使用

需要使用 编译器gcc > 10 (unicode 编码)

HE3DB

This code is the implmentation of the paper HE3DB: An Efficient and Elastic Encrypted Database via Arithmetic-and-Logic Fully Homomorphic Encryption.

错误

gcc11 好像需要使用-march=native选项应该可以启用针对本地CPU的优化和特性检测，包括SSE2和AES指令集, 同时也需要查看 cpu 有相关指令

lscpu | grep sse2
lscpu | grep aes

没有相关指令则关闭该选项 RANDEN

option(USE_RANDEN "Use randen as CSPRNG" OFF)
