Binary additive stream cipher
WebSymmetric stream ciphers are used to provide con dentiality for a range of real-time applications. The most common type of stream cipher is the binary additive stream cipher, where encryption and decryption are performed by XORing a binary keystream with the plaintext or ciphertext bitstream, respectively. Web2 MICKEY-128 2.0 Stream Cipher MICKEY-128 2.0 is a hardware-oriented binary additive stream cipher designed to have a long period (264 bit keystream sequence) and high security while main-taining low complexity [2]. Figure 1 shows the overall design of a binary additive stream cipher; the keystream generator is initialized by a secret key ...

Weba binary additive stream cipher. There is abundant theoretical knowledge on stream ciphers, and various design principles for stream ciphers have been proposed and extensively analyzed. For instance, in the modern stream ciphers, a secret key accompanied with a public initialization vector (IV) are used Web6.4 Definition A binary additive stream cipher is a synchronous stream cipher in which the keystream, plaintext, and ciphertext digits are binary digits, and the output function his the XOR function. Binary additive stream ciphers are depicted in …
WebIn the most common form, binary digits ( bits) are used, and the keystream is combined with the plaintext using the exclusive or operation (XOR). This is termed a binary additive … WebWe propose a hardware oriented 80-bit-key binary additive stream cipher. The keystream generator consists of ten nonlinear feedback shift registers whose output sequences are combined by a...
WebA binary additive stream cipher is the term used for a stream cipher which XOR's the bits with the bits of the plaintext. Encryption and decryption require that the synchronus state …
WebStream cipher : Encrypts sequence of plaintext characters, e.g., from binary alphabet {0,1}. Synchronous stream cipher : The output of a pseudorandom generator, the key-stream , is used together with plaintext to produce ciphertext. Additive stream cipher : Ciphertext symbols ci are obtained from plaintext symbols mi and keystream symbols bi by ...
