Abstract: A first verifiable credential is received at a second entity from a first entity. The first verifiable credential is cryptographically signed by the first entity using decentralized identifier (DID) of the first entity. The first verifiable credential includes a security indicator that specifies a security posture of the second entity based on security settings implemented by the second entity. A second verifiable credential is generated that embeds the first verifiable credential therein. The second verifiable credential is provided to a third entity. The second verifiable credential causes the third entity to verify the cryptographic signature of the first entity with a public key associated with the DID of the first entity to determine that the first verifiable credential is valid and that the security settings being implemented by the second entity are in compliance with security policies of the third entity.
