WebbSymmetric keys should be kept secret from other parties than the participants in the scheme. The term "secret key" is often used as a synonym for the symmetric key. The private keys for asymmetric schemes are not shared, but are of course also kept secret, as privacy implies secrecy. Webb10 apr. 2024 · This is done mainly because the symmetric keys are short and encryption/decryption with these keys is faster and computationally cheaper. Now that …
