ENCRYPTION APPARATUS, METHOD FOR ENCRYPTION, METHOD FOR DECRYPTION AND COMPUTER-READABLE RECORDING MEDIUM |
| 摘要 |
An encryption apparatus includes a setting generator configured to generate an increasing function parameter regarding a predetermined one-way increasing function and a secret key necessary for encryption, and an encryptor configured to generate a first order-preserving encryption area regarding a plaintext using the one-way increasing function where the increasing function parameter is applied, generate a second encryption area regarding the plain text using the secret key, and generate a ciphertext by concatenating the generated first encryption area and the generated second encryption area. |
