Public-key Cryptography

• Public-key cryptography is a cryptographic system that uses pairs of mathematically related keys called a private key and a public key.
  • Private keys are private — no one except its owner should know them.
  • Public keys are public — they may be known to others.
• Key pairs are generated using cryptographic algorithms based on trapdoor one-way functions.
• The first public key cryptosystem was the RSA system of Rivest, Shamir, and Adleman, which they published in 1978

Uses

• Public-key Encryption
• Digital Signature

Examples
