Abstract
A method includes receiving, by a server computer, a thin client identifier from a thin client on a communication device. The server computer can then retrieve an encrypted first cryptographic key based on the thin client identifier. The encrypted first cryptographic key is a first cryptographic key that is encrypted with a second cryptographic key. The server computer can initiate the sending of the encrypted first cryptographic key to the thin client. The server computer then receives an encrypted secret from the thin client, the encrypted secret being a secret encrypted with the first cryptographic key.
