摘要： A method and system of binding content at first access is disclosed. A nonvolatile storage device may provide a content access script and a content binding script in order to access protected content. An accessing application may attempt to access the protected content by executing a content access script. The accessing application must have permission to access and execute the content access script. If the accessing application cannot access or execute the content access script, the accessing application may access and execute the content binding script. The content binding script contains instructions that enable the accessing application to successfully execute the content access script. The content binding script, when executed, may disable itself from being executed again by moving critical information associated with the access to protected data. Thus, the content binding script may be executed once to enable an accessing application to successfully execute the content access script.
摘要翻译：公开了一种在第一次访问时绑定内容的方法和系统。非易失性存储设备可以提供内容访问脚本和内容绑定脚本，以访问受保护的内容。访问应用可以通过执行内容访问脚本来尝试访问受保护的内容。访问应用程序必须具有访问和执行内容访问脚本的权限。如果访问应用程序无法访问或执行内容访问脚本，访问应用程序可以访问和执行内容绑定脚本。内容绑定脚本包含允许访问应用程序成功执行内容访问脚本的指令。内容绑定脚本在执行时可能会通过移动与受保护数据的访问相关联的关键信息来禁止其再次执行。因此，可以执行内容绑定脚本一次以使访问应用能够成功地执行内容访问脚本。

摘要： A method for accessing content is provided. In this method, a first parameter associated with a license is retrieved. The license is associated with the content. A second parameter associated with the content also is retrieved. With the first and second parameters, a third parameter based on the first and second parameters is generated. The third parameter is configured for use in decrypting the content and the content can be accessed based on the third parameter. An apparatus is also provided comprising a memory and a processor in communication with the memory. The processor is configured to retrieve a first parameter associated with a license; retrieve a second parameter associated with the encrypted content; generate a third parameter based on the first and second parameters; and access the encrypted content based on the third parameter.
摘要翻译：提供了一种用于访问内容的方法。在该方法中，检索与许可证相关联的第一参数。许可证与内容相关联。与内容相关的第二个参数也被检索。利用第一和第二参数，生成基于第一和第二参数的第三参数。第三参数被配置用于解密内容，并且内容可以基于第三参数被访问。还提供了一种设备，其包括存储器和与存储器通信的处理器。处理器被配置为检索与许可证相关联的第一参数; 检索与加密内容相关联的第二参数; 基于第一和第二参数生成第三参数; 并根据第三个参数访问加密的内容。

摘要： A method for accessing content stored on a memory device is provided. In this method, a request to access the content is transmitted and a session ticket is received. The session ticket includes a parameter used to decrypt the content and the session ticket is generated based on a variable that is configured to change at a session. The content may be accessed based on the session ticket. An apparatus is also provided comprising a memory and a processor in communication with the memory. The processor is configured to: transmit a request to a memory device to access content stored in the memory device; receive a session ticket; and access the content based on the session ticket. The session ticket includes a parameter used to decrypt the content and the session ticket is generated based on a number that is configured to change at a session.

摘要： One or more rights objects (RO) files may be used for storing RO's preferably in the protected area available only to authenticated users. A RO navigation file is stored preferably in an unprotected public area containing status bits, where each status bit identifies whether a location in a RO file contains a valid RO or not. Preferably, there is a one-to-one correspondence between the location for a RO in a RO file and a location in the RO navigation file for the status bit which identifies whether its corresponding location in the RO file contains a valid RO or not. Whether a particular location in a RO file contains a valid RO or not can be found by checking its corresponding status bit in the RO navigation file. By finding out whether a particular location in a RO file contains a valid RO or not in this manner, it is possible to delete ROs without having to go through an authentication process. The process of finding an empty slot in the RO file for storing a new RO is also simplified. This greatly increases the efficiency of RO management. A similar system may be used for management of content encryption/ encryption keys for protecting content files.
摘要翻译：一个或多个权利对象（RO）文件可以用于优选地存储在仅可用于认证用户的保护区域中的RO。 RO导航文件优选存储在包含状态位的未受保护的公共区域中，其中每个状态位标识RO文件中的位置是否包含有效的RO。优选地，在RO文件中的RO的位置与用于状态位的RO导航文件中的位置之间存在一对一的对应关系，该状态位识别其在RO文件中的对应位置是否包含有效的RO。通过检查RO导航文件中的相应状态位，可以找到RO文件中的特定位置是否包含有效的RO。通过以这种方式找出RO文件中的特定位置是否包含有效的RO，可以删除RO而无需经过认证过程。在RO文件中寻找用于存储新的RO的空闲时隙的处理也被简化。这大大提高了RO管理的效率。类似的系统可用于管理内容加密/加密密钥以保护内容文件。

摘要： A host connected to two or more memory cards includes an interface manager that assigns card identifiers to memory cards according to the types of memory cards present. The interface manager also assigns volume identifiers to partitions within memory cards. Applications use a pathname that includes a card identifier and a volume identifier to access a partition and files.
