Abstract |
Stream ciphers in general tend to be weak since they lack the benefit of diffusion. It is for this reason alone that the Vigen?re cipher is able to be cracked. Without the ability to detect cycles, and intern, derive the key length, the Vigen?re cipher would be highly secure. By adding a few bits of random padding to each byte, one can diffuse the statistical retentiveness found within most messages. The exact quantity of pad will be determined by a one way function in an effort to eliminate the distinguishably of the message bits from the padded random bits. This methodology moderately increases the size of the cipher text, but greatly increases the security of the cipher |
