基于RLWE的全同态加密方案OA北大核心CSCDCSTPCD
Fully homomorphic encryption scheme from RLWE
基于Kristin Lauter等人的somewhat同态方案，提出“带密钥转换的重线性化技术”。结合该技术与“模转换”，设计了一个基于RLWE的非自举的层次化全同态加密方案。该方案的同态操作简单，而且给出的平凡门操作使得电路层结构更清晰。最后利用自举技术作为优化提升了方案的同态运算能力。
Based on the somewhat homomorphic scheme of Kristin Lauter et al. a new technique, called Relinearization with key switching was presented. Combining this technique with modulus switching, a (leveled) fully homomorphic en-cryption scheme without bootstrapping from RLWE were designed. Homomorphic operations of this scheme is simple, and trivial gate operation given in the scheme can make level structure of circuit clearer. Finally, bootstrapping was used as o…查看全部>>
