Dynamic utilization of condensing metadata is enabled by condensing information being communicated to/from a mobile device. The communication exchange occurs between a mobile device and an internet service, and it involves a mobile internet service proxy. The information is condensed or compressed responsive to condensing metadata and uncondensed or uncompressed using the condensing metadata. The mobile internet service proxy may provide condensing metadata to the mobile device. This condensing metadata may be provided to the mobile device so that condensed data may be communicated at least between the mobile device and the mobile internet service proxy. In some instances, the mobile device may request that information be compressed and receive compressed information as a result. The mobile device may then utilize the condensing metadata to uncompress data provided from the internet service and/or the mobile internet service proxy.

Dynamic Utilization of Condensing Metadata

Systems and methods for managing a content encryption key and a seed to generate the content encryption key are provided. In one example, a method may include receiving a request for a content encryption key at a content encryption key service. The request includes a requesting entity fingerprint that corresponds to a requesting entity and a seed identifier that corresponds to a seed. The seed identifier is mapped to the seed and the requesting entity fingerprint mapped to a corresponding seed permission. If the seed permission entitles the requesting entity to receive the content encryption key, the key is derived using the seed and provided to the requesting entity.

Content encryption key management

Security protocols for mobile operator networks are described. In embodiments, mobile communication link is established between a mobile phone and a media content provider via a communication service provider with which the mobile phone is registered for mobile communications, and via at least one roaming node network with which the communication service provider has a roaming service agreement. The media content provider receives a security policy request from the mobile phone to establish a security policy for end-to-end security of the mobile communication link between the media content provider and the mobile phone for data communication security. The media content provider then communicates a security policy response to the mobile phone to establish the security policy for the end-to-end security of the mobile communication link that is adaptable to security restrictions of the roaming node network.

Dynamic utilization of condensing metadata is enabled by condensing information being communicated to/from a mobile device. The communication exchange occurs between a mobile device and an internet service, and it involves a mobile internet service proxy. The information is condensed responsive to condensing metadata and uncondensed using the condensing metadata. In an example embodiment, condensing metadata comprises encoding metadata for tags and compression metadata for other data. In a first described implementation, a mobile internet service proxy effectuates a static installation of condensing metadata to the mobile device from the internet service. In a second described implementation, the internet service lacks condensing metadata. The mobile internet service proxy therefore retrieves the schema defining the relevant information and dynamically generates condensing metadata. This dynamically-generated condensing metadata is copied to the mobile device so that condensed data may be communicated at least between the mobile device and the mobile internet service proxy.
