Nowadays, the financial organizations mostly employs SDH and ATM data network and provides fixed(virtual) circuit for connection of various departments and branches. And data from intranet, without any protection, is transferred over the international circuit, thus giving the hacker a chance to use various intrusion measures, such as intercepting, electromagnetic eavesdropping. Therefore, it is necessary to use network encryptor and provide various security functions, including access control, connectionless integrity, authentication of data source, load confidentiality, and confidentiality of limited traffic, thus remedying the security loopholes brought along by TCP/IP protocol system.
