Method and device for monitoring a bus system and bus system
First Claim
1. A method of monitoring a bus system having at least two users, comprising:
- structuring at least one of the at least two users of the bus system as at least one authorized user that monitors a data transmission on the bus system;
transmitting an identifier for each data transmission on the bus system, the identifier being uniquely allocatable to one of the at least two users;
causing the at least one authorized user to compare the identifier with another identifier; and
if the identifier and the other identifier are the same, implementing a measure in order to prevent an execution of the data to be transmitted if the data transmission is initiated by a user other than the at least one authorized user.

Abstract
A method and device for monitoring a bus system and bus system having at least two users, of which at least one is structured as an authorized user and monitors the data transmission on the bus system, an identifier being transmitted and the identifier being uniquely allocatable to one user for each data transmission on the bus system, the at least one authorized user comparing the identifier with a specified identifier, and if both identifiers are the same taking measures in order to prevent an execution of the data to be transmitted if the data transmission is initiated by a user other than the at least one authorized user.

8. A device for monitoring a bus system having at least two users, comprising:
-
an arrangement for structuring at least one of the at least two users of the bus system as at least one authorized user that monitors a data transmission on the bus system;
an arrangement for transmitting an identifier for each data transmission on the bus system, the identifier being uniquely allocatable to one of the at least two users;
an arrangement for causing the at least one authorized user to compare the identifier with another identifier; and
an arrangement for, if the identifier and the other identifier are the same, implementing a measure in order to prevent an execution of the data to be transmitted if the data transmission is initiated by a user other than the at least one authorized user.

9. A bus system, comprising:
-
a monitoring arrangement for monitoring the bus system;
at least two users;
an arrangement for structuring at least one of the at least two users of the bus system as at least one authorized user that monitors a data transmission on the bus system;
an arrangement for transmitting an identifier for each data transmission on the bus system, the identifier being uniquely allocatable to one of the at least two users;
an arrangement for causing the at least one authorized user to compare the identifier with another identifier; and
an arrangement for, if the identifier and the other identifier are the same, implementing a measure in order to prevent an execution of the data to be transmitted if the data transmission is initiated by a user other than the at least one authorized user.
