In intelligent energy networks and other digital infrastructures, more and more machines will communicate with one another in the future. This development opens up new opportunities for innovative software (e.g. Smart Home, Industry 4.0, etc.). At the same time, communication between machines has to be protected from manipulation. Implementing the highest security demands poses a challenge to applications developers. With the CryptoController from mtG, a security component is available that can be attached quickly and easily by applications developers and safeguards control of intelligent machines in the best possible way.
