- Abstract
The use of cryptography has become increasingly important in recent years. Currently there are several good methods
for encryption like AES and DES. Both of these algorithms require several rounds to encrypt a relatively small block of
data. Stream ciphers, like Vigenere and Caesar in particular, only require one round. The Vigenere and Caesar
ciphers, however, can be easily broken. Improved version of the Vigenere algorithm is obtained by adding random bits
of padding to each byte to diffuse the language characteristics and this make the cipher unbreakable. In this paper we
will present an efficient method for hardware implementation of the improved Vigenere algorithm.
