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 ... WebMar 27, 2024 · Stream ciphers are designed to produce a very long sequence of bits, so there is no issue here. The real issue is reusing a (key,nonce) pair more than one. This can result in the loss of confidentiality. In the most common form, binary digits are used ( bits ), and the keystream is combined with the plaintext using the exclusive or operation (XOR). This is termed a binary additive stream cipher . In a synchronous stream cipher, the sender and receiver must be exactly in step for decryption to be successful. See more A stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream (keystream). In a stream cipher, each plaintext digit is encrypted one at a time with the … See more Binary stream ciphers are often constructed using linear-feedback shift registers (LFSRs) because they can be easily implemented in hardware and can be readily analysed mathematically. The use of LFSRs on their own, however, is insufficient to … See more For a stream cipher to be secure, its keystream must have a large period, and it must be impossible to recover the cipher's key or internal state from the keystream. Cryptographers … See more 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 See more A stream cipher generates successive elements of the keystream based on an internal state. This state is updated in essentially two ways: if the state changes independently of the plaintext or ciphertext messages, the cipher is classified as a synchronous … See more Instead of a linear driving device, one may use a nonlinear update function. For example, Klimov and Shamir proposed triangular functions (T-functions) with a single cycle on n-bit words.
