encrypt the second signature with a second private key; and

add the second signature to the supplemental license response.

11. The apparatus of claim 10 wherein the generating the second signature is further based on the second public key and the first check signature.

12. The apparatus of claim 10 wherein the one or more processors are further configured to be capable of executing the stored programmed instructions to transmit the supplemental license response in response to an initial license request with the registration identifier.

13. A non-transitory computer readable medium having stored thereon instructions for securing one or more entitlement grants comprising machine executable code which when executed by one or more processors, causes the one or more processors to:

transmit a registration license request encrypted with a first public key to a license server, the registration license request comprising a registration identifier and a second public key;

receive a registration license response from the license server, the registration license response comprising one or more license entitlement grants, the second public key, and a first secure signature encrypted with a first private key, the first secure signature is based on at least the one or more license entitlement grants;

generate a first check signature based on at least the one or more license entitlement grants and the second public key;

decrypt the first encrypted secure signature with the first public key to obtain the first decrypted secure signature; and

authenticate and provide integrity of the one or more license entitlement grants when the first decrypted secure signature matches the first check signature.

14. The medium of claim 13 wherein the first secure signature and the first check signature are each further based on the second public key and are each a hash sum of at least the one or more license entitlement grants and the second public key.

15. The medium of claim 13 wherein the executable code when executed by the one or more processors further causes the one or more processors to:

add a dossier of one or more authorized client devices to a supplemented license response.

16. The medium of claim 15 wherein the executable code when executed by the one or more processors further causes the one or more processors to:

generate a second signature based on at least the one or more license entitlement grants and the dossier;

encrypt the second signature with a second private key; and

add the second signature to the supplemental license response.

17. The medium of claim 16 wherein the generating the second signature is further based on the second public key and the first check signature.

18. The medium of claim 16 wherein the executable code when executed by the one or more processors further causes the one or more processors to:
