    Patent Number:
    EP 0482154B1
    Description:

    The device (12) comprises nine coding stages (61.1, 61.2, 69), the first eight of which are of identical construction. It also comprises a coding partial block generation unit (63), an input unit (21) and an output unit (79). It is used for the blockwise coding of a plain text (X) from an information source (11) into a coded text (Y) to be taken to a transmission line (13), whereby a secret code block (Z) is previously introduced via a secure channel (17). Coding takes place stepwise and in p…

    US 5214703
    Description:

    The device (12) comprises nine encryption stages (61.1, 61.2, 69), the first eight of which are constructed identically. It further comprises a key subblock generation unit (63), an input unit (21), and an output unit (79). It serves for the block-by-block encryption of a plaintext (X) proceeding from a message source (11) into a ciphertext (Y) to be delivered on a transmission line (13), wherein a secret key block (Z) is inputted beforehand via a secure channel 17. The encryption is effected…
