摘　　要：对传统的对称密码体制中密钥管理技术进行了详细的分析研究,着重讨论了密钥的产生、分配、保护、存储和销毁等环节,并提出了一种基于对称密码体制的密钥分配方案。经分析,该方案安全、简洁和高效,降低了软硬件实现的系统开销,可广泛应用于计算机网络环境。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.
