Introduction to Computer Networks and Cybersecurity

Chapter 22

Public Key Cryptography, Infrastructure and Certificates

The learning goals for this chapter are as follows:

• Understand the structure and mechanisms involved in the application of public (or asymmetric) key cryptography
• Explore the mathematical relationships employed in the execution of the Diffie-Hellman protocol, the Rivest, Shamir and Adleman (RSA) algorithm and digital signatures
• Learn the techniques employed in the application of elliptic curve cryptography
• Learn the role played by certificates and the certificate authority in the establishment of authenticity in a public key infrastructure
• Gain an understanding of the various standards for public key cryptography, including Elliptic Curve Cryptography (ECC)
• Explore the use ...
