Abstract

An architecture is described to manufacture console-based gaming systems in a manner that allows them to be authenticated to a remote entity for online participation. The architecture involves placing pre-established secrets on the game console during console manufacturing that may be subsequently used to guarantee the authenticity of the game console during registration time.

Claims

1. A method for manufacturing a game console having at least programmatically accessible memory and network interfacing capability to enable access to a network, comprising:

writing a symmetric key in the programmatically accessible memory in the game console;

encrypting the symmetric key to produce an encrypted symmetric key; and

maintaining the encrypted symmetric key in a database separate from the game console.

2. A method as recited in claim 1, wherein the encrypting comprises encrypting the symmetric key using a public key cipher and a public key of a public key pair.

3. A method as recited in claim 1, wherein the encrypting comprises encrypting the symmetric key using a symmetric key cipher.

4. A method as recited in claim 1, further comprising randomly generating the symmetric key.

5. A method as recited in claim 1, further comprising:

assigning a console ID to each game console;

writing the console ID in the programmatically accessible memory; and

maintaining the console ID in the database in association with the encrypted symmetric key.

6. A method as recited in claim 1, further comprising transferring the encrypted symmetric key to a data center that is used to authenticate the game console.

7. One or more computer-readable media comprising computer-executable instructions that, when executed, perform the method as recited in claim 1.

8. A method for manufacturing a game console having at least programmatically accessible memory and network interfacing capability to enable access to a network, comprising:

generating a console public key pair associated with a game console, the console public key pair having a console public key and a corresponding console private key;

creating a certificate chain of digital certificates starting from a root certificate signed by a root private key and ending at a console certificate, the console certificate containing the console public key; and

storing the console certificate and the console private key in the programmatically accessible memory in the game console,

wherein the acts of generating, creating and storing are part of at least one of a pre-manufacturing process and a manufacturing process of a game console.

9. A method as recited in claim 8, wherein the certificate chain further includes a certification authority (CA) certificate intermediate of the root certificate and the console certificate, the CA certificate being signed by the root private key and containing a CA public key from a CA public key pair, the CA public key pair having a corresponding CA private key that is used to sign the console certificate.

10. One or more computer-readable media comprising computer-executable instructions that, when executed, perform the method as recited in claim 8.

11. A computer-readable medium comprising computer-executable instructions that, when executed, direct a computing system to:

write a randomly generated symmetric key and a console ID into a programmatically accessible memory in a game console, the game console having network interfacing capability to enable access to a network;

encrypt the symmetric key to produce an encrypted symmetric key; and

store the encrypted symmetric key and the console ID in a database separate from the game console.

12. A computer-readable medium as recited in claim 11, further comprising computer-executable instructions that, when executed, direct the computing system to encrypt the symmetric key using a public key of a public key pair.

13. A computer-readable medium as recited in claim 11, further comprising computer-executable instructions that, when executed, direct the computing system to transmit the symmetric key and/or proof of knowledge of the symmetric key and the console ID to a data center used to authenticate the game console.

14. A computer-readable medium comprising computer-executable instructions that, when executed, direct a computing system to:

generate a root public key pair having a root public key and a corresponding root private key;

generate a certificate chain from a root certificate signed by the root private key to a console certificate associated with a game console having at least programmatically accessible memory and network interfacing capability to enable access to a network, the console certificate containing a console public key from a console public key pair; and

write the console certificate and a console private key corresponding to the console public key in the programmatically accessible memory of the game console,

wherein the instruction to write the console certificate and the console private key is to occur during a manufacturing process of a game console.
