  • Publication number: 20200364318
    Abstract: A game identifier of an encrypted streaming electronic game to be streamed to a playback device may be received. The game identifier may comprise a title of the encrypted streaming electronic game. An electronic ticket for access by the playback device to a secured portion of the encrypted streaming electronic game may be gathered. The electronic ticket may specify a first gameplay state. The electronic ticket may be used to access the secured portion of the encrypted streaming electronic game at the first gameplay state. One or more gameplay actions to transform the encrypted streaming electronic game to a second gameplay state may be received. The second gameplay state may be provided to a state server, where the state server configured to instruct a license server to modify the electronic ticket to specify the second gameplay state for the encrypted streaming electronic game.

  • Patent number: 10664575
    Abstract: A technique for content management involves storing runtime state of content externally. A system created according to the technique may include a state server that receives runtime state of content from a playback device, and provides the runtime state to that or another playback device upon request. A playback device constructed according to the technique may include a content state recovery engine for recovering runtime state that was previously stored externally to the playback device. A method according to the technique may include generating the runtime state locally, storing the runtime state externally, and re-acquiring the runtime state.

  • Publication number: 20180137307
    Abstract: A method may be executed by a secure processor having secure cryptography hardware implemented thereon. The method may be executed in a security kernel of a secure on-chip non-volatile (NV) memory coupled to the secure processor. The method may include: storing a rewritable state and a device private key based at least in part on a programmed secret seed and the rewritable state, the device private key being part of a cryptographic key pair comprising a public key associated with the device private key, and the rewritable state being a state of a secure application encrypted with the public key; providing one or more instructions to gather the device private key and from the private key datastore; and using the device private key to generate a device certificate, the device certificate providing the device with access to the secure application.

  • Patent number: 9589154
    Abstract: An improved secure programming technique involves reducing the size of bits programmed in on-chip secret non-volatile memory, at the same time enabling the typical secure applications supported by secure devices. A technique for secure programming involves de-coupling chip manufacture from the later process of connecting to ticket servers to obtain tickets. A method according to the technique may involve sending a (manufacturing) server signed certificate from the device prior to any communication to receive tickets. A device according to the technique may include chip-internal non-volatile memory to store the certificate along with the private key, in the manufacturing process.

  • Patent number: 8200961
    Abstract: A technique for securing a flash memory block in a secure device system involves cryptographic techniques including the generation of a Message Authentication Code (MAC). The MAC may be generated each time a file is saved to one or more data blocks of a flash memory device and stored with the file's metadata and to each of the data blocks. A technique for reading and storing versioned files may be employed when applications utilize versioning.
