An encryption method that applies a cryptographic key and algorithm to each binary digit of plain text in order to produce cipher (encrypted) text. This method has become less prevalent in the wake of block cipher techniques.

An algorithm that independent of the plaintext produces a data stream derived from a key, as long as the plaintext which is combined with the plaintext usually with an XOR operation to produce the ciphertext.

A cipher that serially encrypts data, one bit at a time. See also block cipher.

a cipher in which the input data are encryptedone bit (sometimes one byte ) at a time

a cipher in which the input data is encrypted one bit (sometimes one byte) at a time

a method of encrypting data bit-by-bit, as opposed to encoding a contiguous chunk of data all at once like a block cipher

a type of symmetric encryption algorithm

Cipher that operates on a continuous data stream instead of processing a block of data at a time.

A symmetric encryption algorithm that processes the data a bit or a byte at a time with a key resulting in a randomized ciphertext or plaintext. Some commonly used stream cipher algorithms are RC4 and W7.

A cryptographic algorithm that operates on plaintext one bit or byte at a time.

An encryption algorithm that converts a key into a cryptographically-strong keystream, which is then exclusive-ORed with the plaintext..

A pseudo-random number generator that is believed to be cryptographically strong and always produces the same stream of output given the same initial seed (i.e., key). Encrypting with a stream cipher consists of combining the plaintext with the keystream, usually via XOR. See Also: Pseudo-random number generator

The encryption a message by a single bit, byte, or word in a continuous series.

An encryption method that encrypts and decrypts arbitrarily sized messages one character at a time.

A symmetric cipher in which the plaintext strings are encrypted one bit (or byte) at a time, and in which the transformation of successive digits varies during the encryption. See also: block cipher, cipher, symmetric encryption

A stream cipher encrypts in small units, often a bit or a byte at a time, but unlike a basic block cipher the output corresponding to a given input will depend on where in the message it occurs. The simplest type of stream cipher uses a complicated function, which retains state, to generate a psuedo-random sequence which is then combined with the input using a simple operation such as bytewise addition.

A class of symmetric-key encryption operating on the plaintext one byte (or one bit) at a time.

A secret-key encryption algorithm that operates on a bit at a time.

An encryption method that uses continuous input, as opposed to fixed length blocks of data. For contrast, see Block Cipher

A stream cipher works by encryption a message a single bit, byte, or computer word at a time.

In cryptography, a stream cipher is a symmetric cipher in which the plaintext digits are encrypted one at a time, and in which the transformation of successive digits varies during the encryption. An alternative name is a state cipher, as the encryption of each digit is dependent on the current state. In practice, the digits are typically single bits or bytes.
