Secondly, most of typical scheme for MANET multicast reking are based inbalanceable key tree, the most import problem of multicast reking is providingforward security when member leaves and backward security when member join, then,how to improve efficient of multicast reking, decrease the cost of reking, is the coreproblem of balanceable key tree for MANET multicast reking.

对于大规模自组织网络，采用完全集中式或完全分布式的组****管理的方式容易形成系统单一失效点、产生网络分割、不同步等问题，实际应用中宜采用结合集中式和分布式优点的分散式的组****管理框架，子组中心管理和用户子组管理是框架的两个管理层次，对子组中心管理关注的是组****分发的安全性和效率，如何实现分布式身份可验证的组****分发是自组织网络组****管理的关键问题。

To discuss on a new way of preventing malpractice and dispute,to lower the atio of medical accident,and to give reference to improving management under new situation,the author put forward view points from links influencing medical safe as followed:Firstly,improve quality of health service stop revent medical malpractice and dispute.Secondly,streng then safe education to firm the foundation of prevention.Thirdly,enforce management of military wounded to prevent their misdeed. Fourthly,pay attention to key position and key link to actualize the regulations of medical safe management.

为了探讨医疗事故和纠纷防范的新路子、新方法，降低医疗安全事故的发生率，以及为新形势下提高医疗安全管理水平提供参考，本文针对公立医院特点，从影响医疗安全的各环节入手，提出了防范医疗事故和纠纷的有效措施：一是努力提高医护质量，从源头预防各类医疗事故和纠纷的发生；二是大力加强安全教育和作风建设，打牢医疗安全防范的思想根基；三是加强对病员管理，预防病员违法违纪；四是抓住重点部位、关键环节安全管理，制定并确保各项医疗安全管理制度落到实处。

Forward security is achieved by an evolutional parameter,which is updated with the evolution of time segment,and the group public key and members' certificates are updated along with the parameter.If a menber's private key is betrayed,the attackers can't forge the member's previous signatures.Revocation is achieved by Certificate State List,which needs the group center to update the CSL in real time,and the previous signatures of the revocative members are still valid.

前向安全性通过一个进化参数实现，进化参数随着时间段的变化而进化更新，从而使群公钥和成员证书进化更新，即使成员密钥泄露，攻击者也无法伪造该成员以前的签名；成员撤消通过证书状态列表实现，只需群中心实时更新成员证书状态列表，被撤消成员其以前的签名仍然有效。
