SECURITY SYSTEM AND METHOD FOR SECURING THE INTEGRITY OF AT LEAST ONE ARRANGEMENT COMPRISING MULTIPLE DEVICES
First Claim
1. A security system for securing the integrity of at least one arrangement comprising multiple devices, for example of at least one network and/or of at least one computer system, characterized inthat the devices communicate with each other, in particular by exchanging messages between and among each other,that each device comprises at least one respective security unit[a] for performing at least one authentication by means of exchanged messages and[b.i] in case of a valid authentication for enabling operation of the respective device and/or of at least one of the other devices and[b.ii] otherwise, in particular in case of an invalid authentication, for disabling operationof the respective device and/orof at least one of the other devices and/orof at least one undefined and/or unauthorized device in particular of at least one device comprising no such security unit

Abstract
In order to provide a security system (100; 100′) for securing the integrity of at least one arrangement comprising multiple devices (10, 12; 10a, 12a, 12b, 12c), for example of at least one network and/or of at least one computer system, wherein manipulation of the arrangement comprising these multiple components or devices (10, 12; 10a, 12a, 12b, 12c) is prevented, it is proposed that the devices (10, 12; 10a, 12a, 12b, 12c) communicate with each other, in particular by exchanging messages (20) between and among each other, that each device (10, 12; 10a, 12a, 12b, 12c) comprises at least one respective security unit (30, 32) [a] for performing at least one authentication by means of exchanged messages (20) and [b.i] in case of a valid authentication for enabling operation of the respective device (10; 10a) and/or of at least one of the other devices (12; 12a, 12b, 12c) and [b.ii] otherwise, in particular in case of an invalid authentication, for disabling operation of the respective device (10; 10a) and/or of at least one of the other devices (12; 12a, 12b, 12c) and/or—of at least one undefined and/or unauthorized device (14), in particular of at least one device comprising no such security unit (30, 32).
