Abstract: In order to distribute content made available by an entity of origin, a first distribution entity receives a request to access the content by a client entity. If this is a first access request received by the first distribution entity for the content, the distribution entity acts as a proxy: it receives, from the entity of origin or from a second distribution entity, and retransmits to the client entity, a response including the content, and it stores the content in a cache. In addition, it transmits, to the entity of origin or to the second distribution entity, a context request, receives in return a response including a description of the execution context of the access request, and stores the description. Otherwise, the first distribution entity uses the previously stored description in order to perform an execution of the later access request.

Abstract: A method for distributing a piece of content in a content distribution network, provided by a source entity of which the integrity is ensured by means of a private key, the method comprising the following steps implemented by a content distribution entity: —receiving a request to access the piece of content from a user device; —sending, to a proxy entity, a request to have at least one piece of data signed by means of the private key; —receiving the at least one piece of signed data, the at least one piece of signed data certifying the integrity of said distribution entity for the user device; —sending a public key associated with the private key to the user device; —sending the at least one piece of signed data to the user device and distributing the content to the user device.
