A device protects an incoming multimedia signal with a protection that is controllable and configured for enabling or disabling an application for an interface protection on an outgoing signal coming from the incoming signal. An output interface is configured for delivering the outgoing signal on an output. An authorization process is performed for authorizing or otherwise a control over the enabling or disabling of the interface protection application depending on security rules.

Method and device for improving the protection of a multimedia signal against a malicious attack

A signal is protected against an attack by an enhancement process that checks the conformity of an actual state of the signal with respect to an expected state. A protective action is exercised on the signal if the actual state of the signal is not in conformity with the expected state, so as to neutralize or nullify said attack.
