Stream ciphers can be viewed as approximating the action of a proven unbreakable cipher, the one-time pad (OTP). A one-time pad uses a keystream of completely random digits. The keystream is combined with the plaintext digits one at a time to form the ciphertext. This system was proved to be secure by Claude E. Shannon in 1949. However, the keystream must be generated completely at random with at least the same length as the plaintext and cannot be used more than once. Thi… Web20 May 2024 · Data Streams in Data Mining techniques are implemented to extract patterns and insights from a data stream. A vast range of algorithms is available for stream mining.
