TAILIEUCHUNG - Lecture TCP-IP protocol suite (3/e): Chapter 28 - Behrouz Forouzan

Chapter 28 - Security. In this chapter, you will learn to: Differentiate between two categories of cryptography schemes; understand four aspects of security; understand the concept of digital signature; understand the role of key management in entity authentication; know how and where IPSec, TLS, and PPG provide security. | Chapter 28 Upon completion you will be able to: Security Differentiate between two categories of cryptography schemes Understand four aspects of security Understand the concept of digital signature Understand the role of key management in entity authentication Know how and where IPSec, TLS, and PPG provide security Objectives TCP/IP Protocol Suite CRYPTOGRAPHY The word cryptography in Greek means “secret writing.” The term today refers to the science and art of transforming messages to make them secure and immune to attacks. The topics discussed in this section include: Symmetric-Key Cryptography Asymmetric-Key Cryptography Comparison TCP/IP Protocol Suite Figure Cryptography components TCP/IP Protocol Suite In cryptography, the encryption/decryption algorithms are public; the keys are secret. Note: TCP/IP Protocol Suite In symmetric-key cryptography, the same key is used by the sender (for encryption) and the receiver (for decryption). The key is shared. .
