Public static key agreement key Public static key agreement keys are the public keys of asymmetric key pairs that are used to establish keys (e.g., key wrapping keys, data encryption keys, or MAC keys) and, optionally, other keying material (e.g., Initialization Vectors). Private ephemeral key agreement key
A cryptographic key is called static if it is intended for use for a relatively long period of time and is typically intended for use in many instances of a cryptographic key establishment scheme. Contrast with an ephemeral key .
public/private key - in public key cryptography, separate keys are used to encrypt and decrypt a message. The encryption key (public key) need not be kept secret and can be published. The decryption or private key must be kept secret to maintain confidentiality. Public keys are often distributed in a signed public key certificate.
Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. [1] [2] Key pairs are generated with cryptographic algorithms based on mathematical problems termed one-way functions.

Alice's public key is (,,). To send her a message, Bob chooses a random b and then sends Alice (unencrypted) together with the message encrypted with symmetric key (). Only Alice can determine the symmetric key and hence decrypt the message because only she has a (the private key). A pre-shared public key also prevents man-in-the-middle attacks ...
The HPKP is not valid without this backup key (a backup key is defined as a public key not present in the current certificate chain). [4] HPKP is standardized in RFC 7469. [1] It expands on static certificate pinning, which hardcodes public key hashes of well-known websites or services within web browsers and applications. [5]
A cryptographic key is called ephemeral if it is generated for each execution of a key establishment process. [1] In some cases ephemeral keys are used more than once, within a single session (e.g., in broadcast applications) where the sender generates only one ephemeral key pair per message and the private key is combined separately with each recipient's public key.
