Threshold cryptosystem - Wikipedia

WebA data encryption algorithm uses a (secret) key to convert a message into a ciphertext — that is, a scrambled, unreadable version of the message. One can recover the original message from the ciphertext by using a decryption key. In a symmetric encryption algorithm, both the encryption and decryption keys are the same.
