关于“保机密图像搜索:同态加密与保距离随机化的比较研究”一文的注记

A Note on "Confidentiality-Preserving Image Search: A Comparative Study Between Homomorphic Encryption and Distance-Preserving Randomization"

Zhengjun Cao, Lihua Liu

摘要:

最近,Lu等人提出了两种基于加性同态加密的图像搜索方案[IEEE Access,2(2014),125-141]。我们注意到这两个方案都是有缺陷的,因为:(1)第一个方案根本没有利用加法同态性质;(2)第二个方案中的加法同态加密是不必要的,可以用更有效的对称密钥加密来代替。

英文摘要:

Recently, Lu et al. have proposed two image search schemes based on additive homomorphic encryption [IEEE Access, 2 (2014), 125-141]. We remark that both two schemes are flawed because: (1) the first scheme does not make use of the additive homomorphic property at all; (2) the additive homomorphic encryption in the second scheme is unnecessary and can be replaced by a more efficient symmetric key encryption.
