Hardware platform and method based on homomorphic encryption gate bootstrap technology

According to the hardware platform and method based on the homomorphic encryption gate bootstrap technology, hardware implementation is conducted on an algorithm of the hardware platform on the basis of an original TFHE scheme, and a specific hardware architecture is provided. According to the platform, noise refreshing can be quickly and accurately carried out on the ciphertext of which the noise reaches the noise margin after homomorphic operation, so that the noise is reduced to carry out subsequent homomorphic operation. The method is mainly applied to related applications of homomorphic encryption needing rapid bootstrap, such as cloud computing, cloud neural network prediction and the like. 发明提供了一个基于同态加密门自举技术的硬件平台及方法，该硬件平台在原TFHE方案的基础上对其算法进行了硬件实现，并给出了具体的硬件架构。该平台能够快速准确的对经过同态运算后噪声达到噪声容限的密文进行噪声刷新，使得其噪声下降以进行后续的同态运算。该发明主要应用于需要快速自举的同态加密的相关应用，例如云上计算、云上神经网络预测等。
