Claim 6:
7. A data receiver comprising:
a microcontroller or a system-on-a-chip configured to:
in response to receiving a series of one or more packets carrying a set of data and a remotely-generated digest of the set of data generated using a cryptographic primitive, where each packet in the series includes a header, the set of data, a footer and the remotely-generated digest positioned between the footer and the set of data, extract the set of data and extract the remotely-generated digest;
generate a locally-generated digest from the set of data using the same cryptographic primitive used to generate the remotely-generated digest; and
compare the remotely-generated digest and the locally-generated digest and signal whether the remotely-generated digest and the locally-generated digest are the same or different so as to indicate an absence or presence respectively of a transmission error.
