Abstract
A multimedia content processing device for processing multimedia contents implementing a plurality of virtual machines is provided. The device is able to receive encrypted multimedia content, protected by a content protection system, and provide the multimedia content in decrypted form to a user device, including an access controller authorizing the provision of the decrypted multimedia content to the user device, a first securer for executing security services having a first associated level of security and a second securer for executing services having an associated level of security lower than the first level of security. The device includes a hypervisor able to control the execution of at least three groups of virtual machines, the groups of virtual machines being executed in a strictly separate manner, including, the first two groups being dedicated to executing services with a level of security lower than the first level of security and the third group of virtual machines able to implement security services with a first level of security and to act as trusted third parties for services of the first and second groups of virtual machines.
