Confidential data exchange over the Internet is becoming increasingly important. Many business sectors already rely on encrypted communication, such as online banking and shopping. In particular, the use of asymmetric cryptographic methods to secure communication requires enormous computing power. Internet server operators use specialized hardware accelerator cards to manage this demand. A disadvantage of this crypto hardware is the high acquisition costs. The growing need is driving the search for alternatives. Modern 3D graphics cards have become particularly powerful and increasingly flexible in recent years. Modern science is already utilizing them today, for example, for real-time calculations in high-resolution computed tomography. Their significant sales volume has made them affordable mass-market products.
