摘要： A license data structure and distribution (issuance) method are provided, that can accommodate one domain including multiple content playback devices and/or users. A method for creating license data in the invention includes the steps of: creating raw license data to be issued; firstly encrypting the raw license data with an encryption key of a user and/or device; and encrypting the data encrypted with the user and/or device public key using a public key of a home domain. Also, a license data structure of the invention includes an encrypted license block created by firstly encrypting raw license data containing data for playing content with a distributed encryption key of a user and/or device, and then secondly encrypting this with a distributed encryption key of a home domain; and TAG information necessary for decryption of a second encryption capsule.

摘要： Provided are domain contexts indicating user and device based domain systems for being applied to a new digital content protection/management system, and management methods thereof. A concept of “domain” is introduced in the present invention so that various business models can be obtained in accordance with content use of one home or small-sized group. The domain refers to as a group of user and device SAV and PAV indicating a context for being applied to the domain system includes: a domain identifier for specifying a domain as a region containing at least one content execution device and at least one content user; domain authentication information for guaranteeing authenticity of the domain; a user list containing information of users belonging to the domain; and a device list containing devices belonging to the domain.

摘要： A tool pack structure includes: a signature value for guaranteeing authenticity of a tool pack; a tool pack identifier for identifying the tool pack; each unit tool pack provided according to a hardware platform; and tool pack data containing initial values assigned when each unit tool pack is used. Each tool pack includes platform information indicating information about hardware in which the tool pack may be used; a tool agent that is a program activated for content execution; and a tool group including at least one tool program activated by the tool pack agent for processing content according to a predetermined rule. A tool agent leaves operation of a protection tool group used by a specific service provider entirely to a tool agent (execution code) provided together with the tool group by service providers. Accordingly, information about the used tools does not have to be disclosed to the public. Since a user terminal simply calls each tool agent, it can support interoperability with other DRM techniques.
摘要翻译：工具包结构包括：用于保证工具包的真实性的签名值; 用于识别工具包的工具包标识符; 每个单元工具包根据硬件平台提供; 和包含使用每个单位工具包时分配的初始值的工具包数据。每个工具包包括指示可以使用工具包的硬件的信息的平台信息; 作为激活用于内容执行的程序的工具代理; 以及包括由工具包代理激活的至少一个工具程序的工具组，用于根据预定规则处理内容。工具代理将特定服务提供商使用的保护工具组完全转移给服务提供商与工具组一起提供的工具代理（执行代码）。因此，关于使用的工具的信息不必向公众公开。由于用户终端简单地调用每个工具代理，它可以支持与其他DRM技术的互操作性。
