| 摘 要： | 针对多媒体视频和音频文件在传统数据加密结构下速度慢且不能容忍信道的错误,以及由微小数据解密错误需重发信息导致系统传输能力下降的问题,基于容错加密提出了一种高效选择性容错加密方案.分析结果表明,该方案在质量不高的通信信道中能够改进网络的传输能力,且解密后的信道错误对原始多媒体视频和音频文件仅产生线性影响.

| Abstract: | Based on idea of error-tolerant encryption,an efficient selective error-tolerant encryption scheme is presented to overcome the drawbacks of multimedia video and audio under the traditional data encryption framework:not only the playing of multimedia files has slow speed but also it unable to tolerate any uncorrectable channel errors,and a little data decryption error may require to resent the information so to cause the reduction of system transmitting capability.The analysis shows that the proposed scheme... |
