A device for the treatment of clinical high safe has two operating states.

摘要

The invention relates to a data processing device comprising a user unit (UUS) for the acquisition (CL) and/or the visual display (VS) of data; and a main unit for processing (UTP) data according to a predetermined processing algorithm (AT). According to the invention, the device further comprises an auxiliary, high-security processing unit (UTA), connected in order to carry out all of the data exchanges between the user unit (UUS) and the main processing unit (UTP). The auxiliary processing unit (UTA) comprises means for making data secure (MC); means of data transfer (B2) having a normal state, and a security state in which at least the data transferred in one direction are made secure, the processing algorithm (AT) of the main unit (UTP) determining the operational state of these means of data transfer (B2); means (MA) suitable for monitoring the authenticity of the said processing algorithm (AT) and acting autonomously; and means (MI) suitable for totally inhibiting the means of data transfer (B2) in the case where authenticity is not confirmed by the said monitoring.
