中文摘要：
为可伸缩的匿名的通讯系统(囊) 的新体系结构被建议。用户被划分成不同 sub-blenders 管理的几亚群，并且所有 sub-blenders 被主要混合的使用管理二个层管理计划。成员的身份信息在不同 sub-blenders 上被散布，它让每个成员保留信息和网络超载极大地减少的少得多。匿名和新计划的开销被分析并且与的相比拥挤，它证明当匿名几乎没被降级时，为新计划的存储和网络开销的费用大部分减少。实验结果也证明新系统建筑学是很好可伸缩的。当 P (IsvH1+) 的价值仅仅增加 0.0010.020 时，到人群的囊的管理费用的比率关于 1:25，它证明囊几乎与人群一起保留一样的匿名。
英文摘要：
A new architecture for scalable anonymous communication system（SACS） was proposed. The users were divided into several subgroups managed by different sub-blenders, and all sub-blenders were managed by the main-blender using two layers management scheme. The identity information of members are distributed on different sub-blenders, which makes each member keep much less information and network overload greatly reduce. The anonymity and the overhead of the new scheme were analyzed and compared with that of Crowds, which shows the cost of storage and network overhead for the new scheme largely decreases while the anonymity is little degraded. The experiment results also show that the new system architecture is well scalable. The ratio of management cost of SACS to that of Crowds is about 1：25 while the value of P（1｜H1＋） only increases by 0.001-0.020, which shows that SACS keeps almost the same anonymity with Crowds.
