Abstract
In this paper, it is shown how to adapt certain
matrix transformation to create a novel asymmetric
block encryption scheme. The proposed scheme is
especially useful for encryption of large amounts of
data, such as digital images. First, a pair of keys are
given by using matrix transformation; Second, the
image is encrypted using private key in its transformation
domain; Finally the receiver uses the public
key to decrypt the encrypted messages. This scheme
satisfies the characters of convenient realization, less
computation complexity and good security. |
