摘要： An apparatus may include circuitry, a cryptographic module, and a key store. The circuitry may hold a private key associated with first media information. The cryptographic module may operate on the private key to generate a number of first control keys for decrypting the first media information. The key store may hold the number of first control keys from the cryptographic module. In some implementations, the key store may include sufficient storage to store more than one control key from each of a number of different crypto modules. In some implementations, the key store may receive multiple control keys simultaneously or nearly so. In some implementations, the key store may output multiple control keys simultaneously, or nearly so, for decrypting multiple streams of media information at the same time.
摘要翻译：设备可以包括电路，加密模块和密钥存储。电路可以保持与第一媒体信息相关联的私钥。加密模块可以在私钥上操作以生成用于解密第一媒体信息的多个第一控制密钥。密钥存储器可以保存来自加密模块的第一控制密钥的数量。在一些实现中，密钥存储器可以包括足够的存储以从多个不同的密码模块中的每一个存储多于一个的控制密钥。在一些实现中，密钥存储器可以同时或接近接收多个控制键。在一些实现中，密钥存储可以同时或几乎同时地输出多个控制密钥，以同时解密多个媒体信息流。

摘要： An apparatus may include circuitry to permanently and inaccessibly store a first private key that is a shared secret between a manufacturer of the circuitry and a first vendor of first encrypted media information. It may also include a key ladder to provide plural layers of encryption to the first private key to generate a first result for decrypting the first encrypted media information. A cryptographic module may encrypt the first private key to generate a second result for a security purpose other than decrypting media information. The module also may include a key ladder, and the apparatus may include other key ladders using the private key.

摘要： Apparatus, systems, methods, and articles herein interact with an operating system in a network client to simulate an “always connected” network connection model. Upon activation, a network driver implementing embodiments herein indicates to the operating system that a network connection has been established, whether or not an actual connection is established. Some embodiments may also present a pseudo network address (e.g., an IP address) to the operating system in the case of a virtual network connection. Upon sensing an actual physical network connection, embodiments herein may handshake with the operating system to establish a real network connection, including communicating a network-assigned network address to the operating system. The operating system may in turn report (or continue to report) an active connection to application programs so that a user need not repeatedly re-activate the network connection manually. Other embodiments are described and claimed.
摘要翻译：本文中的装置，系统，方法和文章与网络客户端中的操作系统进行交互以模拟“始终连接”的网络连接模型。在激活时，实现本文实施方式的网络驱动程序向操作系统指示已经建立了网络连接，而不管实际连接是否建立。在虚拟网络连接的情况下，一些实施例还可以向操作系统呈现伪网络地址（例如，IP地址）。在感测到实际物理网络连接时，本文中的实施例可以与操作系统握手建立真实网络连接，包括将网络分配的网络地址传送到操作系统。操作系统可以依次报告（或继续报告）到应用程序的活动连接，使得用户不需要手动地重复地重新激活网络连接。描述和要求保护其他实施例。
