Meaning
Cryptographic container sections hold the raw data intended for transmission within an authenticated envelope. The cose payload contains the information after it has been correctly formatted into cbor for transit across low power networks. It rests separately from the header fields that describe the hashing algorithm or signing identity used.
Data Structure
Measurement scripts count the size of the packet to verify it fits within maximum transmission unit limits of constrained protocols. Designing a cose payload involves selecting which data points are included in the protection zone and which remain external for public visibility. If the contents exceed the capability of the local buffer, truncation issues occur during processing.
Security Wrapping
Integrity checks confirm that the bits inside have not been altered since the message left the gateway. Because the cose payload is the primary target of the signature, every byte within it is covered by the mathematical verification check. Success in authentication confirms that the data has reached its destination intact.
Content Capability
Industrial systems transmit sensor readings and control commands as standard message types. Identifying the cose payload helps the receiving system determine what logic to apply once the decryption or verification succeeds. It serves the specific need of delivering clean data entries.
