1. A method to allow at least one party to perform at least one permitted activity with respect to a device, comprising the steps of:
- embedding a role certificate in said device, wherein the role certificate identifies said at least one permitted activity and wherein the role certificate is generated by a Certification Authority (CA);
embedding at least information regarding a public key in said device the public key corresponding to the private key used by the CA to sign the role certificate; and
running the device so as to verify the role certificate using said information regarding the CA public key so that said at least one permitted activity can be activated within the device by said at least one party if the role certificate is verified.
