摘要
为了解决现有的特定源组播应用由于缺乏有效的用户访问控制机制,易受来自恶意用户拒绝服务攻击的问题,提出了一种安全机制,通过规定网络中允许存在的特定源频道地址集合和向用户颁发证书,有效地实现了对用户的访问控制,阻止了恶意用户在控制平面的拒绝服务攻击,保证了特定源组播数据传输的安全。
In order to tackle the security issues in the SSM applications, a secure mechanism is presented. By confining the set of allowed SSM channels and distributing certifications to the pre-defined receivers, the access control of the users is implemented, the DoS attacks is prevented from the malicious users and secure transmission of the multicast data is ensured.
