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.
