An approach for integrity assurance in Time-triggered Ethernet

Abstract

In communication systems, integrity is the ability of a system to detect faults and achieve a fail-safe state during operation, and is one of the important attributes of credibility. Currently, there is no effective integrity assurance mechanism in Time-Triggered Ethernet (TTE). This paper combines the principles of cryptography, designs TTE switch with integrity guarantee mechanism, and builds a simulation platform to verify the design implementation. The simulation results show that the mechanism effectively implements the data integrity guarantee of TTE and improves the reliability of the TTE system.
