1/5/2024 0 Comments Block cipherStream Cipher doesn’t consist of a complex algorithm or process as a Block Ciphers.Stream cipher requires less code than block cipher.In a stream cipher, one key is used for one time, whereas in a block cipher, the key can be reused.A stream cipher is faster than a block cipher, whereas a block cipher is slower.Stream cipher uses confusion to ensure that it doesn’t give clues about the plain text, whereas block cipher uses both confusion and diffusion.Block cipher relies on transposition techniques like rail-fence technique, columnar transposition technique, Vernam cipher, and book cipher.Stream cipher relies on substitution techniques like Caesar cipher, modified Caesar cipher, monoalphabetic cipher, homophonic cipher, polygram substitution cipher, polyalphabetic cipher, Playfair cipher, and hill cipher.In a stream cipher, the decryption is also done bit by bit, whereas, in block cipher, it is done by block by block.In a stream cipher, the encryption is done bit by bit, whereas, in block cipher, it is done block by block. ![]() Let us discuss some of the major key differences between Stream Cipher vs Block Cipher : Key Differences Between Stream Cipher vs Block Cipher Web development, programming languages, Software testing & others Head to Head Comparison Between Stream Cipher vs Block Cipher (Infographics)īelow are the Top 11 comparisons between Stream Cipher vs Block Cipher : Start Your Free Software Development Course A block cipher can be created from a given stream cipher by just encrypting a whole block with the stream cipher, but a stream cipher from a block cipher cannot be created. Stream Ciphers encrypts by Taking one digit/element continuously and produces output one element at a time. So basically there are two most popular types for encryption and decryption of the text. The decryption is also proceeded by one block at a time. The decryption is also proceeded by one bit at a time.Ī block cipher is a technique that involves the encryption of one block of plain text at a time. ![]() A stream cipher is a technique that involves the encryption of one plain text bit at a time. We are also going to discuss the difference between stream cipher and block cipher. Both techniques are used for the same purpose, but there is a difference in their methods and work. Both methods have their purpose and methods. to convert the plain text to ciphertext and cipher text to plain text. In this article, Stream Cipher vs Block Cipher, both stream Cipher and block cipher are techniques used for encryption and decryption, i.e. Difference Between Stream Cipher vs Block Cipher
