| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In big data analysis and data mining, confidential data such as personal information is included in the data to be handled, so confidential calculation that can be calculated while protecting privacy is drawing attention. These secret computation protocols are designed by applying public key cryptography that utilizes the difficulty of number theory-based problems such as prime factorization and discrete logarithm problems. When a practical quantum computer is realized, the secret computation protocol is used. The security of the protocol cannot be maintained. Several code-based cryptosystems have been proposed as quantum resistant cryptosystems. Gaborit et al. have proposed a public key cryptosystem HQC based on the quasi-cyclic syndrome decryption problem to the NIST post-quantum cryptographic standardization competition. In this paper, we propose a quantum-resistant secure computation protocol of inner product by applying HQC cryptosystem. | |
