Claim:
A system for processing data, the system comprising: at least two domains having different security levels, the data being able to be exchanged between at least a first domain having a security level A and a second domain having a security level B, A being different from B a plurality of elementary entities, each elementary entity including a routing module and a processing device, the routing module including a first input in the domain having the A security level for receiving data to be processed, a first output into the domain having the A security level for outputting data that has not been processed and that remains in the domain with the A security level, and a second output for outputting data to the processing device to be processed by the processing device and transferred into the domain with the B security level via an output of the processing device, wherein each of the plurality of elementary entities is communicatively connected to another elementary entity only through the respective routing module, and wherein for each elementary entity, the processing device in that elementary entity is communicatively connected to the domain having the security level A only through the second output of the corresponding routing module for that elementary entity.
