Abstract

This paper proposes embedded software of mechatronic system protection method based on encryption and decryption code of critical program modules during runtime. Secret keys are not stored, but generated by the signature of mechatronic system components. This paper experimentally researches the application of symmetric cryptographic algorithms and the influence of security mechanisms on characteristics (value entropy of secret key, operating speed, and amount of memory) of embedded software.
