摘　　要：软件版权保护中保密体的更新通常是在不可信的网络环境中完成,合法的用户除了可能会面对非法用户的冒充外,还可能会面临保密体数据受到破坏的风险.针对这一问题,采用了一套特殊的机制来实现安全管理和升级,通过智能卡同升级服务器的双向认证协议,有效地应对了上述风险,同时保证了升级操作的原子性.Updating encrypted component for software rights protection is usually done within an untrusted network environment. The legal user is likely to undertake such risks as the imitation of illegal one and the beach of encrypted components. To address this problem, a special mechanism is adopted to implement safe management and update of encrypted components via the bilateral authentication between smart card and server. This mechanism effectively solves the above risks while making the update operation is an atomic one.
