Abstract: In one embodiment, an apparatus comprising a memory to store a first value of a cryptographic key state; and a processor to generate a request to commit the first value of the cryptographic key state into a block of a blockchain, the blockchain to synchronize the cryptographic key state for a plurality of security modules; and generate a one-time cryptographic key based on the first value of the cryptographic key state responsive to a determination that the first value of the cryptographic key state has been committed to the blockchain.

Abstract: The present disclosure is directed to content protection for Data as a Service (DaaS). A device may receive encrypted data from a content provider via DaaS, the encrypted data comprising at least content for presentation on the device. For example, the content provider may utilize a secure multiplex transform (SMT) module in a trusted execution environment (TEE) module to generate encoded data from the content and digital rights management (DRM) data and to generate the encrypted data from the encoded data. The device may also comprise a TEE module including a secure demultiplex transform (SDT) module to decrypt the encoded data from the encrypted data and to decode the content and DRM data from the encoded data. The SMT and SDT modules may interact via a secure communication session to validate security, distribute decryption key(s), etc. In one embodiment, a trust broker may perform TEE module validation and key distribution.

Abstract: Techniques for allowing devices to obtain software updates are described. In one scenario, a device broadcasts request for updates to nearby devices of the same type, at least one of which responds indicating an available update. The device requesting the update broadcasts a request for the available update to nearby devices, at least one of which provides at least a portion of the update. In another scenario, a device broadcasts requests for update to nearby devices manufactured by the same manufacturer. At least one device may provide the update, responsive to a determination that the update is available. Alternately, responsive to a determination that the update is not available, the device receiving the broadcast may respond saying the update is not available, then attempt to update the update from an update server. Upon receiving a later broadcast, the device having the update may provide the update to the requesting device.
