    Abstract: Techniques for rapidly delivering broadcasted live content are described. In an example, a transaction request to create placeholder non-fungible tokens (NFTs) in a token repository (106) is sent, where NFTs represent unique digital items. In response to the transaction request, an address allocated to a placeholder NFT from the plurality of placeholder NFTs in the token repository (106) is received. A notification indicating availability of the piece of live content is then transmitted to a user device (102), where the notification is indicative of the address allocated to the placeholder NFT in the token repository (106). In the meantime, a unique representation of the piece of live content is generated and populated on the token repository (106).

    Abstract: A media device receives a domain key from a service provider. The media device further encrypts media with a media key and encrypts the media key with the domain key to form an encrypted media token: the protected media key is encapsulated in an encrypted media token. The service provider may then receive the encrypted media token and one or more receiving entity identifiers relating to a receiving entity and ascertain whether the receiving entity is entitled to access media from the media device. If the receiving entity is entitled to access media from the media device, the service provider decrypts the cryptographic media token using the domain key to obtain the media key and providing the media key to the receiving entity. As such, an authenticated receiving entity may obtain the media key necessary to decrypt the media. Moreover, there is no requirement for any intermediate entity to have similar access and thus the encryption provided by the media key is in place throughout the transport of the media from media device to receiving entity.

    Abstract: Techniques for a smartphone-based conditional access (CA) system are described. In some embodiments, a headend in the CA system obtains a security profile associated with a pair of receiving devices used by a user, e.g., a first device (e.g., a smartphone) and a second device (e.g., a set-top-box or a TV). The headend dynamically regulates user access to requested media content during each entitlement period by assigning and distributing separate keys to the first and second device based on the security profile. The headend also uses the distributed keys to protect the media content before broadcasting. On the receiving end, one receiving device receives the media content and determines whether it is decryptable by the device. If decryptable, the receiving device (e.g., the set-top-box/TV) decrypts the media content using the keys assigned by the headend. Otherwise, the receiving device forwards the media content to the pairing device for decryption.
