초록
현재, 인터넷 세상은 스트리밍 서비스의 급격한 보급과 더불어 보안의 취약성 역시 매우 급속도로 증가되는 추세이다. 이러한 스트리밍 보안을 위하여, 본 논문은 웹 스트리밍 콘텐츠에 대한PN 분산 구조 기반 보안프로세서 (SP-WSC)를 제안한다. 제안된 SP-WSC는 기본적으로 PN 분산코드 알고리즘을 웹 스트리밍 특성에 맞게 설계하였기 때문에 다양한 멀티미디어 컨텐츠에 대한보안을 수행할 수 있다. 제안된 SP-WSC는 웹 서버의 보안 취약성과 독립적이다. 그러므로SP-WSC는 웹 서버의 취약성에 무관하게 동작할 수 있다. 즉, SP-WSC는 외부의 비인가 신호에대한 방어력을 증대시켜 멀티미디어 컨텐츠를 보호한다. 또한 부수적으로 이것은 트래픽 과부하에 의한 버퍼링 현상을 감소시킬 수 있는 방안을 제시한다.
Abstract
Nowadays, with the rapid spread of streaming services in the internet world, security vulnerabilities are also increasing rapidly. For streaming security, this paper proposes a PN(pseudo-random noise) distributed structure-based security processor for web streaming contents(SP-WSC). The proposed SP-WSC is basically a PN distributed code algorithm designed for web streaming characteristics, so it can secure various multimedia contents. The proposed SP-WSC is independent of the security vulnerability of the web server. Therefore, SP-WSC can work regardless of the vulnerability of the web server. That is, the SP-WSC protects the multimedia contents by increasing the defense against external unauthorized signals. Incidentally it also suggests way to reduce buffering due to traffic overload.
