摘要： A software version control system manages versioned applications in a client-server computing system environment. Thereby this is a management system for computer application (software) distribution where a number of client devices coupled to a server may be executing different versions of a particular computing application. The system manages updates to the applications and enforces rules or policies to use the most recent version whenever possible.

摘要： Disclosed herein are systems, computer-implemented methods, and computer-readable storage media for call path enforcement. The method includes tracking, during run-time, a run-time call order for a series of function calls in a software program, and when executing a protected function call during run-time, allowing or causing proper execution of a protected function call only if the run-time call order matches a predetermined order. The predetermined order can be an expected run-time call order based on a programmed order of function calls in the software program. The method can include maintaining an evolving value associated with the run-time call order and calling the protected function by passing the evolving value and function parameters corrupted based on the evolving value. The protected function uncorrupts the corrupted parameters based on the passed evolving value and an expected predetermined call order. A buffer containing the uncorrupted parameters can replace the corrupted parameters.
摘要翻译：本文公开了用于呼叫路径实施的系统，计算机实现的方法和计算机可读存储介质。该方法包括在运行期间跟踪软件程序中一系列函数调用的运行时调用顺序，以及在运行时执行受保护函数调用时，只允许或导致仅受保护函数调用的正确执行如果运行时间调用顺序与预定顺序相匹配。预定顺序可以是基于软件程序中的功能调用的编程顺序的期望的运行时呼叫顺序。该方法可以包括维护与运行时呼叫顺序相关联的演进值，并通过传递基于演进值而破坏的演进值和功能参数来调用受保护功能。受保护的功能基于传递的演进值和预期的预定呼叫顺序来破坏已损坏的参数。包含未受损参数的缓冲区可以替换损坏的参数。

摘要： In the context of a computer client-server architecture, typically used in the Internet for communicating between a server and applications running on user computers (clients), a method is provided for enhancing security in the context of digital rights management (DRM) where the server is an untrusted server that may not be secure, but the client is secure. This method operates to authenticate the server to the client and vice versa to defeat hacking attacks intended to obtain confidential information. Values passed between the server and the client include encrypted random numbers, authentication values and other verification data generated using cryptographic techniques including double encryption.

摘要： Methods, media and systems that use an encoded opaque pointer in an API between a client process and a library process. An encoded opaque pointer, in one embodiment, can be received by the library process from the client process, and the library process can decode the opaque pointer to obtain an address in memory containing a data structure pointed to by the opaque pointer. The library process can operate on the data structure to create a revised or processed data structure, stored in the same or different address in heap memory or stack memory, and the library process can encode and return a new opaque pointer, for the processed data structure, to the client process.

摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for key space division and sub-key derivation for mixed media digital rights management content and secure digital asset distribution. A system practicing the exemplary method derives a set of family keys from a master key associated with an encrypted media asset using a one-way function, wherein each family key is uniquely associated with a respective client platform type, wherein the master key is received from a server account database, and identifies a client platform type for a client device and a corresponding family key from the set of family keys. The system encrypts an encrypted media asset with the corresponding family key to yield a platform-specific encrypted media asset, and transmits the platform-specific encrypted media asset to the client device. Thus, different client devices receive device-specific encrypted assets which can be all derived based on the same master key.

摘要： Some embodiments provide an account-based DRM system for distributing content. The system includes several devices that are associated with an account and a set of DRM computers that receives a request to access a piece of content on the devices associated with the 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 piece of content on the particular device. In some 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.

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 a method for determining whether a subscription for using digital content on a user device has elapsed. The method compares a first collision free image of a first set of entities in the user device with a second collision free image for a second set of entities in the user device at a second instance in time. Based on the comparison, the method determines whether the subscription has elapsed.
