The public-key setting One party generates a pairof keys: public key pk and private key sk Public key is widely disseminated Private key is kept secret, and shared with no one Private key used by the party who generated it; public key used by anyone else Also called asymmetric
- William Stallings, Cryptography and Network Security 5 e
The topics of cryptographic key management and cryptographic key distribution are complex, involving cryptographic, protocol, and management considerations The purpose of this chapter is to give the reader a feel for the issues involved and a broad survey of the various aspects of key management and distribution For more information,

Diffie-Hellman key exchangeThe math: discrete logarithm in action Solve for 𝑘,given values 𝑝, 𝑔, 𝑎′, 𝑏′ and knowing: 𝑘=𝑔𝑎𝑏=𝑔𝑏𝑎 𝑎′=𝑔𝑎 mod 𝑝 𝑏′=𝑔𝑏 mod 𝑝 𝑘=(𝑏′)𝑎 mod 𝑝 𝑘=(𝑎′)𝑏 mod 𝑝 Finding 𝑘 is easy if 𝑎 or 𝑏are known Quickly solved by brute force if 𝑝=3 and𝑔=2

Public key cryptography came about as a solution to two problems: Key Distribution With private key cryptosystems, a major problem is how keys are distributed to a set of message senders and recipients
- Key Characteristics - DAU
Key Characteristics are not the same as Key Performance Parameters KPPs are derived by the user and identify the important performance parameters and sets minimum thresholds Users determine the KPPs, while design and manufacturing experts determine the Key Characteristics
- PowerPoint Dichotomous Key
What is a dichotomous key? A dichotomous key is a tool that allows the user to determine the identity of items in the natural world, such as trees, wildflowers, mammals, reptiles, rocks, and fish Keys consist of a series of choices that lead the user to the correct name of a given item "Dichotomous" means "divided into two parts"
- Key Exchange Protocols - Stanford University
B returns a keyed hash of the Diffie-Hellman exponential that he receives in the first message from A Only after A returns the cookie in the third message does B create state and perform expensive public key operations B’s identity is protected against passive adversaries Properties accumulate as a derivation proceeds
