摘要： The present invention provides for trusted side-band communications between components in a computer system, so that use of the system bus may be avoided. Two components may be connected by means other than a bus (e.g., an infrared port, a wire, an unused pin, etc.), whereby these components may communicate without the use of the system bus. The non-bus communication channel may be referred to as “side-band.” The side-band channel may be used to communicate information that might identify the user's hardware (e.g., a public key) or other information that the user may not want to be easily intercepted by the public at large. Communication over the side-band channel may also be used to verify that the participants in a communication are within a defined positional relationship to each other.
摘要翻译：本发明提供计算机系统中的组件之间的可靠的边带通信，从而可以避免使用系统总线。两个组件可以通过除总线（例如，红外线端口，电线，未使用的引脚等）之外的方式连接，由此这些组件可以在不使用系统总线的情况下进行通信。非总线通信信道可以被称为“边带”。边带频道可以用于传达可能识别用户硬件（例如，公共密钥）的信息或用户可能不希望容易被公众容易地截获的其他信息。通过边带信道的通信也可以用于验证通信中的参与者在彼此之间的定义的位置关系内。

摘要： Digital content is released to a rendering application for forwarding by such rendering application to an ultimate destination by way of a path therebetween. The path is defined by at least one module, and the digital content is initially in an encrypted form. An authentication of at least a portion of the path is performed to determine whether each defining module thereof is to be trusted to appropriately handle the digital content passing therethrough. The encrypted digital content is decrypted if in fact each such defining module is to be trusted, and the decrypted digital content is forwarded to the rendering application for further forwarding to the ultimate destination by way of the authenticated path.

摘要： Theft of decompressed digital content as the content is being rendered is prevented. A requested slow-down of the rendering of the content is detected. Transfers of relatively large amounts of data are detected. A re-compressor-based requested slow-down of the rendering of the content is detected. A re-compressor re-compressing the content is detected. In each situation, the detected activity is presumably initiated by a content thief attempting to steal the content. In each situation, the detected activity is responded to in a manner designed to frustrate the presumed attempt of the content thief to steal the content.

摘要： An enforcement architecture and method for implementing digital rights management are disclosed. Digital content is distributed from a content server to a computing device of a user and received, and an attempt is made to render the digital content by way of a rendering application. The rendering application invokes a Digital Rights Management (DRM) system, and such DRM system determines whether a right to render the digital content in the manner sought exists based on any digital license stored in the computing device and corresponding to the digital content. If the right does not exist, a digital license that provides such right and that corresponds to the digital content is requested from a license server, and the license server issues the digital license to the DRM system. The computing device receives the issued digital license and stores the received digital license thereon.

摘要： A counter is provided which can be implemented in flash memory allowing longer life through fewer erasures. The counter is incremented using a method that minimizes bit transitions from 1 to 0. In one embodiment, the counter is implemented in m+n bits. The bits of the counter are grouped into a binary portion of the counter of m bits and a unary portion of the counter of n bits. In order to increment the counter, the unary portion of the counter is incremented first. When the unary portion of the counter reaches a specific value, the binary portion of the counter is incremented. This limits 1 to 0 bit transitions and allows a large range of unique values to be read from the counter. In another embodiment, two unary counters are formed, which dynamically change in size as the counter is incremented.

摘要： To establish trust between first and second entities, the first entity sends an attestation message to the second entity, including a code ID, relevant data, a digital signature based on the code ID and data, and a certificate chain. The second entity verifies the signature and decides whether to in fact enter into a trust-based relationship with the first entity based on the code ID and the data in the attestation message. Upon so deciding, the second entity sends a trust message to the first entity, including a secret to be shared between the first and second entities. The first entity obtains the shared secret in the trust message and employs the shared secret to exchange information with the second entity.
摘要翻译：为了在第一和第二实体之间建立信任，第一实体向第二实体发送认证消息，包括代码ID，相关数据，基于代码ID和数据的数字签名以及证书链。第二实体验证签名，并且基于代码ID和认证消息中的数据来确定是否实际上与第一实体进行基于信任的关系。在这样确定的情况下，第二实体向第一实体发送信任消息，包括要在第一和第二实体之间共享的秘密。第一实体获取信任消息中的共享密钥，并使用共享密钥与第二实体交换信息。
