摘要： A digital rights management system (DRM) for restricting and permitting content access in a digital content distribution network such as a network used to deliver television programming. The DRM uses distributed authentication and provisioning so that the potentially many different entities involved in the content distribution network can have localized management and control. Distributed authentication can use single or multiple instances of authentication services. A ticket granting service (TGS) is used to allow clients to request services. In one approach, multiple authentication services use a common key that is known to the TGS. In another approach, unique keys are provided to each authentication service and these keys are communicated to the TGS. Distributed provisioning allows different entities to grant access rights or other resources. Provisioning service (PS) processes can execute at multiple different physical locations. Synchronization among the different PSs is provided by a managing entity or in a peer-to-peer transfer to help ensure the uniqueness of user IDs. New clients can make an initialization request from a key management system via an appropriate protocol. The requests can be made from a single, dedicated authentication service, from an authentication service associated with a specific provisioning service, or from multiple authentication services in the network.

摘要： A method and system (100) for providing third party authentication when requesting content and/or services from an application server (106). The method is applicable to key management protocols that utilize the concept of tickets. The method and system include a client (102) being coupled with a third party application server (107), wherein the client submits a request for content from the third party application server and the third party application server returns requested information and corresponding authentication. The client further couples with a first application server (106), wherein the client submits a key request (KEY_REQ) including the third party server information and corresponding authentication to the first application server. The first application server authenticates the third party server information and verifies client authorization based on third party information. The first application server returns a key reply (KEY_REP) if the third party server information is authenticated and client authorization is verified.

摘要： A method of authentication and authorization over a communications system is provided. Disclosed herein are systems and methods for creating a cryptographic evidence, called authentication/ authorization evidence, AE, when a successful authentication/ authorization between a client and an authentication server is complete. There are a variety of methods for generating AE. For instance, the AE can be data that is exchanged during the authentication signaling or data that results from it. A distinctive point being that AE results from the authentication process and is used as prior state for the following TLS exchange. An example for creation of AE, is as follows: EAP authentications typically result in an Extended Master Session Key (EMSK). The EMSK can be used to create an Evidence Master Key (EMK) that can then be used to create AE for a variety of servers.

摘要： A method for updating network-enabled devices with new identity data includes generating a plurality of new identity data records and loading the new identity data records onto an update server. A request is received at the update server for new identity data from at least one network-enabled device having a previously assigned identity linked to an identifier. The previously assigned identifier is linked to a new identifier that is linked to one of the new identity data records. One or more new identity data records are securely delivered to the network-enabled device.

摘要： A method of authentication and authorization over a communication system is provided. The method performs a first authentication of a device based on a set of device identity and credentials. The first authentication includes creation of a first set of keying material. The method also includes performing a second authentication of a subscriber based on a set of subscriber identity and credentials. The second authentication includes creation of a second set of keying material. A set of compound key material is created with a key derivation mechanism that uses the first set of keying material and the second set of keying material. A binding token is created by cryptographically signing at least the device identity authenticated in the first authentication and the subscriber identity authenticated in the second authentication using the set of compound keying material. The signed binding token is exchanged for verification with an authenticating and authorizing party.

摘要： The present invention discloses an apparatus and method for transferring digital content data. In one example, original digital content data stored on a first device in an encrypted state is transcoded (after being decrypted) to create a modified version of the original digital content data. The modified version of the original digital content data is then encrypted with a new content key. The modified version and at least one content key generator are transferred to a second device, where the at least one content key generator is used to recreate the new content key for enabling (and decrypting) the modified version of the original digital content data at the second device. Notably, the original digital content data stored in the first device is disabled contemporaneously with the transfer of the modified version and the at least one content key generator to the second device. Afterwards, the disabled original digital content data is re-enabled on the first device, and disabled on the second device.

摘要： A method and system for generating an electronic key used in an electronic transaction can be created by executing a one-way function on a host that derives the electronic key from a key seed saved in a non-volatile storage unit of the host and a unique host identification that is resident on the host. The function is preferably executed each time an electronic transaction requiring the use of the electronic key is made.
