,
}

Join Server keys (LoRaWAN 1.1) derived from NwkKey and DevEUI.

Used by the Join Server (not the device) for Rejoin-aware Join Accept signing and re-encryption. Pair of keys; see JoinServerKeys::derive.

Fields

js_int_key: JSIntKey

Integrity key for Join Accept and Rejoin Type 1 MIC.

js_enc_key: JSEncKey

Encryption key for re-encrypting Join Accept bodies sent to rejoining devices.

Implementations

impl JoinServerKeys

pub fn derive(nwk_key: &NwkKey, dev_eui: &DevEui) -> Self

Derive both JS keys from NwkKey and DevEUI.

Examples

use lora_packet::{JoinServerKeys, NwkKey, DevEui};

let nwk_key = NwkKey::new([0x42u8; 16]);
let dev_eui = DevEui::new([0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77, 0x88]);
let js = JoinServerKeys::derive(&nwk_key, &dev_eui);
assert_ne!(js.js_int_key.as_bytes(), js.js_enc_key.as_bytes());
