"Web$\begingroup$ @kodlu: Additive is an independent classification, I think. Synchronous and asynchronous stream ciphers could also be classified as additive. For example, binary additive would indicate that the cipher gamma output is combined by xor with the plain text to produce the cipher text. I am asking for a different classification, not of how cipher … " - Binary additive stream cipher

WebThe stream ciphers considered in this chapter are binary additive stream ciphers, that is, a ciphertext bitstring is produced by adding a plaintext bitstring and a binary keystream. Thus the security of the cipher depends entirely on the randomness of the keystream. WebA stream cipher is an encryption mechanism that uses a keystream to encrypt a plaintext in bitwise or block-wise manner. A stream cipher is technically specified by choosing a keystream generator and a mode of stream ciphers. ISO/IEC 18033-4:2005 specifies the following ways to generate keystream.
