摘要

同态加密方案领域的新研究使得使用不同的技术和编程语言实现各种方案成为可能。在本文中,我们描述了使用Python和GMPY2库实现的DGHV方案变体。该方案最早由van Dijk等人于2010年提出,后来由Coron在2011年和2012年修改为两个变体,以计算能力为代价减少了令人望而却步的公钥大小。除此之外,本文还将这些实现与先前Coron的第一个变体的实现进行了比较。

Implementation of the fully homomorphic encryption scheme over integers with shorter keys
New researches in the field of homomorphic encryption schemes have made it possible to implement a variety of schemes using different techniques and programming languages. In this paper we describe the implementation of a DGHV scheme variant using Python and the GMPY2 library. This scheme was first proposed in 2010, by van Dijk et al, and later modified into two variants by Coron in 2011 and 2012, which reduced the prohibitive size of the public keys, at the cost of computational power. Besides that, this paper also presents a comparison of these implementations with the previous implementation of Coron's first variant.
