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.

摘要： Disclosed herein are systems, methods and computer readable media for performing authentication. The proposed scheme utilizes new algorithms that introduce randomness using a physical value for authentication. An exemplary method includes sharing an initial state value S(0) with a sender and a receiver, generating a sender S(t, v) based on a parameter t and an identifier v and based at least in part on the value S(0). The method includes generating a receiver S(t, v) from S(0) based on the parameter t and the identifier v wherein the parameter t is related to a physical value in authenticating the identifier v based on a comparison of the sender S(t, v) and the receiver S(t, v). The process of generating the sender S(t, v) and the receiver S(t, v) includes a random variable generated by a process such as by a random number generator, the Brownian Motion or Wiener Process. Other embodiments do not use the physical value for authentication.

摘要： Some embodiments of the invention provide a method of verifying the integrity of digital content. At a source of the digital content, the method generates a signature for the digital content by applying a hashing function to a particular portion of the digital content, where the particular portion is less than the entire digital content. The method supplies the signature and the digital content to a device. At the device, the method applies the hashing function to the particular portion of the digital content in order to verify the supplied signature, and thereby verifies the integrity of the supplied digital content.

摘要： Disclosed herein are systems, method and computer readable medium for providing authentication of an entity B by an entity A. In the method, entity A selects a value p, a range [a, b] and a granularity epsilon. Entity A sends p, [a, b], and epsilon to entity B. Entity B initializes a value yB=0 and for each x in {a, a+epsilon, . . . , b−epsilon, b} and computes z=E(x)*x. The function E(x) is an encryption scheme and the multiplication is carried out mod p. Entity B updates yB=yB+z. After processing each x, entity B sends yB to entity A. Entity A performs the same calculation and generates a yA value and compares yA with yB. If yB=yA, Entity A authenticate entity B. In one aspect, a light HMAC scheme splits an input x into n blocks with key expansion.
