Abstract
A data transmitter is disclosed. The data transmitter includes a digest generator configured in response to receiving a set of data from a data source to generate a digest from the set of data using a cryptographic primitive. The data transmitter further includes a packet generator configured to generate a series of one or more packets carrying the set of data for transmission, wherein each packet in the series includes a header, the set of data, a footer and the digest.
Claims8
A data transmitter comprising:
- an integrated circuit configured to:
- in response to receiving a set of data from a data source, generate a digest from the set of data using a cryptographic primitive;
- and
- generate a series of one or more packets carrying the set of data for transmission,
- wherein each packet in the series includes a header, the set of data, a footer and the digest, and
- wherein the digest is positioned between the footer and the set of data.
3 more elements
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.
