ABSTRACT:
A method of authenticating a PSD and an initializing infrastructure that uses a secret key, a PSD public/private key pair and a provider public/private key pair. The infrastructure prepares a signed provider key record using the provider public key and the provider private key and a first MAC using the signed provider key record and the secret key. Both are sent to the PSD. The PSD authenticates the signed provider key record using the first MAC and the provider public key using the included digital signature. The PSD prepares a signed PSD key record using the PSD public key and the PSD private key and a second MAC using the signed PSD key record and the secret key. Both are sent to the infrastructure. The infrastructure authenticates the signed PSD key record using the second MAC and the PSD public key using the included digital signature.
