    Abstract: Encryption logic to identify a particular session key, where the particular session key is one of a plurality of session keys for use in encrypting content to be sent from a first device. The encryption logic is to encrypt particular content with the particular session key to obtain encrypted particular content. I/O logic is provided that can cause the particular content to be sent with a key refresh structure, where the key refresh structure is to identify that the particular session key was used to encrypt the particular content.

    Abstract translation: 用于识别特定会话密钥的加密逻辑,其中特定会话密钥是用于加密要从第一设备发送的内容的多个会话密钥之一。 加密逻辑是用特定会话密钥加密特定内容以获得加密的特定内容。 提供I / O逻辑,其可以使得特定内容以密钥刷新结构发送,其中密钥刷新结构用于标识特定会话密钥用于加密特定内容。

    Abstract: This disclosure is directed to content protection key management. In general, devices may include secure processing resources configured to derive content keys (e.g., for use in decrypting secure content) using key ladders. In one embodiment, a device may comprise, for example, at least a secure processing module to derive content keys for use in decrypting secure content. The secure processing module may include, for example, a key ladder storage module and a secure key storage module. The key ladder storage module may be to store at least one key ladder for use in deriving at least one content key. The secure key storage module may be to store the at least one content key derived using the key ladder.

    Abstract translation: 本公开涉及内容保护密钥管理。 通常,设备可以包括被配置为使用密钥梯子导出内容密钥(例如,用于解密安全内容)的安全处理资源。 在一个实施例中,设备可以包括例如至少一个安全处理模块,以导出用于解密安全内容的内容密钥。 安全处理模块可以包括例如密钥梯形图存储模块和安全密钥存储模块。 关键梯形图存储模块可以存储用于导出至少一个内容密钥的至少一个键梯。 安全密钥存储模块可以存储使用密钥梯子导出的至少一个内容密钥。
