Research on Security of SIP Conferencing
Existing research on the SIP conferencing always only focuses on system architecture,utility function and running performance,but overlooks security issue in conferences.The security problems mainly summarize to two kinds,which are confidentiality problems caused by leakage and reliability problems caused by SIP attacks.According to these problems in SIP conferencing,this paper proposes a series of methods to advance SIP standard conferencing framework.The conference confidentiality technology research includes password security and media security.We use moderator's authentication and encryption to achieve double insurance.The conference reliability research mainly includes standardized examination,protocol extensions and SIP flooding intrusion detection.We verify the reasonableness via the experiment at last.
