摘要： In the computer client-server context, typically used in the Internet for communicating between a central server and user computers (clients), a method is provided for token passing which enhances security for client-server communications. The token passing is opaque, that is tokens as generated by the client and server are different and can be generated only by one or the other but can be verified by the other. This approach allows the server to remain stateless, since all state information is maintained at the client side. This operates to authenticate the client to the server and vice versa to defeat hacking attacks, that is, penetrations intended to obtain confidential information. The token as passed includes encrypted values including encrypted random numbers generated separately by the client and server, and authentication values based on the random numbers and other verification data generated using cryptographic techniques.
摘要翻译：在计算机客户端 - 服务器上下文中，通常在因特网中用于在中央服务器和用户计算机（客户端）之间进行通信，提供了用于令牌传递的方法，其增强了客户机 - 服务器通信的安全性。令牌传递是不透明的，即客户端和服务器生成的令牌是不同的，只能由一个或另一个生成，但可以由另一个验证。这种方法允许服务器保持无状态，因为所有状态信息都保留在客户端。这样做可以将客户端验证到服务器，反之亦然，以打败黑客攻击，即用于获取机密信息的渗透。传递的令牌包括加密值，包括由客户端和服务器单独生成的加密随机数，以及基于使用加密技术生成的随机数和其他验证数据的认证值。

摘要： For digital rights management (DRM) of e.g. digitally delivered music or video, a technique to make the decryption keys more secure. The technique fragments a message (song or video or other) into a number of portions, and uses a different decryption key for each portion. Each of the various keys is a function of the preceding key, in one version. In another version, each key is a function of a seed value and of the particular portion of the material with which the key is associated.

摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for obfuscating data via a pseudo-random polymorphic tree. A server, using a seed value shared with a client device, generates a tag stream according to a byte-string algorithm. The server passes the tag stream and the data to be transmitted to the client device through a pseudo-random polymorphic tree serializer to generate a pseudo-random polymorphic tree, which the server transmits to the client device. The client device, using the same seed and byte-string algorithm, generates the same tag stream as on the server. The client passes that tag stream and the received pseudo-random polymorphic tree through a pseudo-random polymorphic tree parser to extract the data. Data to be transmitted from the server to the client device is hidden in a block of seemingly random data, which changes for different seed values. This approach obfuscates data and has low processing overhead.

摘要： Some embodiments of the invention provide a digital rights management (DRM) method for distributing content to users over a network. Based on a first set of diversity indicia, the method identifies a first security element for distributing a set of content to a first computer. The set of content includes one or more pieces of content. Based on a second set of diversity indicia, the method identifies a second security element for distributing the set of content to a second computer. Based on the first security element, method protects the set of content for the first computer and sends the protected set of content to the first computer through the network. Based on the second security element, the method protects the set of content for the second computer and sends the protected set of content to the second computer through the network.

摘要： Some embodiments of the invention provide a method for distributing content over a network. The method distributes a single media storage structure to a device (e.g., a computer, portable player, etc.) that connects to the network. The media storage structure includes first and second pieces of encrypted content. Based on whether the device is allowed to access the first piece of content, the second piece of content, or both, the method provides the device with a set of keys for decrypting the pieces of the content that the device is able to access. The provided set of keys might include one or more keys for decrypting only one of the two encrypted pieces of content. Alternatively, it might include one or more keys for decrypting both encrypted pieces of content. For instance, the selected set of keys might include a first key for decrypting the first encrypted piece and a second key for decrypting the second encrypted piece. Based on the provided set of keys, the device can then decrypt and access either one of the two pieces of content in the media storage structure or both pieces of encrypted content in the media storage structure.

摘要： Some embodiments provide an account-based DRM system for distributing content. The system includes several devices that are associated with one particular account. The system also includes a set of DRM computers that receives a request to access a particular piece of content on the devices associated with the particular account. The DRM computer set then generates a several keys for the devices, where each particular key of each particular device allows the particular device to access the particular piece of content on the particular device. Through a network, the DRM computer set of some embodiments sends the particular piece of content and the generated keys to the devices associated with the particular account. The network is a local area network, a wide area network, or a network of networks, such as the Internet. In some of these embodiments, the DRM computer set sends the content and keys to one device (e.g., a computer), which is used to distribute the content and the key(s) to the other devices associated with the account. In some embodiments, the DRM computer set individually encrypts each key in a format that is used during its transport to its associated device and during its use on this device.
