摘要： 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.

摘要： A method, device, and system for establishing a secure communication session with a server includes initiating a request for a secure communication session, such as a Secure Sockets Layer (SLL) communication session with a server using a nonce value generated in a security engine of a system-on-a-chip (SOC) of a client device. Additionally, a cryptographic key exchange is performed between the client and the server to generate a symmetric session key, which is stored in a secure storage of the security engine. The cryptographic key exchange may be, for example, a Rivest-Shamir-Adleman (RSA) key exchange or a Diffie-Hellman key exchange. Private keys and other data generated during the cryptographic key exchange may be generated and/or stored in the security engine.

摘要： 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.
摘要翻译：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。

摘要： In one embodiment, a method for sensory verification comprises exchanging at least one data item with a computing unit and selecting a sequence number. Such selection may be accomplished by generation of the sequence number or manual entry by the user. Thereafter, a transformation is periodically performed on the data item, the sequence number and optionally a random value to produce a sequence of values, each value being used to produce a perceivable sensory element for comparison with another sensory element produced by another computing unit.
