    Abstract: Certains modes de réalisation de l'invention mettent à disposition un procédé de gestion numérique des droits (DRM) destiné à distribuer un contenu à des utilisateurs (1) sur un réseau (120). Sur la base d'un premier ensemble d'indices de diversité, le procédé identifie un premier élément de sécurité (SE) destiné à distribuer un ensemble de contenu à un premier ordinateur (115). L'ensemble de contenu comporte un ou plusieurs éléments de contenu. Sur la base d'un second ensemble d'indices de diversité, le procédé identifie un second élément de sécurité (SE) destiné à distribuer l'ensemble de contenu à un second ordinateur (115). Sur la base du premier élément de sécurité (SE), le procédé protège l'ensemble de contenu pour le premier ordinateur (115) et envoie l'ensemble de contenu protégé au premier ordinateur (115) au travers du réseau (120). Sur la base du second élément de sécurité (SE), le procédé protège l'ensemble de contenu pour le second ordinateur (115) et envoie l'ensemble de contenu protégé au second ordinateur (115) au travers du réseau (120) .

    Abstract: 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.

    Abstract: aparelho e método para processo de cifragem de bloco para ambientes inseguros. a presente invenção refere-se a método e aparelho para aumentar segurança de um algoritmo criptográfico tal como quando decifrando, cifrando ou de uma assinatura digital usando um cifrador do tipo de bloco tal como aes implementado, por exemplo, em um modelo de "caixa branca" com a chave de cifragem conhecida ou desconhecida no tempo de compilação. este método é seguro para uso em ambientes de transmitir com confiança, particularmente para garantir chaves criptográficas. as tabelas de consulta características de tais algoritmos são aqui protegidas contra ataque ao fazer todas as tais tabelas do mesmo tamanho e indistinguíveis, e adicionalmente ao mascarar os valores de saída de tais tabelas, tipicamente onde a tabelas executam uma função de permutação ou uma operação or exclusiva lógica.

    IPC: G06F21/10

    Abstract: Disclosed herein are systems, methods, and media for preventing the unauthorized playback of content. A system receives, from a client device associated with a user profile, a download authorization start request for an asset for which the user profile is authorized. That system identifies a number of available slots for progressively downloading content. If the number of available slots is greater than zero, the system assigns an available slot from the number of available slots to the client device to yield an assigned slot. That system transmits security information, a download authorization key, and a download authorization duration associated with the assigned slot to the client device in response to the download authorization start request, wherein the security information and download authorization key allow the client device to start a progressive download of the asset for the download authorization duration. At the end of the download authorization, that system terminates the download authorization and releases the assigned slot.

    Abstract: 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.
