Abstract:
COSE (CBOR Object Signing and Encryption) Receipts prove properties
of a verifiable data structure to a verifier. Verifiable data
structures and associated proof types enable security properties,
such as minimal disclosure, transparency and non-equivocation.
Transparency helps maintain trust over time, and has been applied to
certificates, end to end encrypted messaging systems, and supply
chain security. This specification enables concise transparency
oriented systems, by building on CBOR (Concise Binary Object
Representation) and COSE. The extensibility of the approach is
demonstrated by providing CBOR encodings for Merkle inclusion and
consistency proofs.
