The contents of this chapter include all of the following: Diffie-Hellman key exchange, ElGamal cryptography, Elliptic curve cryptography, Pseudorandom Number Generation (PRNG) based on Asymmetric Ciphers. | Data Security and Encryption (CSE348) Lecture slides by Lawrie Brown for “Cryptography and Network Security”, 5/e, by William Stallings, briefly reviewing the text outline from Ch 0, and then presenting the content from Chapter 1 – “Introduction”. Lecture # 17 Review have considered: RSA algorithm, implementation, security Chapter 4 summary. Chapter 10 – Other Public Key Cryptosystems Opening quote. Amongst the tribes of Central Australia every man, woman, and child has a secret or sacred name which is bestowed by the older men upon him or her soon after birth, and which is known to none but the fully initiated members of the group. This secret name is never mentioned except upon the most solemn occasions; to utter it in the hearing of men of another group would be a most serious breach of tribal custom. When mentioned at all, the name is spoken only in a whisper, and not until the most elaborate precautions have been taken that it shall be heard by no one but members of the group. The native thinks that a stranger knowing his secret name would have special power to work him ill by means of magic. —The Golden Bough, Sir James George Frazer Opening quote. Diffie-Hellman Key Exchange This chapter continues our overview of public-key cryptography systems (PKCSs) Begins with a description of one of the earliest and simplest PKCS Diffie-Hellman key exchange This first published public-key algorithm appeared in the seminal paper by Diffie and Hellman This chapter continues our overview of public-key cryptography systems (PKCSs), and begins with a description of one of the earliest and simplest PKCS, Diffie-Hellman key exchange. This first published public-key algorithm appeared in the seminal paper by Diffie and Hellman that defined public-key cryptography [DIFF76b] and is generally referred to as Diffie-Hellman key exchange. The concept had been previously described in a classified report in 1970 by Williamson | Data Security and Encryption (CSE348) Lecture slides by Lawrie Brown for “Cryptography and Network Security”, 5/e, by William Stallings, briefly reviewing the text outline from Ch 0, and then presenting the content from Chapter 1 – “Introduction”.
