Abstract: An encoder for encrypting a plaintext into a ciphertext. The encoder has an encoding submodule for acting as a deterministic random bit generator (DRBG) in an offline mode for generating one or more hash-key value candidates, and for acting as a stream encryptor in an online mode for encrypting the plaintext into the ciphertext; a hash key selector for selecting a hash-key value H from the one or more hash-key value candidates; and a hash submodule for generating a MAC tag using at least the ciphertext and the selected hash-key value H. A corresponding decoder is also provided.
