Security Paradigms

This chapter discusses the main paradigms concerning security. An exhaustive description of all the major algorithms concerned would require a whole book’s length in order not to be shallow. Instead, we will motivate each paradigm in a problem-solving manner, exemplified when applicable with one or two chosen algorithms that are analyzed with the necessary detail. Throughout the chapter, we are going to discuss: trusted computing bases, cryptography, digital signature, digital cash, authentication, protection, and secure communication.
