  • receiving, by a client computing machine, a token comprising a first applet, a first symmetric key set associated with the first applet and a card identification number of the token;

    authenticating, by the client computing machine, with the first applet on the token using the first symmetric key set to establish access to the first applet;

    generating, by the client computing machine, a second symmetric key set based on a private cryptographic key and the card identification number of the token in response to authenticating with the first applet;

    associating, by the client computing machine, the second symmetric key set with the first applet; and

    severing, by the client computing machine, the association between the first symmetric key set with the first applet.
