Abstract: This disclosure relates to, among other things, managing data communicated between systems, services, and/or devices using explicit private networking techniques that provide relatively robust end-to-end security. In some embodiments, explicit private networking techniques may protect data in transit and/or as at rest and/or in use in potentially hostile environments. In various embodiments, an explicit private networking techniques architecture may protect connected device data where and when it is generated by encrypting it and maintaining that protection until it is consumed in a trusted information platform and/or service that uses identity and access management services to identify, authenticate, and/or authorize permissions to read, modify, and/or collaborate with that data and/or control devices and/or issue associated device commands.

Abstract: Systems and methods are described for securely and efficiently processing electronic content. In one embodiment, a first application running on a first computing system establishes a secure channel with a second computing system, the secure channel being secured by one or more cryptographic session keys. The first application obtains a license from the second computing system via the secure channel, the license being encrypted using at least one of the one or more cryptographic session keys, the license comprising a content decryption key, the content decryption key being further encrypted using at least one of the one or more cryptographic session keys or one or more keys derived therefrom.

Abstract: This disclosure relates to, among other things, systems and methods for deriving key identifiers and managing mapping between keys and key identifiers. Consistent with embodiments disclosed herein, the disclosed systems and methods may provide a mechanism that allows multiple parties to reconstruct unique identifiers given a set of known inputs that may be used to look up, identify, and/or otherwise access services and/or data objects. In some embodiments, this may allow for a service provider and a rights management service to independently derive key identification information based on information that both entities share (e.g., a content document such as a Content Protection Information Exchange Format document), thereby reducing requirements to maintain such mappings.

Abstract: This disclosure relates to, among other things, systems and methods for the secure management and distribution of electronic content over broadcast communication channels. Certain embodiments disclosed herein may allow for implementation of a multi-tenant conditional access system whereby a client device may configure itself between multiple broadcast service operators. Robust key generation and management techniques are also described that may use a derived key structure to protect control words used to descramble broadcast content, providing additional measures of security and implementation redundancy.

Abstract: This disclosure relates to, among other things, systems and methods for managing the secure management and distribution of electronic content over broadcast and/or broadband communication channels. Certain embodiments disclosed herein may allow for implementation of a digital rights management service in connection with bidirectional communication channels and/or unidirectional communication channels, such as a broadcast signal. Various embodiments may allow for the generation and/or transmission of a digital rights management license in a field included in a broadcast signal. The license may be used by a client device to securely manage a received broadcast signal in accordance with associated rules and/or rights.

Abstract: Systems and methods are described that use tag authentication and presence verification techniques in connection with a variety of transactions. In certain embodiments, an authentication device may verify the authenticity of a secure tag by determining whether the secure tag stores secret information provisioned by a trusted authority. In some embodiments, such an authentication process may be performed without exposing the secret information to the authentication device, thereby maintaining integrity of the secure tag. In other embodiments, insecure tags and/or tags that do not include secret information are used.
