| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | As deep learning is used in various applications, the protection of training data, input data, inference results, and training models is becoming an issue. Therefore, deep learning with homomorphic encryption, which can perform operations while keeping the data encrypted, has been attracting attention. However, the computational cost of homomorphic encryption is high, and various speed-up methods such as parallelization and use of hardware accelerators have been proposed. On the other hand, the authors have focused on the fact that deep learning inference does not require a large number of bits, and have proposed a deep learning inference method using a bit-reduced version of homomorphic encryption. In this paper, we first implemented the bit-reduced deep learning process on the homomorphic encryption library SEAL and the deep learning framework HE-Transformer, which uses SEAL, and evaluated them on an Intel Xeon processor. In addition, we implemented and evaluated a bit-reduced version of the homomorphic encryption on a Fujitsu A64FX. As a result of the evaluation, we achieved a maximum speedup of 9.37 times on the Intel Xeon processor compared to the original nGraph-HE2 in the classification of MNIST datasets using CryptoNets. The evaluation of matrix products on Fujitsu A64FX showed a speedup of up to 1.08x compared to Intel Xeon W-2145. | |
