Compressing Encrypted Data by Siva Theja Maguluri
在带宽受限的不安全通道上传输冗余数据的经典方法是首先对其进行压缩，然后对其进行加密。本报告调查了在不影响加密效率或信息保密性的情况下颠倒压缩和加密顺序的新颖性。
尽管违反直觉，但可以使用带有辅助信息的源代码编码原则来使这种逆转成为可能。
在某些场景下，不需要比传统系统更多的密钥随机性
(The classical way of transmitting redundant data over a bandwidth constrained insecure channel is to first compress it and then encrypt.
This report investigates the novelty of reversing the order of compression and encryption, without compromising either the encryption efficiency or the information secrecy.
Although counter intuitive, principles from source coding with side information, can be used to make this reversal possible.
In certain scenarios, no more randomness in key is required than the traditional system)
