Quizplus · Accepted Answer

Iterated block ciphers are constructed by composing several simpler functions, and they are also known as product ciphers. Hybrid ciphers combine both symmetric and asymmetric encryption methods. Stream ciphers encrypt a stream of information, while group ciphers are a type of encryption scheme used in group communication settings.
