Key Generation
Public key cryptography relies on algorithms for generating public/private key pairs such that it is computationally infeasible to determine a private key from a public key.Key Exchange
The primary advantage of public key cryptography is that it doesn't require a secure exchange of secrets to work. This is ideal for applications such as web browsing where a large number of clients and services need to connect to each other securely.Public key cryptography tends to be computationally complex. Therefore, it is often used to exchange symmetric keys that are used for one session and then discarded. This is done because symmetric encryption is generally faster.| Overview: Public Key Cryptography | ||
Type | ||
Definition | Encryption based on pairs of public and private keys whereby any sender can encrypt a message with a public key that can only be read with the corresponding private key. | |
Value | Enables encryption between a large number of clients and services without the need to share private keys. | |
