摘要
在大型科学仪器与技术资源共享系统研究与开发过程中,会遇到信任方面的问题,为解决该问题在加密技术的基础上提出了一种基于数字水印的解决方法.该方法具有以下特性:它保证了身份认证,内容认证,以及行为的不可否认性.通过在发送的资源信息中嵌入与双方信息及传输内容相关的水印,防止第三方伪装成协作的另一方进行欺骗行为,同时也能保证资源的完整性,并借助加密技术保证信息传输的安全.
Information security has become a serious problem in the midst of researching on technology sharing system. An application of watermarking to spectrogram sharing system aiming at the aforementioned question is presented, which is based on encryption technology. Authentication of degree and content ,and undeniableness of behaviors have been guaranteed .As the watermarking, the correlative information coming from both sides is embedded in the resources information that is sent. Encryption is adopted to assure the security of information transmission. By the way, the action of camouflage is prevented and information integrity is available.
