摘要： A trusted component on a device includes a secure HWID therein and is verified by obtaining a key from the device, and verifying each signed component of the operating system of the device therewith. A driver table is examined to locate a HWID driver which is verified as containing a pointer back to an address inside a kernel. The verified operating system is called to obtain the secure HWID from a HWID component by way of the HWID driver and to return same to the trusted component. Thereafter, the returned HWID is verified as matching the HWID included with the trusted component.

摘要： A key management interface that allows for different key protection schemes to be plugged into a digital rights management system is disclosed. The interface exposes the functionality of signing data, decrypting data encrypted using a public key, and re-encrypting data encrypted using the public key exported by the interface to a different authenticated principal (i.e., a different public key). Thus, a secure interface can be provided such that the data does not enter or leave the interface in the clear. Such an interface exports private key operations of signing and decryption, and provides security and authentication for the digital asset server in licensing and publishing. During publishing, a client can encrypt asset keys such that only a specified entity can decrypt it, using a plug-in, for example, that implements the aforementioned interface. During licensing, the license issuing entity can use the interface to decrypt keys for assets and to sign licenses and rights labels such that the asset is protected and consumable by a host digital rights management platform. The interface thus provides an abstraction for key operations.
摘要翻译：公开了一种允许将不同密钥保护方案插入数字版权管理系统的密钥管理接口。该接口公开了签名数据的功能，解密使用公共密钥加密的数据，并且使用由该接口导出的公共密钥加密的数据重新加密到不同的认证主体（即不同的公钥）。因此，可以提供安全接口，使得数据不会进入或离开界面清楚。这样的接口导出签名和解密的私钥操作，并为许可和发布中的数字资产服务器提供安全和身份验证。在发布期间，客户端可以加密资产密钥，使得只有指定的实体可以使用例如实现上述接口的插件来对其进行解密。在许可期间，许可证发放实体可以使用接口解密资产的密钥，并签署许可证和权利标签，以使资产受到主机数字版权管理平台的保护和消耗。因此，该接口为关键操作提供了一个抽象。

摘要： A secure repository individualized for a hardware environment and a method and system for providing the same. The secure repository includes a hidden cryptographic key and code that applies the key without requiring access to a copy of the key. The code that implements the secure repository is generated in a manner that is at least partly based on a hardware ID associated with the hardware environment in which the secure repository is to be installed, and may also be based on a random number. Cryptographic functions implemented by the secure repository include decryption of encrypted information and validation of cryptographically signed information. The secure repository may be coupled to an application program, which uses cryptographic services provided by the secure repository, by way of a decoupling interface that provides a common communication and authentication interface for diverse types of secure repositories. The decoupling interface may take the form of a single application programmer interface (API) usable with multiple dynamically linkable libraries.

摘要： A license is issued to a user as decryption and authorization portions. The decryption portion is accessible only by such user and has a decryption key (KD) for decrypting corresponding encrypted digital content and validating information including an identification of a root trust authority. The authorization portion sets forth rights granted in connection with the digital content and conditions that must be satisfied to exercise the rights granted, and has a digital signature that is validated according to the identified root trust authority in the decryption portion. The user issued accesses the decryption portion and employs the validation information therein to validate the digital signature of the authorization portion. If the conditions in the authorization portion so allow, the rights in the authorization portion are exercised by decrypting the encrypted content with the decryption key (KD) from the decryption portion and rendering the decrypted content.

摘要： A digital rights management system for the distribution, protection and use of electronic content. The system includes a client architecture which receives content, where the content is preferably protected by encryption and may include a license and individualization features. Content is protected at several levels, including: no protection; source-sealed; individually-sealed (or “inscribed”); source-signed; and fully-individualized (or “owner exclusive”). The client also includes and/or receives components which permit the access and protection of the encrypted content, as well as components that allow content to be provided to the client in a form that is individualized for the client. In some cases, access to the content will be governed by a rights construct defined in the license bound to the content. The client components include an object which accesses encrypted content, an object that parses the license and enforces the rights in the license, an object which obtains protection software and data that is individualized for the client and/or the persona operating the client, and a script of instructions that provides individualization information to a distributor of content so that the content may be individualized for the client and/or its operating persona. Content is generally protected by encrypting it with a key and then sealing the key into the content in a way that binds it to the meta-data associated with the content. In some instances, the key may also be encrypted in such a way as to be accessible only by the use of individualized protection software installed on the client; thereby binding use of the content to a particular client or set of clients.
摘要翻译：数字版权管理系统，用于分发，保护和使用电子内容。该系统包括接收内容的客户端架构，其中优选地通过加密保护内容，并且可以包括许可证和个性化特征。内容受到多个级别的保护，包括：无保护; 源密封; 单独密封（或“铭刻”）; 源代码; 和完全个性化（或“所有者独占”）。客户端还包括和/或接收允许加密内容的访问和保护的组件以及允许以为客户端个性化的形式向客户端提供内容的组件。在某些情况下，访问内容将受到绑定到内容的许可证中定义的权利结构的约束。客户端组件包括访问加密内容的对象，解析许可证并执行许可证中的权限的对象，获得保护软件的对象和为客户端和/或操作客户端的个人化的数据，以及向内容分发者提供个性化信息的指令脚本，使得可以为客户端和/或其操作人员个性化内容。内容通常通过用密钥加密来保护，然后以将其绑定到与内容相关联的元数据的方式将密钥密封到内容中。在某些情况下，密钥还可以以仅通过使用安装在客户机上的个性化保护软件可访问的方式进行加密; 从而将内容的使用绑定到特定的客户端或一组客户端。

摘要： A Digital Rights Management (DRM) system has a plurality of DRM servers performing DRM functionality and an entering DRM-E server is enrolled into the system by an enrolling DRM-R server such that the entering DRM-E server is to be trusted within the system. The DRM-E server sends an enrollment request to the DRM-R server including a proffering identification and a public key (PU-E). The DRM-R server validates the proffering identification, and, if the request is to be honored, generates a digital enrollment certificate with (PU-E) for the DRM-E server to enroll such DRM-E server into the DRM system. The now-enrolled DRM-E server with the generated enrollment certificate is able to employ same to issue DRM documents within the DRM system.
