Method and device for controlling access to out-of-band contents for combination with trusted contents, and associated equipments

摘要

A method is intended for controlling access to out-of-band contents, provided by an out-of-band source (N1), by at least one communication equipment (CE) connected to a managed source (N2), providing trusted contents, and coupled to this out-of-band source (N1). This method comprises the steps of:(i) transmitting security data, representative of a policy defining out-of-band contents that are allowed to be combined with a trusted content, from a communication equipment (CE) to a network equipment (NE) connected to the out-of-band source (N1), and(ii) transmitting a message, requesting transmission on a chosen trusted communication path (TP) of a chosen out-of-band content to be combined with the trusted content, from the communication equipment (CE) to the network equipment (NE), then enforcing the policy associated to this trusted content into a security means (SM) of the network equipment (NE), then transmitting this chosen out-of-band content to at least the communication equipment (CE) requesting it through this chosen trusted communication path (TP) if it conforms to the enforced policy.
