of the operations as if they had been performed on the plaintext. To reduce the communication overhead and computation overhead, homomorphic encryption is chosen to encrypt the data. Homomorphic encryption can support addition, subtraction and multiplication in encrypted domain as formulas(1)–(3)....
同态加密-Homomorphic encryption 同态加密(Homomorphic encryption)是一种加密形式,它允许人们对密文进行特定的代数运算得到仍然是加密的结果,将其解密所得到的结果与对明文进行同样的运算结果一样。换言之,这项技术令人们可以在加密的数据中进行诸如检索、比较等操作,得出正确的结果,而在整个处理过程中无需对数据进行解密...
通常RLWE密文定义在 Rq×Rq 上,这里 Rq=Zq[X]/(XN+1) 。又因为一个RLWE密文可以拆分成 N 个定义在 ZqN×Zq 上的LWE密文(这些LWE密文都是由同一个密钥加密的),所以只需要在estimator.py脚本中指明LWE维度N,模数q,和噪声标准差stddev即可算得具体的攻击复杂度。 参考 ^https://en.wikipedia.org/wiki/Lear...
