COMPUTER FUNDAMENTALS

Detailed explanation-1: -The term “Ephemeral key” refers to an asymmetric encryption key designed to be used only for a single session or transaction. Yes (True) In cryptography, the term “Secret algorithm” refers to an algorithm designed in a way that prevents the examination of its inner workings.

Detailed explanation-2: -Definition(s): A short-term key pair used with a public-key (asymmetric-key) algorithm that is generated when needed; the public key of an ephemeral key pair is not provided in a public key certificate, unlike static public keys which are often included in a certificate.

Detailed explanation-3: -Share to Facebook Share to Twitter. Definition(s): A cryptographic key that is generated for each execution of a key-establishment process and that meets other requirements of the key type (e.g., unique to each message or session).

Detailed explanation-4: -Asymmetric encryption, also known as public key encryption, uses a public key-private key pairing: data encrypted with the public key can only be decrypted with the private key.

Detailed explanation-5: -When a key exchange uses Ephemeral Diffie-Hellman a temporary DH key is generated for every connection and thus the same key is never used twice. This enables Forward Secrecy (FS), which means that if the long-term private key of the server gets leaked, past communication is still secure.
