Encryption Technique of a Modern Bank’s Computer Information System

In this paper,the design consideration of encryption technique of a modern bank’s computer information system is presented,which tries to develop the traditional encryption method from 1-D transform to 2-D transform.Since complicated operation and interaction operation are used.the ciphertext is independent of the plaintext linearly EDA-92 adapter of encryption and decryption has been widely applied in different kinds of microcomputer systems.
