Researches on Scalable Architecture for Security Information Distribution Service

Distribution of security information is one of the important infrastructures for information security of Internet. There are some problems in the existing security information distribution (SID) Services on Internet such as single point of failure, denial of service under flash crowd and the bad time efficiency of information distribution. In this paper we propose two scalable architectures for SID service based on peer-to-peer technology and apply them to the SID service of the China Education and Research Network (CERNET).
