Function DeriveNwkSEncKey

pkg/crypto/key_derivation.go:58–60

DeriveNwkSEncKey derives the LoRaWAN 1.1 Network Session Encryption Key

(nwkKey types.AES128Key, jn types.JoinNonce, joinEUI types.EUI64, dn types.DevNonce)

// DeriveNwkSEncKey derives the LoRaWAN 1.1 Network Session Encryption Key
func DeriveNwkSEncKey(nwkKey types.AES128Key, jn types.JoinNonce, joinEUI types.EUI64, dn types.DevNonce) types.AES128Key {
	return deriveSKey(nwkKey, 0x04, jn, joinEUI, dn)
}

// DeriveAppSKey derives the LoRaWAN Application Session Key
// - If a LoRaWAN 1.1 device joins a LoRaWAN 1.1 network, the AppKey is used as "key"
