Designing PIC-X: Deriving an Initial PIC Context of Authority.
Designing PIC-X. Deriving an Initial PIC Context of Authority.

PIC-X receives an OAuth access token at the selected realm token endpoint, validates it, and derives the initial PIC Context of Authority, or PCA. A PCA is the logical Context of Authority. Its signed representation is a PIC PCA COSE. PIC-X then returns a realm-signed PIC Token JWT carrying a settled PIC Continuity COSE in pic.root.
