Definition

Asymmetric Cryptography

Asymmetric cryptography is the branch of cryptography in which cryptographic operations use different keys (e.g. one key for encryption, one for decryption).

Communication

When $N$ communication parties want to communicate with each other, they require $N$ key pairs. Every part needs their own key pair and the public keys of the others. Public keys can be distributed over insecure channels (e.g., the Internet).
