Security Mechanism Research Based On The Embedded Streaming Systems

Many embedded streaming media system will be not a independent system with the streaming media technology rapidly developing, specially combining embedded technology , streaming media and internet technology. The inter-connection among systems make the problem for information security standing out. The security performance of user identity authentication and checking the data source's validity for traditional embedded streaming media system is not enough. This paper has designed and implemented one networking steaming media playing system based on embeddedμClinux platform, according to special business requirements. It presents one user identity authentication way based on modified RADIUS protocol and its CHAP protocol. Meanwhile, the system support local play and play in the internet for the limited resource of embedded system. And it has settled the problem that the Qos of playing under the condition of limited bandwidth and uncertain network delay. Additionally, this paper has been presented and implemented digital watermarking detecting algorithm for checking the data source's validity to improve function-complete system. Test results show that the performance of the system meets application requirements, which lays down a necessary base for commercial system deployment.
