Security architectures improved in two and three parts that are physically separated

摘要

Even in the device comprising at least one red zone (1), a black (2), a management area (3), a resource cryptographic (4), comprising at least the following elements: a host range (5) comprising the red zone (1), the black region (2) and the management area (3) separated logically, the cryptographic resource (4) communicating with the elements of the host range (5) by means of the interfaces follows: an interface red (10) for the pharmaceutical emitted towards the red zone, an interface black (11) for the data transmitted to the black region, an interface management (12) for the data transmitted to the management area, the three interfaces (10, 11, 12) being physically separated, the cryptographic field being separated physically from the host range.
