本文讨论了在根据密码学设计保密系统的综合结构时,密钥管理的作用。指出了对标准化的需要,介绍了如何用美国标准ANSIX.17来处理包括密钥交换协议的综合看法的要求。基于使用RSA公开密钥密码,介绍了增强为全自动的密钥管理结构,并且还讨论了利用这些技术后,未来密钥管理结构可能的发展情况。ANSI X9.17标准的应用例子通过对一组拨号计算机口所使用的透明加密系统的简单描述而给出。
This article discusses the role of key management in designing a comprehensive security system structure based on cryptography. Pointed out the need for standardization and introduced how to handle the requirements of a comprehensive view including the key exchange protocol using the American Standard ANSIX.17. Based on the use of the RSA public-key cryptography, an enhancement to a fully automatic key management architecture is introduced, and possible developments of the future key management architecture using these techniques are also discussed. An example of the use of the ANSI X9.17 standard is given by a brief description of the transparent encryption system used by a set of dial-up computer ports.
