| Abstract: | The key management technique in the traditional symmetrical cipher system is analyzed in detail. The generation, apportionment, protection, memory and destruction of the key are particularly discussed. Moreover a distribution of key scheme based on the symmetrical key system is presented. Further detailed analysis shows its brevity, security, and high efficiency. It also reduces system overheads of software and hardware application. The scheme is used widely in network environment. |
