Abstract: A system and method for securing data to be protected of a piece of equipment are provided. The equipment comprises: a space; at least one device for processing the data; a safety module comprising at least one controller connected to at least one memory for sensitive data, the sensitive data giving access to the data; and at least one supervision sensor. The method comprises: transmitting at least one signature through the sensor(s), to the safety module, the signature being based on a signal received by the respective sensor and giving information on the physical condition of the space; comparing in the safety module at least one of the signatures and/or a value inferred from at least one of the signatures with at least one reference value and/or at least one reference signature; limiting access to the data being based on the comparison of at least one of the signatures.

Abstract: The present invention relates to a device for detecting the opening of a hatch closing a case in an item of equipment including one or more electronic circuit boards, the planes of which are substantially orthogonal to the plane formed by the said hatch, at least one of the said boards including at least two conductive parts electrically insulated from one another and each connected to a detection circuit, a conductive element being attached to the inner side of the hatch, a portion of each of the conductive parts extending laterally to the side of the edge of the said electronic circuit board which is proximal to the hatch, the said conductive element being placed facing the said conductive parts so as to come into contact with them when the hatch is placed in the closed position.

Abstract: The method is applicable to the reception of data in the case of a digital transmission in which the pieces of data are transmitted by a unit of equipment A to a unit of equipment B with an accompanying clock signal HA. This accompanying clock signal transmitted by the transmitter equipment A is used by the receiver equipment B to sample the transmitted data. An alternation is effected at the receiver equipment B between a phase of operation during which the clock signal HA accompanying the data is replaced by a local clock signal HLS of the same frequency and a phase of operation during which the local clock signal is periodically re-synchronized with the accompanying clock signal. Means to implement the method are also disclosed.
