TAILIEUCHUNG - Lecture Network security: Chapter 18 - Dr. Munam Ali Shah

The topics discussed in this chapter are: RSA algorithm, introduction to pseudorandom numbers, some pseudorandom number generators, attacks on pseudorandom generators, tests for pseudorandom functions, true random generators. | Network Security Lecture 18 Presented by: Dr. Munam Ali Shah Summary of the Previous Lecture We have discussed public/ asymmetric key cryptography in detail We have explored how confidentiality, authentication and integrity could be achieved through public key cryptography Different names Public key cryptography Asymmetric key cryptography 2 key cryptography Presented by Diffie & Hallman (1976) New directions in cryptography 3 Essential steps Each user generates its pair of keys Places public key in public folder Bob encrypt the message using Alice’s public key for secure communication Alice decrypts it using her private key Outlines of today’s lecture RSA Algorithm Introduction to Pseudorandom Numbers Some Pseudorandom Number Generators Attacks on Pseudorandom generators Tests for pseudorandom functions True Random generators Objectives You would be able to understand the a public key cryptography algorithm. You would be able to present an understanding of the random numbers and .
