Abstract
A method for requesting a credential associated with token in a multiple token layer environment is disclosed. A tokenization certificate serves to validate the identity of a credential requestor and provide information about the requestor's authorization for de-tokenizing a token. Also, a public key in the tokenization certificate is used to encrypt the credential for secure transmission to the requestor.
