The design was based on the security reference model of csss , the architecture of which is a subset of the corba security architecture . lastly , the paper took large efforts to analyze the orb connection management , orb pseudo - object , object reference , and ior for orbit . based on the analysis , the paper implemented the ssl - based security service for orbit by modifying and complementing the orbit source . 提出设计之后,本文比较详细地剖析了orbit中的连接管理、 orb伪对象、 orb初始化、对象引用、 ior ,在此基础上对orbit源码作了大量修改、补充,使之支持ssl的嵌入,最终实现通信加密、用户认证、访问控制和审计等安全服务。
