Cryptography applied to automotive use cases

The study of mathematical procedures that process or alter data to conceal and authenticate information and its sources is known as cryptography. The field has had a fascinating past with a decisive influence in protecting national secrets during critical periods of world history. The great advances in Information Technology (IT) called for stronger cryptographic methods as an enabling technology for greater connectivity and information sharing. More recently, cryptography has gained an added sense of allure due to the rise of cryptocurrency, which has garnered the attention of millions of people from all walks of life. In this section, we will try to demystify some of the basic concepts of cryptography and show how to apply them to common automotive use cases to achieve some of the security objectives presented earlier in this chapter. This section is meant to give you an introduction to important concepts that should make it easier for...
