Stream ciphers are preferred over block ciphers since they require less buffer space, less complex hardware structure and also permits the possibility of real time encryption for time critical applications. Besides this, the different implementation properties of stream ciphers restrict the side channel cryptanalysis

View Academics in ZUC stream cipher, FPGA implementation, VHDL on Academia.edu stream ciphers, such as RC4 and CryptMT [2], use a time-varying transformation to encrypt individual bits of plaintext; block ciphers, such as AES and DES, operate with a ﬁxed transformation on large blocks of plaintext data. In general, stream ciphers have lower complexity and higher throughput than block ciphers A stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream. In a stream cipher, each plaintext digit is encrypted one at a time with the corresponding digit of the keystream, to give a digit of the ciphertext stream. Since encryption of each digit is dependent on the current state of the cipher, it is also known as state cipher. In practice, a digit is typically a bit and the combining operation is an exclusive-or. The. The VHDL reference implementation along with optimized versions of the stream cipher Grain-128AEAD.

- Stream cipher uses confusion to ensure that it doesn't give clues about the plain text, whereas block cipher uses both confusion and diffusion. A stream cipher is faster than a block cipher, whereas a block cipher is slower. In a stream cipher, one key is used for one time, whereas in a block cipher, the key can be reused
- Stream Cipher Definition. A Stream Cipher is an encryption method and is part of symmetric cryptography. With stream ciphers or stream ciphers, the data encrypted in one piece. This type of encryption is not that common. Block ciphers are used much more frequently for symmetric encryption. Stream ciphers are less well than block ciphers
