in the section proof of possession we still have strict requirements about the cryptographic bindinds
Controlling a private key that corresponds to a public key associated
with the Credential, often indicated within the Credential's cnf
(confirmation) claim or through a similar mechanism.
The essence of requiring control over the private key and its
demonstration through a cryptographic operation
(e.g., signing a challenge or a token) is to ensure that the entity in
possession of the Credential can execute actions exclusively reserved
for the legitimate subject. The dual-layered approach of requiring both
possession of the Credential and control over the corresponding private
key indeed reinforces the security and integrity of the status assertion
process. It also ensures that the entity requesting a Status Attestation
is indeed the same entity to which the Credential was originally issued,
affirming the authenticity and rightful possession of the Credential.
