The Impact of Quantum Computing on Cryptography

Chapter Objectives

After reading this chapter and completing the review questions, you will be able to do the following:

• Understand how quantum computing will impact asymmetric cryptography

• Explain how symmetric cryptography will change after quantum computing

• Appreciate the changes to applications of cryptography that quantum computing will necessitate

Even before starting this book, you were very likely aware that quantum computing would have a substantial impact on cryptography and cybersecurity. In fact, that may have been your impetus for learning more about quantum computing. The most obvious impact of quantum computing will be on asymmetric cryptography. However, that is not ...
