-完全同态加密（FHE）允许对加密数据进行安全计算。不幸的是，巨大的内存大小、计算成本和带宽需求限制了它的实际应用。我们提出BASALISC，这是一个硬件加速器的架构家族，旨在大幅加速云中的FHE计算。BASALISC是第一个实现支持全打包引导的BGV方案-支持任意深度计算所需的噪声去除能力。我们提出了一个通用版本的引导，可以直接在我们的硬件中实现，用蒙哥马利乘法器实例化，节省46%的硅面积和40%的功率
—Fully Homomorphic Encryption (FHE) allows for secure computation on encrypted data. Unfortunately, huge memory size, computational cost and bandwidth requirements limit its practically. We present BASALISC, an architecture family of hardware accelerators that aims to substantially accelerate FHE computations in the cloud. BASALISC is the first to implement the BGV scheme supporting fully-packed bootstrapping – the noise removal capability necessary to support arbitrary-depth computation. We propose a generalized version of bootstrapping that can be implemented directly in our hardware, instantiated with Montgomery multipliers that save 46% in silicon area and 40% in power
