Claim 3:
4. The method of claim 3, wherein validating the second data packet based on the first error detecting code value and the second error detecting code value comprises, at the sink device comprising the third microcontroller further pre-programmed with the second key associated with the second microcontroller:
appending the first key to the payload;
in response to appending the first key to the payload, generating the third error detecting code value based on the payload and the first key;
appending the second key to the payload;
generating a fourth error detecting code value based on the payload and the second key; and
validating the second data packet in response to verifying a match between the fourth error detecting code value and the second error detecting code value.
