Abstract

This paper discusses encryption operations that selectively encrypt content-carrying segments of multimedia data stream. We propose and analyze three techniques that work in different domains, namely, a syntax-aware selective bitstream encryption tool with bit stuffing, a generalized index mapping encryption tool with controlled overhead and an intra-bitplane encryption tool compatible with fine granularity scalable coding. The designs of these proposed encryption operations take into consideration the inherent structure and syntax of multimedia sources and have improved friendliness to communications, compression and computation.
通信友好的多媒体加密
本文讨论了对多媒体数据流中承载内容的部分进行选择性加密的加密操作。我们提出并分析了在不同领域工作的三种技术,即具有位填充的语法感知选择性比特流加密工具,具有控制开销的广义索引映射加密工具和兼容细粒度可扩展编码的位平面内加密工具。这些加密操作的设计考虑了多媒体源的固有结构和语法,提高了对通信、压缩和计算的友好性。
