中文摘要:

我们基于活动代理人建议一个数字权利管理(DRM ) 系统保护内容供应商的版权。在系统,内容供应商从一个原来的代理人创造一倍有限的黑盒子并且派遣它到用户目的强制 DRM 函数。黑盒子是能在某个时间从恶意的用户抵抗攻击的一个代理人间隔。由于数字权利再分配支持,其权利属于再分配范畴的用户能把他的权利转移到另外的用户。而且由介绍公钥基础结构(PKI ) 和证书权威(CA ) 角色,会议的安全能被保证。有传统的 DRM 系统的系统安全和性能和比较的分析被给。

英文摘要:

We propose a digital rights management (DRM) system based on mobile agent to protect the copyrights of content providers. In the system, the content provider creates a time limited blackbox out of an original agent and dispatches it to the user end to enforce DRM functions. The blackbox is an agent that can resist the attacks from the malicious user in a certain time interval. Owing to digital rights redistribution support, the user whose rights belong to redistribution category can transfer his rights to other users. Moreover, by introducing public key infrastructure (PKI) and certificate authority (CA) role, the security of the session can be ensured. An analysis of system security and performance and a comparison with traditional DRM system is given.
