Abstract:

   The Supply Chain Integrity, Transparency, and Trust (SCITT)
   architecture permits distinct Issuers to agree on the same CBOR Web
   Token (CWT) Subject Claim (sub) value for a common Subject.  This
   document specifies one profile by which those Issuers can
   independently compute that common value from the same application-
   defined Subject semantics without relying on a shared assigning
   authority.

   A surrounding application maps its Subject description to an admitted
   structured Value.  This profile defines an exact deterministic
   binding encoding, SHA-256 derivation, a text representation, and
   verification requirements for deriving sub from that Value.  Optional
   JSON and Concise Binary Object Representation (CBOR) forms are
   provided for exchanging an admitted Value; they are not SCITT
   Statement payload formats.  The SCITT Statement payload, signature,
   Registration, Receipt, Transparency Service state, and Issuer
   identity are not implicit inputs to Subject derivation.
