摘要： Disclosed herein are systems, methods, and non-transitory computer-readable media for enforcing application usage policies. As part of an application purchase transaction, the application distributor creates a unique proof of purchase receipt. This receipt can be bundled with the application and delivered to the purchaser. Each machine can maintain an authorization file that lists the users authorized to use applications on that machine. A system configured to practice the method verifies that a user is authorized to use an application on a machine based on an application proof of purchase receipt and the authorization file. If the application proof of purchase receipt and the authorization file are both valid, the system checks if the user account identifier in the receipt is contained in the authorization file. If so, the user can be considered authorized to use the application on the machine.

摘要： In the field of computer enabled cryptography, such as a keyed block cipher having a plurality of rounds, the cipher is hardened against an attack by a protection process which obscures the round keys using the properties of group field automorphisms and applying masks to the states of the cipher, for encryption or decryption. This is especially advantageous in a "White Box" environment where an attacker has full access to the cipher algorithm, including the algorithm's internal state during its execution. This method and the associated computing apparatus are useful for protection against known attacks on "White Box" ciphers, by eliminating S-box operations, together with improved masking techniques and increasing the cipher's complexity against reverse engineering and key storage attacks.
摘要翻译：在计算机启用的密码学领域，例如具有多个回合的密钥分组密码，密码被抵御使用群组域自动生成的属性遮蔽轮密钥的保护过程而被强化，并将掩码应用于密码，用于加密或解密。这在“白盒”环境中特别有利，攻击者可以完全访问密码算法，包括算法的执行过程中的内部状态。该方法和相关联的计算装置对于通过消除S盒操作以及改进的掩蔽技术并增加密码的复杂度以逆向工程和密钥存储攻击来防止已知的对“白盒”密码的攻击是有用的。

摘要： Aspects relate to systems and methods implementing a scheme allowing a Verifier (V) to authenticate a Prover (P). The scheme comprises pre-sharing between V and P a graph of nodes. Each node is associated with a polynomial. V sends P data comprising data for selecting a polynomial of the graph, such as traversal data for proceeding from a known node to another node, a time interval, and a number k. P uses the time interval in an evaluation of the polynomial. P then uses the evaluation as a λ in a Poisson distribution, and determines a value related to a probability that a number of occurrences of an event equals k. P sends the determined value to V. V performs a similar determination to arrive at a comparison value. P authenticates V if the separately determined values match, or otherwise meet expectations. The process can be repeated to increase confidence in authentication.

摘要： Method and apparatus enabled by computer (or equivalent) hardware and software for protection of content downloaded or streamed over a computer network. The content is provided to the user via streaming or downloads in encrypted form. The encryption is such that the content key decryption information is transmitted so that it itself is encrypted to be both device and session unique; the key information can be used only to extract the content decryption key for a particular session and for a particular client device, preventing any further use or copying of the content other than in that session and for that particular client. The specificity is accomplished by using a device unique identifier and session-specific anti-replay information to encrypt the content key. A typical application is Internet streaming of audio or video to consumers.

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： 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： A method and associated apparatus for use in a data distribution process to allow an untrusted intermediary to re-encrypt data for transmission from an originator to a message receiver without revealing the data (message) or the cipher to the intermediary. This method uses a composition of two ciphers for re-encrypting the message at the intermediary, without revealing the plain text message or either cipher to the intermediary.

摘要： A video on demand system in the context of the Internet, for video rentals. A user accesses an on-line store to rent a video program or movie. The rental is for a limited time (such as 30 days) and within that thirty days, the video program or movie can only be viewed for a 24 hour time window. The time limits are enforced by the on-line store which maintains a database of each rental transaction and allows supply of the needed keys for decrypting the (encrypted) video or movie only if within the time limits.
