| 摘 要： | PKI应具有可扩展性,因此当用户数量超出系统容量时,可以简单地通过增加PKI实体数量和管理层次来满足用户的需求,实现从原有系统的平滑扩展.本文讨论了PKI的向上、向下和水平扩展等三种方式,提出了一个路径发现方法来减轻PKI扩展对终端用户所造成的影响,以提高PKI服务的可用性.，The expansibility of PKI is expected to have the features that when the amount of user exceeds the system capacity, the users' requirement can still be met by simply expanding the number of PKI entities and management levels, and this expansion should be achieved smoothly from the original system. The upward, downward, and horizontal expansions of PKI are discussed in this paper. A path discovery method is suggested to reduce the effect of PKI expansion to the end-entities, so as to enhance the availbility of PKI services.

A Smooth Expansion Model for PKI |

| Abstract: | The expansibility of PKI is expected to have the features that when the amount of user exceeds the system capacity, the users' requirement can still be met by simply expanding the number of PKI entities and management levels, and this expansion should be achieved smoothly from the original system. The upward, downward, and horizontal expansions of PKI are discussed in this paper. A path discovery method is suggested to reduce the effect of PKI expansion to the end entities, so as to enhance the availbility of PKI services. |
