Difference Between Stream Cipher and Block Cipher in Tabular Form
|In-stream cipher keys and algorithms are applied to each binary digit in a tiara stream, one bit at a time, rather dun encrypting a block of data.
|Block cipher is the main method of encrypting text in which keys and algorithms are applied to block data rather than individual bits like stream cipher.
|A stream cipher is less time-consuming.
|Block cipher is more time-consuming.
|Because of a bit of encrypting at a time. a stream cipher is faster than a block cipher.
|As a block of data is encrypting at a time block cipher is slower than stream cipher.
|Stream Cipher doesn’t use in chaining modes of operation.
|Block Cipher used in chaining modes of operation.
|Hardware implementation is easy using a stream cipher.
|The software implementation is easy using a block cipher.
|One Time Pad is the best example of stream Cipher
|Data Encryption Standard (DES) is the best example of a block cipher.
|Requires less code.
|Requires more code.
|Application: Database,file encryption.
