WebA one-time pad refers to a system where the sender and receiver both have an identical copy of a pad of pages. Each page contains a different key, usually in the form of a very long random sequence of numbers or letters. Every time a message is sent, a new page from the pad is used and is then carefully discarded by the sender and receiver as ... WebBlock Cipher. A block cipher takes a block of plaintext bits and generates a block of ciphertext bits, generally of same size. The size of block is fixed in the given scheme. The choice of block size does not directly affect to the strength of encryption scheme. The strength of cipher depends up on the key length.
