PSTN multi-function cipher machine enable the encryption and protection service of important call, fax and point-to-point data communication via public and private telephone network, to ensure the safety of transmission over lines, thereby effectively preventing leak loss from the transmission lines of sensitive information. PSTN multi-function cipher machine consists of general purpose key management device, Key Distribution Center and cipher machine. Two ways (online and offline) of key management are supported, general purpose key management device creates key, and distributes cipher algorithm and key offline; the key distribution center is able to distribute key online.
