Method for operating a primary unit
First Claim
1. A method for operating a primary unit, the primary unit exchanging pieces of information with a secondary unit, the method comprising:
- receiving first pieces of information from the secondary unit, the first pieces of information being formed as a function of at least one first measured value of a physical variable in an area of the secondary unit and as a function of a first random number;
measuring the at least one physical variable in an area of the primary unit to obtain a second measured value;
ascertaining a first estimated value for the first random number as a function of the first pieces of information and of the second measured value;
measuring the at least one physical variable in the area of the primary unit to obtain a third measured value;
forming second pieces of information as a function of the first estimated value and of the third measured value; and
transmitting the second pieces of information to the secondary unit.

Abstract
A method for operating a primary unit which exchanges pieces of information with a secondary unit, including receiving first pieces of information from the secondary unit, the first pieces of information formed as a function of at least one first measured value of a physical variable in the area of the secondary unit and as a function of a first random number; measuring the physical variable in the area of the primary unit to obtain a second measured value; ascertaining a first estimated value for the first random number as a function of the first pieces of information and the second measured value; measuring the physical variable in the area of the primary unit to obtain a third measured value; forming second pieces of information as a function of the first estimated value and the third measured value; transmitting the second pieces of information to the secondary unit.

20. A method for operating a system including at least one primary unit and one secondary unit, wherein the primary unit exchanges pieces of information with the secondary unit, the method comprising:
-
the secondary unit carrying out; forming first pieces of information as a function of at least one first measured value of a physical variable in an area of the secondary unit and as a function of a first random number; transmitting the first pieces of information to the primary unit; receiving second pieces of information from the primary unit; and analyzing the second pieces of information; and the primary unit carrying out; receiving the first pieces of information from the secondary unit; measuring the at least one physical variable in an area of the primary unit to obtain a second measured value; ascertaining a first estimated value for the first random number as a function of the first pieces of information and of the second measured value; measuring the at least one physical variable in the area of the primary unit to obtain a third measured value; forming the second pieces of information as a function of the first estimated value and of the third measured value; and transmitting the second pieces of information to the secondary unit.

21. A primary unit for exchanging pieces of information with a secondary unit, the primary unit comprising:
-
a processor; and a communication interface; wherein the processor is configured to; receive first pieces of information from the secondary unit via the communication interface, the first pieces of information being formed as a function of at least one first measured value of a physical variable in an area of the secondary unit and as a function of a first random number, measure the at least one physical variable in an area of the primary unit to obtain a second measured value, ascertain a first estimated value for the first random number as a function of the first pieces of information and of the second measured value; measure the at least one physical variable in the area of the primary unit to obtain a third measured value; form second pieces of information as a function of the first estimated value and of the third measured value; and transmit the second pieces of information to the secondary unit via the communication interface.
