Web13 de out. de 2012 · A stream cipher is an encryption system which works over a given sequence of input bits. Most stream ciphers work by generating from the key a long sequence of random-looking bits, which are then combined (by bitwise XOR) with the data to encrypt. This is a (crude) emulation of one-time pad.

Web16 de jun. de 2011 · AES is a block cipher, i.e. a function which, given a key, maps block values (of 128 bits, in the case of AES) to other block values of the same size. To encrypt a message, one must use the block cipher in a chaining mode which tells how the input data should be split and encrypted and assembled again. Almost all modes allow for …
